Combo box in a table column

I have dragged and dropped one of my view objects as a table on a JClient form. Is there a way I can show one of the columns as a combo box?

URGENT!!!!!!!! Using a topic title like "URGENT" followed by exclamations is one sure way to not get an answer from people on the forum.
This is urgent... Not for us it isn't. Implying that your question is any more important than any other question on the forum is another way to not get a response.
Anyway your question is like big run on sentence and I have no idea what you are asking or what your problem is or what your code looks like.
If you need further help then you need to create a [url http://homepage1.nifty.com/algafield/sscce.html]Short, Self Contained, Compilable and Executable, Example Program that demonstrates the incorrect behaviour, because I can't guess exactly what you are doing based on the information provided.
And don't forget to use the [url http://forum.java.sun.com/help.jspa?sec=formatting]Code Formatting Tags so the code retains its original formatting.

Linking combo boxes to a table

I have made a set of combo boxes that allow the user to input a home and away football team and their scores. I have also setup a table with 4 teams in it. How can i link the combo boxes so that EG:
If Arsenal 2 - 1 Chelsea is a result inputted how can i link it to a table so that Arsenal will go top with 3 points, 2 goal for, 1 against etc
Basically i need to update the table from the info supplied by the combo boxes???

we don't tolerate that attitude either....
besides I gave u guidelines, check the other thread, but u can be sure that nobody will help you if u keep this attitude...
READ the links I posted in that other thread, work on the issue then come back with questions and post your code so that we know how to help you based on your code..that's how it works here..

**urgent*** -two combo boxes -one database table - ***urgent**

1. i have one html page - in that two combo boxes are there
2. first one called--> Bank Name and second one called-->Main Branch
3. i have a database table like BANK_MASTER(MAIN_BRANCH,BANK_NAME)
i am giving here some data for the above table:
(sbi-kurnool, sbi),(sbi-cadapah,sbi),(sbi-chittor,sbi),(ab-rangareddy,ab),(ab-varangal,ab) ..like that every bank has its own main branch in different location.
MY PROBLEM:
In HTML page, in the first combo box ie., Bank Name will display all the bank name using the table BANK_MASTER ie.,sbi,ab,cb,sbh ...... (its ok - i too get )
main Problem: Whenever i select a particular bank name in the first combo box, the second combo box ie.,Main Branch has to display the main branches using the table Bank_Master depending on the Selected bank name from the Bank Name Combo box ( ie., if we select the sbi, it has to display all main branches of sbi's only, but not other bank's main branches)

I suppose that this can be done with StackPane but I need some other more universal way to do this because I want to expand the table size. I need to place there the combo box always in a fix position.

Hi. You can do it using an AnchorPane:
AnchorPane.setBottomAnchor(comboBox, 40.0);
AnchorPane.setLeftAnchor(comboBox, 12.0);
The complete example :

import javafx.scene.Node;
import javafx.scene.control.ComboBox;
import javafx.scene.control.TableColumn;
import javafx.scene.control.TableView;
import javafx.scene.control.TextArea;

Needs multi column dynamic combo box using C#

I need a dynamic Combo box to display multi columns on Drop Down Event
such as Stock Code, Make, Model,Sub Model, Measurement Type and so on for my C# Application with Columns Headers
Please Help Me
Thanks in Advance

You should create a class that represents your model and then you could use a CompositeCollection as the ItemsSource of the ComboBox.
Here is an example for you:
namespace WpfApplication59
public class YourModel
public string StockCode { get; set; }
public string Model { get; set; }
//+ the rest of your properties
MainWindow.xaml.cs:
public partial class MainWindow : Window
public MainWindow()
InitializeComponent();
List<YourModel> models = new List<YourModel>();
models.Add(new YourModel() { Model = "m1", StockCode ="c1"});
models.Add(new YourModel() { Model = "m2", StockCode = "c2" });
cb.ItemsSource = models;
MainWindow.xaml:
<ComboBox x:Name="cb" Grid.IsSharedSizeScope="True" ItemsSource="{DynamicResource items}"
xmlns:local="clr-namespace:WpfApplication59">
<ComboBox.Resources>
<CompositeCollection x:Key="items">
<ComboBoxItem IsEnabled="False">
<Grid TextElement.FontWeight="Bold">
<Grid.ColumnDefinitions>
<ColumnDefinition SharedSizeGroup="A"/>
<ColumnDefinition Width="5"/>
<ColumnDefinition SharedSizeGroup="B"/>
</Grid.ColumnDefinitions>
<Grid.Children>
<TextBlock Grid.Column="0" Text="Model"/>
<TextBlock Grid.Column="2" Text="Stock Code"/>
</Grid.Children>
</Grid>
</ComboBoxItem>
<Separator/>
<CollectionContainer Collection="{Binding Source={x:Reference cb}, Path=DataContext}"/>
</CompositeCollection>
<DataTemplate DataType="{x:Type local:YourModel}">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition SharedSizeGroup="A"/>
<ColumnDefinition Width="5"/>
<ColumnDefinition SharedSizeGroup="B"/>
</Grid.ColumnDefinitions>
<Grid.Children>
<TextBlock Grid.Column="0" Text="{Binding Model}"/>
<TextBlock Grid.Column="2" Text="{Binding StockCode}"/>
</Grid.Children>
</Grid>
</DataTemplate>
</ComboBox.Resources>
</ComboBox>
You could restyle the the templates (Grids) as per your requirements.

Trying to filter an entire database using a combo box or text box

Hi,
I am looking to create a combo box with rows vice columns, then I would like to create a macro or some for form of filter that gives me the option to search within each or all of the selections.
I have created a search function (using a textbox and the button features) that allows me to search for anything in my database using applyfilter. The problem that I ran into with this was that when I hit the might work, but only the first line worked.
So I tried to use a combination box to create a filter of the fields that I want to view for the particular search I need, but I want to select row headers vice columns of information. For example if I have five fields of: Last Name, First Name, SSN, Document
number and Unique ID.
I want a combination box to show the following field header when I click the drop down option.
(Last Name
First Name
SSN
Documentation Number
Unique ID)
Then I would to apply a macro filter feature for files within theses individual fields. I am just getting started in VBA and using Macros, so any help would be awesome!!
If I am too far off target please direct me back, I tend to over think things.
Thanks in Advance

Dirk Goldgar, I tried to you use the suggested method you gave me. Part of the problem I was having was that I wanted to view the field list, which I now know is very possible thanks to you, but only wanted it to show as one single list of fields.
So took the information you gave me and went on to create a list box instead. I later found out why this was not working either.
In what way was it not working? You can do the same thing with a list box as I described for a combo box.
I have relationships of tables attached.
I don't understand what you mean by that last statement, or how it's relevant to the discussion. Do you mean you have multiple different tables that you might want to filter? So you would need to either (a) first need to select a table from a
list of tables in your database, and only then select a field in that table, or else (b) have a table listing all the data elements you might want to search, with the table and field name of each, and base a list box on that -- then the code to search would
know what table to select from, as well as what field to filter on.
So this info that you provided was very helpful. I will continue to go through the link you provided.
So I can quickly sum up what I need:
1. A dropdown box that allows me to search any Field List
2. A textbox that allows me to type in the searchable information for that particular field.
3. Or some way to build a filter function for the whole list, with a textbox to search the key words.
This is all still a bit unclear to me, because I don't know whether you want to search a particular table, or any of many possible tables in the database.

Editable Combo box in a JTable

Hi,
Is it possible to have an editable combo Box in a JTable with an item Listener attached to the combo Box?
Based on whatever value the user enters in that column that is rendered as a combo Box(editable) i should be able to do some validation. Is this possible?
Thanks in advance for your time and patience.

Problem in event handling of combo box in JTable cell

Load Combo Box from MS Access

Me and a co-worker are trying to learn the Designer for a proof of concept (yes, that means newbies). We are currently struggling with loading a dropdown combo box from a table in an MS Access database. We have the connection set up and the field assigned to the control. It populates with the first record from the table, but clicking on the dropdown button does nothing. Is it only populating with one record? Is there a property on the control that is not allowing the list to expand?
I saw another thread in this forum on this topic and the last entry in the thread included the phrase "I GAVE UP" - not very encouraging. This functionality is a must-have and seems pretty basic.
Any advice?

I have been trying this using a Data Drop-down List and I cannot get it work. I have a data connection set up and instead of selecting Table from the choice I used an SQL query to select only one column in the table. There are three lines in the script some of which are confusing to me.<br /><br />var sDataConnectionName = "DataConnection"; //I got this one. it was easy<br />var sColHiddenValue = "<value>";<br />var sColDisplayText = "<value>";<br /><br />The last two I'm really not sure what to put there. I tried putting the name of the table column in place of each of "<value>". but it doesn't work.<br /><br />What else do I need to do to get it to work?

Combine table 3 columns in a combo box?

I need a combo box to display "lastName, firstName - phone".
I have these 3 columns in my database. Can anyone provide a short
cfc to xml script I could use to create an arrayCollection to use
as a dataprovider for my combobox?
I'm thinking along the lines of a CFQUERY in a cfc, then
exporting the results to an xml structure and using the xml as an
array collection. I just don't know how to do the cfc -> xml.
Any alternative solutions are welcome also. thanks

Bleh, double posted this due to forum maintenance.

How to Bind a Combo Box so that it retrieves and display content corresponding to the Id in a link table and populates itself with the data in the main table?

I am developing a desktop application in Wpf using MVVM and Entity Frameworks. I have the following tables:
1. Party (PartyId, Name)
2. Case (CaseId, CaseNo)
3. Petitioner (CaseId, PartyId) ............. Link Table
I am completely new to .Net and to begin with I download Microsoft's sample application and
following the pattern I have been successful in creating several tabs. The problem started only when I wanted to implement many-to-many relationship. The sample application has not covered the scenario where there can be a any-to-many relationship. However
with the help of MSDN forum I came to know about a link table and managed to solve entity framework issues pertaining to many-to-many relationship. Here is the screenshot of my application to show you what I have achieved so far.
And now the problem I want the forum to address is how to bind a combo box so that it retrieves Party.Name for the corresponding PartyId in the Link Table and also I want to populate it with Party.Name so that
users can choose one from the dropdown list to add or edit the petitioner.

Hello Barry,
Thanks a lot for responding to my query. As I am completely new to .Net and following the pattern of Microsoft's Employee Tracker sample it seems difficult to clearly understand the concept and implement it in a scenario which is different than what is in
the sample available at the link you supplied.
To get the idea of the thing here is my code behind of a view vBoxPetitioner:
<UserControl x:Class="CCIS.View.Case.vBoxPetitioner"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

mc:Ignorable="d"
d:DesignWidth="300"
d:DesignHeight="200">
<UserControl.Resources>
<DataTemplate DataType="{x:Type vm:vmPetitioner}">
<v:vPetitioner Margin="0,2,0,0" />
</DataTemplate>
</UserControl.Resources>
<Grid>
<HeaderedContentControl>
<HeaderedContentControl.Header>
<StackPanel Orientation="Horizontal" HorizontalAlignment="Right">
<TextBlock Margin="2">

</TextBlock>
</StackPanel>
</HeaderedContentControl.Header>
<ListBox BorderThickness="0" SelectedItem="{Binding Path=CurrentPetitioner, Mode=TwoWay}" ItemsSource="{Binding Path=tblParties}" />
</HeaderedContentControl>
</Grid>
</UserControl>
This part is working fine as it loads another view that is vPetioner perfectly in the manner I want it to be.
Here is the code of vmPetitioner, a ViewModel:
Imports Microsoft.VisualBasic
Imports System.Collections.ObjectModel
Imports System
Imports CCIS.Model.Party
Namespace CCIS.ViewModel.Case
''' <summary>
''' ViewModel of an individual Email

''' <summary>

Private petitioner As tblParty
''' <summary>
''' Initializes a new instance of the EmailViewModel class.
''' </summary>
''' <param name="detail">The underlying Email this ViewModel is to be based on</param>
Public Sub New(ByVal detail As tblParty)
If detail Is Nothing Then
Throw New ArgumentNullException("detail")
End If
Me.petitioner = detail
End Sub
''' <summary>
''' Gets the underlying Email this ViewModel is based on
''' </summary>
Public Overrides ReadOnly Property Model() As tblParty
Get
Return Me.petitioner
End Get
End Property
''' <summary>

Public Property fldPartyId() As String
Get
Return Me.petitioner.fldPartyId
End Get
Set(ByVal value As String)
Me.petitioner.fldPartyId = value
Me.OnPropertyChanged("fldPartyId")
End Set
End Property
End Class
End Namespace
And below is the ViewMode vmParty which vmPetitioner Inherits:
Imports Microsoft.VisualBasic
Imports System
Imports System.Collections.Generic
Imports CCIS.Model.Case
Imports CCIS.Model.Party
Imports CCIS.ViewModel.Helpers
Namespace CCIS.ViewModel.Case

Public Property fldName() As String
Get
Return Me.Model.fldName
End Get
Set(ByVal value As String)
Me.Model.fldName = value
Me.OnPropertyChanged("fldName")
End Set
End Property
''' <summary>
''' Constructs a view model to represent the supplied ContactDetail
''' </summary>
''' <param name="detail">The detail to build a ViewModel for</param>
''' <returns>The constructed ViewModel, null if one can't be built</returns>
Public Shared Function BuildViewModel(ByVal detail As tblParty) As vmParty
If detail Is Nothing Then
Throw New ArgumentNullException("detail")
End If
Dim e As tblParty = TryCast(detail, tblParty)
If e IsNot Nothing Then
Return New vmPetitioner(e)
End If
Return Nothing
End Function
End Class
End Namespace
And final the code behind of the view vPetitioner:
<UserControl x:Class="CCIS.View.Case.vPetitioner"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:vm="clr-namespace:CCIS.ViewModel.Case"
mc:Ignorable="d"
Width="300">
<UserControl.Resources>
<ResourceDictionary Source=".\CompactFormStyles.xaml" />
</UserControl.Resources>
<Grid>
<Border Style="{StaticResource DetailBorder}">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<TextBlock Grid.Column="0" Text="Petitioner:" />
<ComboBox Grid.Column="1" Width="240" SelectedValuePath="." SelectedItem="{Binding Path=tblParty}" ItemsSource="{Binding Path=PetitionerLookup}" DisplayMemberPath="fldName" />
</Grid>
</Border>
</Grid>
</UserControl>
The problem, presumably, seems to be is that the binding path "PetitionerLookup" of the ItemSource of the Combo box in the view vPetitioner exists in a different ViewModel vmCase which serves as an ObservableCollection for MainViewModel. Therefore,
what I need to Know is how to route the binding path if it exists in a different ViewModel?
Sir, I look forward to your early reply bringing a workable solution to the problem I face.

Access 2010 - How to display data from a table into a text box upon combo box selection?

Hi
I have a a table with 5 columns: month, year, USD, SGD, BAHT.
I created a form with a combo box for selection of the month and year, and I would like to set adjacent text boxes to show USD, SGD, BAHT information. How can i go about doing that?
From the Q&A here, most of them uses the function similar to this "=[Combo0].[Column](1)" to show the data in the text box, but this would require the combo box to list a whole bunch of details if i were to add in more currency values to the
table. Is it possible to not show this information in the combo box, but still populate data in the textboxes base on a selection on only the "month" and "year" in the combo box.

Hi,
According to your description, my understanding is that you want to show only the month/year in the combo box, we can choose the date, and it will display the value of USD/SGD/BAHT based on the month/year.
If it is, I recommend you try the steps:
Create a form based on your data source table>Add the combo box>combo box wizard>Find a record on my form based on the value I selected my combo box>Add mouth and year to selected fields
http://office.microsoft.com/en-us/access-help/create-a-list-of-choices-by-using-a-list-box-or-combo-box-HA010113052.aspx
If I misunderstand something, please let me know. We may upload some screenshots or a sample through OneDrive.
