Sort DataGrid with ComboBox

I have a DataGrid with several columns and I would like to be
able to sort it with a ComboBox. So if option a in the comboBox is
selected then column A in the DataGrid will be used to sort. I
option B is selected then a different column wil sort the DataGrid.
How would I go about this?
Thanks
Dave

Silverlight DataGrid with Combobox rendering problem

As you know that we have already implemented Silverlight application in our application, we need your help to resolve one issue that currently we are facing, actually this is a production bug. We are using Silverligh3 latest version. In our Silverlight
page we have one data grid and inside that we have one dropdown list as a column and others are textboxes. The dropdown lists are attached with the data context using two way binding. Now in order to simulate the issue, add multiple rows (using front-end ‘Add
Row’ custom button) on that data grid at runtime so that scrollbar is coming on the data grid, select data from combo boxes from first two rows, and after scrolling up and down for 2-3times causing combo boxes data disappeared from selected ones and it is
appearing on rows where no values are selected earlier. But if you reload the page then everything is coming as before. And we have checked that the data context object is purely ok and this is a layout refreshing problem only. I do not know whether this is
a bug of Silverlight or not, but as this is a production issue, I need your help urgently.

Thanks for your reply. I have simulated the problem in a test page which I have uploaded in this forum. As per your suggestion I have added the code but I doubt whether I have
done it properly. Please check the code as after incorporating the StackPanel also it behaves the same way. You will find the source code for Page1.xaml and the Page1.xaml.vb below in this page. Please review and let me know why virtualization is still active.

DataGrid with dynamic comboboxes

I need to design a dataGrid with comboboxes in one column. These comboboxes should all have different dataProviders based on a value from column 1. What would a general approach be?
Thanks

The renderer's data property is the data for the entire row so you can get the column1 data and assign the combobox's dataprovider accordingly.

Custom DataGrid problems with Comboboxes

I am using a custom datagrid with comboboxes and
colorpickers. I found this code on the web and adapted it to work
with my code. The only problem is that if you pull down a combobox
and then click somewhere outside without selecting anything, it
seems to erase the data in the dataprovider arraycollection and so
'value' in the set data method becomes null.

This is not a bug if I understand you properly. I believe most people would wish anything which is obtained via the tv to be backed up, which is why the content is transferred. If you want it to remain available on the tv you will need to sync it back to it.

FB4b1: Datagrid with data driven Combobox

Hi,
I would like to implement a datagrid with a datadriven combox in FB4b1.
The database should store "only" values, but should show a different labeltext in the grid.
When the users load this Grid the stores values should be uses to set the comboboxes.
That sounds easy but I haven't found a easy way to implement that!
1.) I need to overrite the "save column" function, so that the shown labeltext is not saved, but its db-values.
How can I do this?
2.) I need to build the combox in the datagrid, but there is nnothing like"combox.value="myValID" ( that would be all in vb.net)
Do I have to loop manually over the selectedIndex until I found my savedValue?
Like
http://www.boyzoid.com/blog/index.cfm/2006/11/22/Flex-Custom-Components-and-Custom-Methods
Is there an easier way to do this?
Thanks for any pointers!
Martin Zach

Each item in comobobox has a label and a data value associated with it.
The following should work if you were to access data of a selected combo box item, without looping through the items. If it is a string value then
mylabel.text = myCombo.selectedItem.data.toString() would show / store the associated data with the combobox item for the label text, you can replace mylabel with the datagrid's dataprovider for your requirements.
Hope this helps

Bind user generated info to DataGrid & edit with comboboxes

In my app, the user enters data which gets stored into a
class. I then wish to display this info in a DataGrid with three
columns corresponding to the data entered (2 strings and 1 number).
Is there an easy way to get this into the DataGrid by using binding
or do I have to do manual insertion of the data?
Also, I'd like to let the user edit the DataGrid. But I don't
want him to be able to just type whatever he wants, I'd rather give
him a pop-up or combobox with the relevant options.
Any suggestions about this approach?

When you say the data gets stored in a class, do you mean an
object? One way would be to store the data in a user data value
object and then bind the object parameters to your DataGrid. If
there are multiple users, you could put the object in an
ArrayCollection and bind that to your DataGrid.
You could then use an itemRenderer or itemEditor for each
column that would allow the user to update the values with
comboBoxes and the updates would be reflected in the stored object.

Combobox in Datagrid with different values

Hi All,
I have a datagrid. One of the columns in the datagrid is set
to display a combobox as the ItemRenderer. Now, the data for the
combobox is different for each row. How do I set up the data
provider for the combobox in such a scenario.
For example : I have a collection of Shirt objects.
public class Shirt {
public String id;
public String type;
public String[] color; //this is an array
This should be displayed in the datagrid, with the Color
column rendered as a combobox. The colors will be different for
each shirt.
Thanks
CS

Yes. Some more detail:
in the function,
override public function set data(value:Object): void {
the "value" parameter will contain a refernce to an entire
"Shirt" instance.
So you can assign the comboBox.dataProvider=value.color;
Now, It is more complicated than this, because you will want
the combobox to show the correct value for each row, right?
For this to happen, you will need a selectedColor property on
Shirt. When the user chooses a color, you will need to update this
property with the selection.
Next, your renderer must read the value of selectedColor and
set the comboBox.selectedIndex.
If selectedColor contains the *index* of the color then you
have it easy. If it contains the color name itself, then you will
have to for-loop over the color array until yom match the
selectedColor. then you will have the index and can set
selectedIndex.
ComboBox does not support setting the value directly. It is
pretty easy to extend combo to do this. There are several examples
out there. I posted a link to one on CFLEX.net

Martin Zach

Hi Martin,
Couple of questions
Are you using LCDS as your backend?
Are you using the Adobe data modeler and deploying your model on to your LCDS server?
If so, then you could try something called derived properties, which actually do not require a database column and you could compute its value based on the value of a existing column.
You can find more info about this on

Sorting Datagrid

argh, frustrating!
Is it really possible that I cant sort a datagrid with script
when user presses the button.
Lets say datagrid have three columns. Col 1, col 2 and col 3.
I have three buttons that lead user to the datagrid and each
of them should sort the datagrid by the column user clicked
(equivalent button)?

Just sort the underlying collection. Assuming your using an
arrayCollection
do the following:
userList.source.sortOn(["org","name"]);
This is a collection of user objects where I sort by org and
name.
Then either reset the grids dataprovider or send out a
Collection changed event:
var c:CollectionEvent = new
CollectionEvent(CollectionEvent.COLLECTION_CHANGE);
userList.dispatchEvent(c)

Need for a Datagrid with variableRowHeight="true" and custom Item Renderer to display exact rows

Hi again, developers:
I'm in a search of a datagrid with certain characteristics:
     - variableRowHeight = "true"
     - only one column
     - each row must have a custom item renderer with possibly different heights, and a fixed width
     - the datagrid must show always every item in the data provider with no vertical scroll bars, what means that the datagrid height must have always the exact height sum of all the item renderers it is displaying.
     - and no extra empty rows must appear in the last positions of the datagrid
The last two requirements are something difficult to achieve... for some reason, empty rows appear at the last positions of the datagrid. I post what i've managed to get:
<mx:Script>
     <![CDATA[
     private function resize():void
                if (dg.dataProvider)
                    var h:Number = dg.measureHeightOfItems( -1, dg.dataProvider.length);
                    dg.height = h;
     ]]>
</mx:Script>
<mx:DataGrid id="dg" width="530" horizontalCenter="0" verticalScrollPolicy="off"
        dataProvider="{dp}"
        wordWrap="true" variableRowHeight="true" showHeaders="false" dataChange="resize()" height="{dg.measureHeightOfItems(-1,dg.dataProvider.length)}" click="Alert.show(dg.rowCount.toString());">
        <mx:columns>
            <mx:DataGridColumn headerText="ID" width="50">
                <mx:itemRenderer>
                    <mx:Component>
                        <mx:TextArea height="{Math.random()*100}" wordWrap="true" backgroundColor="{Math.random() * 16777216}" paddingTop="0" paddingBottom="0"/>
                    </mx:Component>
                </mx:itemRenderer>
            </mx:DataGridColumn>
        </mx:columns>
    </mx:DataGrid>

Thanks Harui, but it doesn't help. If the border is set it will help, but the very big problem is the empty rows that appear at the end of the datagrid... I can't find a way of measuring correctly the height of the itemRenderers!
I'll update this thread if I manage to do it.

Strange Behaviour on DataGrid with ArrayCollection as DataProvider

I have a Datagrid with an ArrayCollection as DataProvider, the arrayCollection is partially generated by a remoteObject call, the dataprovider seems to works at least until I try to edit the field...
By the RemoteObject I only receive an ArrayCollection with the field `ip`, but the datagrid looks for the fields ip, check and save...
If I add/edit this new field it works, but only under particular condition
The DataGrid:
<s:DataGrid id="datagrid" left="10" right="10" top="136"
       dataProvider="{listaIPCheck}" bottom="10" requestedRowCount="4">
          <s:columns>
                <s:ArrayList>
                     <s:GridColumn dataField="ip" headerText="Asset"/>
                     <s:GridColumn dataField="check" headerText="Inventory"/>
                     <s:GridColumn dataField="save" headerText="Salvataggio"/>
                </s:ArrayList>
           </s:columns>
</s:DataGrid>
The Script:
   [Bindable]private var listaIPCheck:ArrayCollection;
    private function ro_resultHandler(event:Event=null):void
      listaIPCheck = new ArrayCollection();
      listaIPCheck = ro.getListUpdate.lastResult;
      heap = 0;
      // Read Below {POINT #1}
      init3();
    private function init3():void
     // Read Below {POINT #2}
     if (heap<listaIPCheck.length)
        // omitted the initialization of the process p
        p.addEventListener(NativeProcessExitEvent.EXIT, onExit);
        try{
          p.start(startupInfo);
        }catch(e:Error){}
    private function onExit(e:NativeProcessExitEvent):void {
        // Read below {POINT #3}
Here is my code, now as you can see there are 3 line where I wrote to read below...
Let's assume to put this simple `for` instead of the commented line (once at a time)
    for (var k:Number=0;k<listaIPCheck.length;k++)
      listaIPCheck.getItemAt(k).check = "checkVal";
      listaIPCheck.getItemAt(k).save = "saveVal";
This code always work in the 3 points, so at the end of the call the ArrayCollection is always filled with the new values, but the datagrid refresh the items only in POINT #1 and POINT #2
Why not in Point #3???

Thank you Amy, but adding the properties in the server side did not work...
The workflow of the program is that:
1) I get the ArrayCollection (listaIPCheck) contatining some information (function ro_resultHandler)
2) I start an external process and grab the output data (function init3)
3) read and use the data from the process (function onExit)
Now the problem I have is regarding the refresh of the datagrid, this datagrid has the ArrayCollection (listaIPCheck) as DataProvider.
So:
- If I put the for loop instead of the comments ( // Read Below {POINT #1} ) or
( // Read Below {POINT #2} ) it works, the ArrayCollection is updated and the datagrid is refreshed
- Whereas if I put the for loop instead of ( // Read Below {POINT #3} ) , it won't work.. or at least, the ArrayCollection is correctly updated, but the datagrid is not refreshed at all and I have to use .refresh()
