Custom DropDownList

I am trying to have a DropDownList that allows a user to select an index (a row) not by the user just clicking on the row, but rather by the user doing a mouse-down on the row and then dragging the row a little to the right and doing a mouse-up. The purpose of this can be thought of as a safety feature, so the row can only be selected if the user drags the row to the right and lets go rather than just clicking on the row.
In order to implement this, I decided to create a new class that extends DropDownList (in Spark). I am stuck because I am not sure exactly what to do next. I was thinking of overriding an inherited event. I've been looking through AS 3.0 reference for DropDownList (http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/spark/components/DropDo wnList.html)
and I find a bunch of inherited events, but none that seem to fire when a selection is made.
I am not sure of a way to implement this, so I am trying different things out to no avail.
If anyone can shed some light onto this with any suggestions on how to implement this sort of DropDownList I would really appreciate it.

Flex 4: Custom ScrollBar not working in Custom DropDownList

Hello,
I'm having an odd issue that I just cannot figure out. I have a custom DropDownList .as component (to pass color values) and a custom skin. In this skin I am using a custom Scroller (same AS file component with mxml skin). When I use this configuration, clicking on the scrollbar just closes the DropDown. If I remove the skin from my custom scrollbar it works, which leads me to believe it has something to do with the DropDown skin. Even if I revert my custom Scroller to the spark Scroller, it still doesn't work. I've narrowed it down to what seems like a problem with my DropDownList skin.
Not really sure what code to put here, but all I've been doing is right clicking my project and making new ActionScript components and MXML skins from the default skin. Here is my DropDownList skin, not sure if I should paste any other code? I have no idea what would be causing this, so I don't really know what code to place.
      [HostComponent("ccm.DropDown.DropDownList")]

Woops, the code didn't place correctly, here it is:

Relationship between a Spark DropDownList's dataProvider and selectedItem

I'm working on an existing project and have come across a somewhat complicated issue regarding a Spark DropDownList's (actually, a custom component inheriting from it) displayed item not changing when its dataProvider is updated.
Here's the code for the custom TitleWindow component containing the custom DropDownList:

I've omitted a little bit of code, so please ask if you need anything that I didn't include.
In regards to the RFDropDownList, originalValue is saved so that when a new selection is made, the new selection can be compared to the original value. Setting originalValue sets the RFDropDownList's selectedItem to originalValue.
When this window is first opened, a new instance of SiteEquipment is created. Unless the equipment is new, the SiteEquipment instance sets the SiteEquipmentType to whatever has already been saved, using this line:
eqType = SiteEquipmentType.selectFromObject(item.SITE_EQUIPMENT_TYPE);

            addToCache(this);
            updateFromResult(event.result.ROOT["DBO.SITE_EQUIPMENT_TYPE"]);
            dispatchEvent(new SiteEquipmentTypeEvent(SiteEquipmentTypeEvent.SITE_EQUIPMENT_TYPE_CREATE, this));
          else
            updateFromResult(event.result.ROOT["DBO.SITE_EQUIPMENT_TYPE"]);
            dispatchEvent(new SiteEquipmentTypeEvent(SiteEquipmentTypeEvent.SITE_EQUIPMENT_TYPE_EDIT, this));
            SiteEquipmentType.dispatchEvent(new SiteEquipmentTypeEvent(SiteEquipmentTypeEvent.SITE_EQUIPMENT_TYPE_EDIT, this));
        catch(ex:Error)
          Alert.show(ex.message, "Error");
          updateStatus = UpdateStatus.ERROR;
So the "_all" ArrayCollection serves as a cache of all of the different site equipment types. When the edit window is first opened and a new instance of SiteEquipment is created, the SiteEquipmentType of the current SiteEquipment is added to _all and becomes the only SiteEquipmentType within _all.
At this point, the DropDownList has the correct item selected. The problem occurs when the result comes in from getting all of the SiteEquipmentTypes. The contents of _all are flushed, and each SiteEquipmentType is added in. Once this happens, the DropDownList will have nothing for selectedItem.
I know this is quite complex, but any help would be greatly appreciated.

Ok, I have this figured out now. First, though, I'll point out that this worked fine when using MX components and the Halo theme; the problem only appeared after switching over to Spark components and the Spark theme. Anyway, since this class functions as a singleton (as best I understand them), I added a boolean variable to the SiteEquipmentType class representing whether or not the results from the HTTPService call had come back and been inserted into _all. So in the TitleWindow's init method, I only populated the DropDownList's originalValue (which in turn sets the selectedItem) if that variable is true. The first time an instance of the TitleWindow component is opened, though, this variable will initially be false. So back in the SiteEquipmentType class, I have it dispatch an event right after setting the variable to true, and the TitleWindow componet will add a listener for this event if the variable is originally false. If anyone needs further explanation, please ask.

How to make requestedRowCount work?

I am using this and it's not doing what I want.
<s:DropDownList id="ddlData" dataProvider="{parentApplication.acData}" labelField="name" prompt="Select" selectedIndex="-1" width="150">
<s:layout>
<s:VerticalLayout gap="0" horizontalAlign="contentJustify" requestedRowCount="11"/>
</s:layout>
</s:DropDownList>
What am I doing wrong please?

Just to clarify for better help, you want 11 rows of data to be displayed when using the dropdown list?
From Flex Examples
There is a slight “gotcha” when trying to set the requestedRowCount property >=6 . The default Spark DropDownListSkin sets a max height for the dropdown to 134px — which is roughly a requestedRowCount of 6 (unless the drop down menu has a horizontal scroll bar in which case the bottom item renderer is somewhat obscured by the horizontal scroll bar).
If you want to set the requested row count to higher than 5-6, you need to either create a custom DropDownList skin and remove the specified maxHeight (line 114 — as of 4.0.0.13895) or you can programmatically set the default DropDownListSkin drop down rowHeight property to NaN (Not a Number). For more information seehttp://bugs.adobe.com/jira/browse/SDK-25364.
This bug report shows a perfect example of this:

DropDownList as a custom renderer

Any idea how to create a custom renderer based on DropDownList for dataGrid?
Thanks

I'm sorry but that went a little over my head, could you point me in the direction of an example, alternativly I have extracted the following example from my application showing what I have so far. If I skin my ItemRenderer for the DropDownList, I'm worried it will upset the ItemRenderer for each of the items in the list!

How do I get a web part to display items from a dropdownlist?

I have a DropDownList that am filling with items from a list. The part of my code that am using to read the list and populating the drop down works just fine. I am now trying to figure out how to display the contents of the drop down on a web part. I know
it sounds like a straight forward and easy thing to figure out, but I have blanked out. Does anyone have a snippet I can take a look at? This is how I am currently reading from a list to create the drop down...
protected override void CreateChildControls()
string title = string.Empty;
EditorChoices = new DropDownList();
string siteUrl = "mySite";
using (SPSite site = new SPSite(siteUrl))
SPWeb web = site.RootWeb;
SPList list = web.Lists["testList"];
SPQuery testQuery = new SPQuery();
testQuery.Query = "<Query><Where><Geq><FieldRef Name='Title'/>" +
"<Value Type='Number'>10</Value></Geq></Where></Query>";
foreach (SPListItem item in list.GetItems(testQuery))
title = Convert.ToString(item["Title"]);
EditorChoices.Items.Add(title);
Controls.Add(EditorChoices);
base.CreateChildControls();
ChildControlsCreated = true;
I basically want to display the items returned from the query, which are now in the dropdownlist, to be displayed on my custom webpart. I really appreciate the help.
Thanks
UPDATE: My dropdownlist is a web part property. So when editing the web part, the drop down control appears in the web part property. Now that part is working just fine. The part am having an issue with is, the second part of my requirement is that I want
to display that same information within the drop down on the web part. Not as another drop down, but just to display them as a vertical text list on the web part.

Hello,
>I want to be able to display all the entteries in the dropdown,
Could you please provide more information? as per your description fisrt part is done, which was filling data in dropdown list. So what is next?
If you want to get selected value from dropdown or filter value then you may try this link:

Problem in using custom java beans

Hi,
We are using oracle JDeveloper 3.2.2 version for developing our Graphical User interface which
involves Applets and custom beans.
We faced the following problems when we tried to add the custom beans to JApplet.
Problem 1. When I drag and drop the custom beans to JApplet, the gif image used by the bean is
not displayed even when the gif image has been added in the archive file representing
JavaBean
Problem 2. When I modify the source code generated by Jdeveloper and come back to the design tab,
the custom beans looses its look and feel and gets the look and feel of the standard
bean from which it has been extended.
     For instance, I have a dropdownlist which has been extended from JCombobox.
     I drag and drop to the JApplet. The look and feel of the dropdownlist is
maintained.
Now I modify the source code for the dropdownlist in order to add items to it.
     After doing so, I come back to the design tab where i can see my dropdownlist
appears with the look and feel of JCombobox.

HI,
IF YOU create custom object the profile should be the same as standard.Also see whether the authorization object is added to the data target or not.
Hope this helps
Assign points if useful

Using itemCreationPolicy with a custom component

I'm working on a project where the users need to be able to have a 'filtered' view of one of the edit dialogs. I'm using view states to control which of the input fields show up for each view. The 'save' logic is the same for both states, so I still need to be able to pull data for the inputs even if they are not currently displayed. I tried setting itemCreationPolicy to immediate with no success. Some of the inputs were getting created but the initial values were not being set. The issue seems to be that the input component (an extended version of DropDownList) defers setting the selected value until the commitProperties() method. Since the inpit isn't actually being shown, the commitProperties() method is never getting called and the value is never being set.
Can anyone suggest a workaround for this issue? The only thing I can think of would be to use includeInLayout and visible to show/hide the inputs, but that is going to get really messy since I would have to apply it to every input and the FormItem components that enclose them.

Jasmin,
Is your class included in the custom component?
Yes, It is a annotated entity class,
When creating sessionFactory it is not loading the class.
i'm using flowing code block for creating sessionFactory,
factory =
new AnnotationConfiguration().addAnnotatedClass(dao.entity.UserEntity.
class).setProperty(
"hibernate.dialect",m_dialect ).setProperty(
"hibernate.connection.driver_class", m_driverClass).setProperty(
"hibernate.connection.url", m_connectionUrl ).setProperty(
"hibernate.connection.username",m_userName).setProperty(
"hibernate.connection.password", m_password).setProperty(
"hibernate.hbm2ddl.auto", m_hbmTodll ).setProperty(
"current_session_context_class",m_contextClass ).configure(resource).buildSessionFactory();
Is the jar referenced in the class patch section of the component.xml?
Yes , I have tried for this approch too , but class is entity class is not loaded.

Issue in rendering CustomToolpart to select data source for custom webpart..

I have a custom webpart in which i have added a tool part.This toolpart should allow me to select any list in the sitecollection which would be displayed on the webpage on doing apply in the webpart properties.The dropdown list with all lists is coming fine.The
grid is diplaying as well.But in the toolpart,not in the webpart. I cant seem to segregate the two.There is also a textbox in the toolpart in which the entered text comes in the webpart.But the same approach is failing for the gridview.Please suggest
what to do.
Also,i am failing at making a separate category for the toolpart by specifying [category("List settings")]..Any suggestion as to what i'm doing wrong in that are welcome too.

Hi,
According to your post, my understanding is that you have an issue about the custom web part.
Per my knowledge, we should customize the EditorPart instead of the
ToolPart to bind the lists to the dropdown list.
There is a good article about customizing web part, you can refer to it.
http://www.concurrency.com/blog/create-a-custom-web-part-for-sharepoint-2010/

Display a message when an item is selected from a dropdownlist

Hi,
I need to display a message(kind of alert message) when certain items are selected from the dropdownlist.
Let me know what is a good way to do this in web elements?
Thanks

hello,
unfortunately there is no validation / alerting for select menus in webelements.
however...if you're feeling ambitious and or this is a definite requirement for your project...custom functions are open source so you could write an on change javascript function within the WESelect custom function that will find the new value and compare it against your certain items array of values.
out of curiosity, what is your project's particular need to have an alert for a select menu based on what the end user selects? if this comes up more often or there's a good use case perhaps this could be built into a future version.

Problem with this version of DropDownLists, there is no removeItem function

Dear All,
I have a problem with this new version of the DropDownLists, in previous versions you had the removeItem function and others, but now you just have clearItems and addItem.
I have a list of elements in which a customer will be able to link and delete any element that he wants, I had selected a DropDownList to do that but considering that the removeItem function is not present I dont know how to do that...
Does anybody know how to delete a element in a dropdownlist?
If not, the solution will be to get all the elements in an array and reload the list but without the element "deleted" . Does anybody knows how to get all the elements of a DropDownList?
Thanks
Ruben.

If you have a drop-down list named myDropDownList,with SOMExpression
Form.page1.myDropDownList then you can remove the
element at position
i using the following code:
var myItems = xfa.form.resolveNode("Form.page1.myDropDownList.#items");
myItems.nodes.remove(myItems.nodes.item(i));
Good luck.

emptitle ---> TextBox1 Button1--> Text property : Search
empname---> TextBox2
empdepartment--> DropDownList1
For this, i wrote the code as follows:
protected void Button1_Click(object sender, EventArgs e)
using (SPSite mysite = new SPSite(SPContext.Current.Site.Url))
using (SPWeb myweb = mysite.OpenWeb())
SPList mylist = myweb.Lists["employeedetails"];
SPQuery query = new SPQuery();
query.Query = "<Where><Eq><FieldRef Name='Title'/><Value Type='Text'>" + TextBox1.Text.ToString() + "</Value></Eq></Where>";
SPListItemCollection myitems = mylist.GetItems(query);
if (myitems.Count > 0)
foreach (SPListItem item in myitems)
string a1 = Convert.ToString(item["empname"]);
string a2 = Convert.ToString(item["empdepartment"]);
TextBox2.Text = a1; // displaying properly
//DropDownList3.SelectedIndex = 1;
It is showing the list item in textbox according to the item entered in the textbox1... But I am stuck to show in the dropdown list.
Suppose, if i enter X in textbox and click on search, then dropdownlist need to show D1,
for Y --> D2 and for Z-> D3... like that.
What code do i need to write in the button_click to show this...
Please don't give any links...i just want code in continuation to my code.

Hi,
Since you have got the data you want with the help of SharePoint Object Model, then you can focus on how to populate values and set an option selected in the Drop Down List.
With the retrieved data, you can populate them into the Drop Down List firstly, then set a specific option selected.
Here is a link will show how to populate DropDownList control:

Another link about select an item in DropDownList:
