Attached is my page and masterpage. I'm trying is a couple of places in the vb code to cycle through the items collection to see which items are selected - the only item I ever see selected is the one I selected on load. The selectedItems collection only shows the single item as well. This is after I run in debug mode, open the page, and make multiple selections on the webdropdown.

Hello,

I've tried to reproduce the issue but without success. 

Please see my code in  FormView1_Item_Updateing handler:

  protected void FormView1_ItemUpdating(object sender, FormViewUpdateEventArgs e)

    {

        WebDropDown wdd = (WebDropDown)FormView1.FindControl("WebDropDown1");

        List<DropDownItem> items = wdd.SelectedItems;

        foreach (DropDownItem item in wdd.Items)

        {

            if (item.Selected) {

                Debugger.Break();

            }

        }

    }

Here I am able to get the selected Items.

In your code in the same Event you do only this:

 Dim ThisWebDropDown As WebDropDown = CType(Me.FormView1.FindControl("WebDropDown1"), WebDropDown)

but not actually access the Items of the control.

You try to reach the items of the control in FormView1_DataBound Event handler : as invoke this method  - Me.PopulateSystemTypes(); ,  So , since I'm not able to run your code I would suggest you to try get the selected Items in FormView1_ItemUpdating not in FormView1_DataBound. handler.

Let me know the result.

I thought I was done with this for the evening but I see one more thing. No events firing on the server for the webdropdown. I see this has been an issue for a bunch of people.

Looking at other threads, I've changed my declaration to..

                                <ig:WebDropDown ID="WebDropDown1" runat="server" DataSourceID="SqlDataSource_SystemTypes"
                                    TextField="Item_Text" ValueField="Item_Value"
                                    DropDownAnimationType="Linear" DropDownContainerHeight="0px" DropDownContainerMaxHeight="0px"
                                    DropDownContainerWidth="0px" EnableDropDownAsChild="True" EnableMultipleSelection="True"
                                    MultipleSelectionType="Checkbox" PageSize="0" Width="100%"
                                    StyleSetName="Default" StyleSetPath="~/ig_res"
                                    onselectionchanged="WebDropDown1_SelectionChanged">
                                    <DropDownItemBinding TextField="Item_Text" ValueField="Item_Value" />
                                    <AutoPostBackFlags ValueChanged="On" />
                                    <ClientEvents />
                                    <Button ImageUrl="~/ig_images/ig_cmboDownXP1.png" />
                                </ig:WebDropDown>
                                             

Changing selections does not cause a postback or fire the server side event. Also tried <AutoPostBackFlags SelectionChanged="On" /> instead - still no postback or event.

Hi,

You don't need Update or WARP panels for ajax functionality. The keyboard navigation issues are very strange. Also i am not sure why the server side events don't fire in your case. 

I will try looking at your sample. If i cannot reproduce your issues, we can go through it over WEbEx.

Thank you,

Well, I've had to refund my client's money for the Infragistics controls. I guess I own this.

I still have to make a multiselect listbox of some kind that actually works in order to keep them from cancelling my development contract which is now several weeks behind schedule - the last hurdle being this thing.

So far, it is obvious that the dropdownlist does NOT work in a formview.

I can at least get client side events to fire if it is not in a formview (taking code directly from the code samples page). Still seriously unreliable, but the events fire. Select 3 items, close the dropdown, *some* will show in the comma seperated in the closed dropdownlist control. Then unselect one - it still shows in the closed dropdownlist control. Some of the selected ones don't show in the dropdown.

Server events do NOT fire. Ever, from what I see.

I need help with this. Now.

Yes, I'm stressed.

I found it (at least partially).

It appears the server side events were not firing because my Webdropdowns had the same clientID in each of the formview templates (something I do all the time which normally works). Apparently with the webdropdown, events do not get bound correctly and they do not fire.

I gave the webdropdown a different clientID in each template, and suddenly my events fire and my selecteditems collection had the correct items on postback.

What a PITA, but now I have it mostly working.

Last question, How do I make the webdropdown NOT allow a user to change selections (ie read only). I've tried DisplayMode="ReadOnlyList" but the user can still check/uncheck selections.
