I should have given more information. I have a dropdown that is bound to a DataSet with AutoPostBack enabled as I want the selection to trigger the next code-behind step. This is how the application is currently deployed.

<

ig:WebDropDown ID="WebDropDownGroup" runat="server" Width="300px" AutoPostBack="True" onselectionchanged="WebDropDownGroup_SelectionChanged" DisplayMode="DropDownList"></ig:WebDropDown>

The user community is asking for list item filtering because the list is long and they do not want to scroll. I don't care if the filtering occurs client or server side. I was able to get client filtering working if I disabled AutoPostBack. I removed OnPreRender as it didn't seem to be needed. The problem is when I enable AutoPostBack I get a postback on each character I type to filter the dropdown.

<

ig:WebDropDown ID="WebDropDownGroup" runat="server" Width="300px" AutoPostBack="False" onselectionchanged="WebDropDownGroup_SelectionChanged" EnableAutoCompleteFirstMatch="False" EnableAutoFiltering="Client" EnableViewState="True"></ig:WebDropDown>

Is it possible to perform a postback on item selection but not when typing to filter in the dropdown list items?

In the referenced example, the _PreRender CS code does not compile because the .CurrentValue is set to four double-quotes. What is the proper value to assign?

ddServerFiltering.CurrentValue = """";

Additionally, my list is not filtering as I type and I'm not able to determine why. The datasource is set via CS code and I'm using 20111.2135

<ig:WebDropDown ID="WebDropDownGroup" runat="server" Width="300px" AutoPostBack="True" onselectionchanged="WebDropDownGroup_SelectionChanged" EnableAutoFiltering="Server" EnableAutoCompleteFirstMatch="False" OnPreRender="ddServerFiltering_PreRender"></ig:WebDropDown>
