[Solved] ComboBox with internal TreeView...

[Kevin]

I've followed the example at: http://demos.telerik.com/aspnet-ajax/treeview/examples/functionality/treeviewcombobox/defaultcs.aspx

However, I need to be able to load the contents of the TreeView at runtime.  It's working fine if the treeview "exists" before the dropdown is activated, but because it's part of a template, the list is not "real" until runtime when the dropdown is used.

I've tried creating a different control and then swapping it in to no avail...

Any ideas?

Using the same demo I can get an instance of the TreeView by using the following ASPX and C# snippets:

ASPX:

<telerik:RadComboBox ID="DiscountComboBox" runat="server" ShowToggleImage="True"

ExpandAnimation-Type="None" CollapseAnimation-Type="None" Width="300px">

<ItemTemplate>

<div id="div1">

<telerik:RadTreeView runat="server" ID="DiscountTree">

</telerik:RadTreeView>

</div>

</ItemTemplate>

<Items>

<telerik:RadComboBoxItem Value="TreeView" />

</Items>

</telerik:RadComboBox>

C#:

RadTreeView discountTree = (RadTreeView)DiscountComboBox.FindItemByValue("TreeView").FindControl("DiscountTree");

As you see here I defined an ItemTemplate and then simply defined a singular item with a value so that I can find it using FindItemByVaue. This should be able to work whether or not you have actually used the ComboBox.

Excellent!  Thanks!
