[Solved] RadComboBox ClearSelection

[Frank]

I know there are a number of threads with this issue, I just wanted to post my specific implementation and see if there is a solution to the corner I seem to be in.

Here is my combobox declaration:

<telerik:RadComboBox runat="server" ID="rcbAssetAssoc" ZIndex="100100" Enabled="false" AllowCustomText="false" MarkFirstMatch="true" Width="100%" Height="190px" EnableLoadOnDemand="true" HighlightTemplatedItems="true" OnItemDataBound="rcbAssetAssoc_ItemDataBound">
<HeaderTemplate>
<ul>
<li class="multiColBoxItem">Serial #</li>
<li class="multiColBoxItem">Asset #</li>
<li class="multiColBoxItem">Machine Name</li>
</ul>
</HeaderTemplate>
<ItemTemplate>
<ul>
<li class="multiColBoxItem"><%# Eval("SerialNumber") %></li>
<li class="multiColBoxItem"><%# Eval("AssetNumber") %></li>
<li class="multiColBoxItem"><%# Eval("MachineName") %></li>
</ul>
</ItemTemplate>
<FooterTemplate>
<asp:Panel runat="server" CssClass="multiColBoxFooter">
<asp:Label runat="server" ID="lblAssetAssocCount" SkinID="atBlueForm" />
</asp:Panel>
</FooterTemplate>
</telerik:RadComboBox>

I have read the solution to clear the selection as:

rcbAssetAssoc.Text = "";
rcbAssetAssoc.ClearSelection();

and that if the combobox is read-only the AllowCustomText="true" must be set to enable the clear to work.

However, if I set the AllowCustomText="true" that creates a bug in my code because I don't want the user typing in their own values.

Am I missing something?

At the end of the day I want a templated dropdown that forces the user to select one of the options with auto-complete style functionality AND have the box clear ready for the next selection.

Hello Brian,

 
One possible solution that worked properly at my side was adding a default item and using the ClearSelection after that as in the code below:

<DefaultItem Text="" Value="-1"/>
             <HeaderTemplate>

protected void RadButton1_Click(object sender, EventArgs e)
   {

       rcbAssetAssoc.ClearSelection();
   }

Hope this will be helpful.

Kind regards,
