I currently have a form where an asp:TextBox is set as the OpenerElement of a RadWindow and it works fine.  However, I want to replace the TextBox with a RadTextBox and when I did that the RadWindow no longer opened and I don't know why.

Here's some sample code to illustrate this problem.

<form id="form1" runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server" />

<telerik:RadTextBox ID="radTextBox" Columns="30" ReadOnly="true" text="RadTextBox" runat="server" />
<asp:TextBox ID="aspTextBox" Columns="30" ReadOnly="true" text="AspTextBox" runat="server" />

<telerik:RadWindowManager ID="RadWindowManager1" runat="server">
<Windows>
<telerik:RadWindow ID="rwFindBranch" runat="server"
OpenerElementId="<%# radTextBox.ClientID %>"
NavigateUrl="http://www.telerik.com" />

<telerik:RadWindow ID="rwFindBranch2" runat="server"
OpenerElementId="<%# aspTextBox.ClientID %>"
NavigateUrl="http://www.google.com" />
</Windows>
</telerik:RadWindowManager>

</form>

Hi PJ Melies,

The reason for this behavior is that RadTextBox's ClientID is assigned to a hidden element. What you can do in such case is to set the property like this:

OpenerElementID='<%#radTextBox.ClientID + "_text" %>'


All the best,
