how can i set the text property of the RadPanelItem using the inline c# code block? my code line is below. the variables are declared as global "protected string" in the c# code.

 

<telerik:RadPanelBar runat="server" ID="RadPanelBar1" Skin="Web20">
    <Items>
        <telerik:RadPanelItem Text="Quick Links" Expanded="true" PreventCollapse="true">
            <Items>
                <telerik:RadPanelItem Text="<%= textProperty %>" NavigateUrl="<%= urlProperty %>" />

Hi Syam,

You can use the DataBinder.Eval method to evaluate data from the container the expression is currently in.
Here is the API reference for this method: http://msdn.microsoft.com/en-us/library/4hx47hfe.aspx

Also, here is an alternative way of binding data, which by my opinion is the better (more clear for reading than the inline one):
<telerik:RadPanelBar ID="RadPanelBar1" runat="server" DataSourceID="SqlDataSource1" DataFieldID="id" DataFieldParentID="ParentId">
    <DataBindings>
        <telerik:RadPanelItemBinding Depth="0" TextField="Text" Expanded="true" />
        <telerik:RadPanelItemBinding FormatString="Level 1 > {0}" TextField="Text" Depth="1" />
        <telerik:RadPanelItemBinding FormatString=" Level 2 > {0}" TextField="Text"
            Depth="2" />
    </DataBindings>
</telerik:RadPanelBar>

For additional reference to dataBinding in RadPanelBar, here is a link to the "Overview" article in the DataBinding section of the help pages for this control: http://www.telerik.com/help/aspnet-ajax/panel_databindingoverview.html

Hope this is helpful for you!
