[Solved] Hide RadGrid Column using <% %>

[IT Support]

Hi,

I have the following code in the RadGrid of my UserControl:

<telerik:GridTemplateColumn UniqueName="MyColumnName" HeaderText="MyColumnName" Visible='<%# (Mode == SearchAndSelectMode.DataMode) ? true : false %>'>
    <ItemTemplate>
        <asp:ImageButton ID="MyButton" runat="server" ImageUrl="../App_Themes/eventIS/Grid/MyButton.gif" CommandName="DoSomething" />
    </ItemTemplate>
</telerik:GridTemplateColumn>

The "Mode" property is a public property of my UserControl, and I want to display this column depending on the value of that property. But when I run it, the following error appears:

Databinding expressions are only supported on objects that have a DataBinding event. Telerik.Web.UI.GridTemplateColumn does not have a DataBinding event.

I know it is also possible to hide the columns in code behind, but I want to do it in the ascx because then it is more clear what happens in my opinion. Is there any way to achieve what I want with the RadGrid?

Hello Raymond,

DataBinding expression can be used only with ASP.NET Controls and it is not possible to set the properties for RadGrid Columns using DataBinding Expressions. But probably you can try setting the visibility for the ImageButton using the same expression.
