how to set value on checkbox colum in gridview

[Alessia]

Hello,

I have a gridview in which I inserted a GridTemplateColumn with a checkbox. The grid is loaded from your code and I can not set the checkbox value in the datatable.

Help
Best regards

Hello Alessia,

Give a try with the following code.

aspx:

<telerik:GridTemplateColumn>
     <EditItemTemplate>
          <asp:CheckBox ID="CheckBox1" Checked='<%# (DataBinder.Eval(Container.DataItem,"Attivo") is DBNull ?false:Eval("Attivo")) %>' runat="server" />
     </EditItemTemplate>
 </telerik:GridTemplateColumn>

and also refer the following forum which discussed the same scenario.
RadGrid Item Template Data Binding.

Thanks,
Shinu.
