Thanks in advance

Hi,

One suggestion is that you can set ReadOnly property as true for the column that is not needed to show in insert mode and show the combobox using InsertItemTemplate.
aspx:

<telerik:GridTemplateColumn>
      <InsertItemTemplate>
          <telerik:RadComboBox ID="RadComboBox1" DataSourceID="SqlDataSource2" DataTextField="Id" DataValueField="Id" runat="server"></telerik:RadComboBox>
      </InsertItemTemplate>
</telerik:GridTemplateColumn>

Thanks,
Princy.

Ok, i dont think i understand what event im gonna set the property in. Does any event fire when i press Add new record button, where i can manipulate the form before its rendered?

Hi,

You can check for the event in ItemCommand event as shown below.
C#:

protected void RadGrid1_ItemCommand(object sender, Telerik.Web.UI.GridCommandEventArgs e)
{
 if (e.CommandName == RadGrid.InitInsertCommandName)
 {
 }
}

Thanks,

Ok, ive managed to accomplish to get a combobox to show and hide the textbox, but i want the combo box in the same place the textbox was, cant i just replace it insetead of adding a new control and hiding the old one?

Seems very complicated to do such a simple thing, cant i manipulate the collection of input controls somewhere directly?

Hi,

One suggestion is that you can set the Visibility of the controls in Edititemtemplate as shown below.
aspx:

<telerik:GridTemplateColumn>
     <EditItemTemplate>
     <asp:TextBox ID="TextBox1" runat="server" Visible='<%#(Container is GridEditFormInsertItem)? false : true %>'></asp:TextBox>
      <telerik:RadComboBox ID="RadComboBox1" DataSourceID="SqlDataSource2" DataTextField="EmployeeID" DataValueField="EmployeeID" runat="server" Visible='<%#(Container is GridEditFormInsertItem)? true : false %>' ></telerik:RadComboBox>
      </EditItemTemplate>
</telerik:GridTemplateColumn>

Thanks,
Princy.
