Dynamic text box in Edit form template

[Adonis]

 I am trying to add dynamic text boxes inside of a edit form popup from radgrid, in a manner where a user can hit "add new text box" button and another text box for data entry would appear. I Have found a sample of code that does this in VB I am looking for some guidance on how this can be accomplished in the edit form template

Hello Adonis,

You can achieve this by creating one TextBox in EditItemTemplate and initially set its visibility as 'False'. Then when clicking on the 'add new textbox' button set its visibility as 'true'.

ASPX:

<telerik:GridTemplateColumn>
   <EditItemTemplate>
     <asp:TextBox ID="TextBox1" runat="server" Visible="false"></asp:TextBox>
     <asp:Button ID="Button4" runat="server" Text="add new textbox" CommandName="AddTextBox" />
   </EditItemTemplate>
</telerik:GridTemplateColumn>

C#:

protected void RadGrid1_ItemCommand(object source, GridCommandEventArgs e)
   {
     if (e.CommandName == "AddTextBox")
       {
           Button button = (Button)e.CommandSource;
           GridEditFormItem editItem = (GridEditFormItem)button.NamingContainer;
           TextBox txt = (TextBox)editItem.FindControl("TextBox1");
           txt.Visible = true;
       }
   }

Thanks,
Princy.
