title: How to set default value to asp textbox in radgrid while the texbox is data binded
body: <p>I have textbox code in .aspx file as below</p>
  
  <pre><code> &lt;telerik:GridTemplateColumn  UniqueName="Format" HeaderText="Format" DataField="SystemMessageTextId" HeaderStyle-Width="60"&gt;
                  &lt;ItemTemplate&gt;
                          &lt;asp:Label runat="server" ID="lblFormat" Text='&lt;%# Eval("Format") %&gt;'&gt;&lt;/asp:Label&gt;
                  &lt;/ItemTemplate&gt;
                  &lt;EditItemTemplate&gt;
                      &lt;asp:TextBox runat="server" ID="txtFormat" Text='&lt;%# Bind("Format") %&gt;' MaxLength="255"&gt;&lt;/asp:TextBox&gt;
                      &lt;span style="color: Red"&gt;*&amp;nbsp;
                          &lt;asp:RequiredFieldValidator ID="rfFormat" runat="server" ErrorMessage = "Please enter a valid Format value." ControlToValidate="txtFormat" Display="Dynamic"&gt;&lt;/asp:RequiredFieldValidator&gt;
                      &lt;/span&gt;
                  &lt;/EditItemTemplate&gt;
              &lt;/telerik:GridTemplateColumn&gt;
  </code></pre>
  
  <p>The .aspx.cs file looks like below</p>
  
  <pre><code> if ((e.Item is GridEditableItem) &amp;&amp; (e.Item.IsInEditMode))
  
   {
          GridEditableItem edititem = (GridEditableItem)e.Item;
         ((TextBox)(edititem["Format"].FindControl("txtFormat"))).Text = "pdf";
   }
  </code></pre>
  
  <p>I have this part in GridItemCreated function, but when I try it, the default value won't show. Can someone help me with this?
  Thanks</p>
