                                               <ItemTemplate>
                                                   <a class="FotoGrid" href="#" onclick="VerImagen($(this))">
                                                       <telerik:RadBinaryImage ID="RadBinaryImage2" runat="server" AlternateText='<%#Eval("Contenido", "Photo of {0}") %>'
                                                           AutoAdjustImageControlSize="false" DataValue='<%#Eval("Contenido") is DBNull ? null : Eval("Contenido")%>'
                                                           Height="80px" ToolTip='<%#Eval("Contenido", "Photo of {0}") %>' Width="80px" />
                                                   </a>
                                               </ItemTemplate>
                                               <EditItemTemplate>

Hi,

Try the following code to access the controls in edititemtemplate from client side.
C#:

protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)
{
 if (e.Item is GridEditableItem && e.Item.IsInEditMode)
 {
   GridEditableItem item = (GridEditableItem)e.Item;
   RadAsyncUpload upload = (RadAsyncUpload)item.FindControl("upload");
   RadGrid1.Controls.Add(new LiteralControl("<script type='text/javascript'>window['upload'] = '" + upload.ClientID + "';</script>"));
 }
}

JS:

function OnClientClick()
{
  var upload = $find(window['upload']);
}

Thanks,
Shinu.
