Hello Trunghieu,

You can access the control by using the FindControl method. Here is a sample code.

C#:

protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)
   {
       if (e.Item is GridDataItem)
       {
           GridDataItem item = (GridDataItem)e.Item;
           Image img = (Image)item.FindControl("okimg");//accessing the control
           Response.Write(img.ClientID);//accessing the properties
       }
   }

Also take a look at the help article.
Accessing Cells and Rows

Thanks,
Shinu.

Hello,

You are doing an incorrect cast. You should rather use:

RadGrid g = item.FindControl("RadGrid2") as RadGrid;
string gridId = g.ID; //for usage on the server-side
string clientId = g.ClientID; //for usage on the client-side
