Hello Kwang,

Try the following code.
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;
  DropDownList combo = (DropDownList)item["Gubun"].Controls[0];
  combo.DataSourceID = "SqlDataSource1";
}
}

Sorry But it's not my question point.

i want to get data  and bind dropdown list in server Page(aspx.cs , C#)

example :

protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)

{

   // if i get data to bind at here , how can i bind data .
     var q = from r in context.TableName
           select new {r.value , r.text};
 

if (e.Item is GridEditableItem && e.Item.IsInEditMode)

{

GridEditableItem item = (GridEditableItem)e.Item;

DropDownList combo = (DropDownList)item["Gubun"].Controls[0];

combo.DataSourceID = "SqlDataSource1";

}

}
