Hello Nasri,

Try the following code snippet  to achieve your requirment.
C#:

protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)
    {
     if (e.Item is GridEditableItem && e.Item.IsInEditMode)//Check for Edit mode. Here its InPlace.
        {
            GridEditableItem editItem = (GridEditableItem)e.Item;
            RadComboBox combo = (RadComboBox)editItem["ColumnUniqueName"].Controls[0];
            combo.AllowCustomText = true;
        }
     }

Hello Nasri,

You can set the empty message by setting the EmptyMessage to the RadCombo.

C#:

if (e.Item is  GridEditableItem && e.Item.IsInEditMode)//Check for Edit mode. Here its InPlace.
        {
            GridEditableItem editItem = (GridEditableItem)e.Item;
            RadComboBox combo = (RadComboBox)editItem["ColumnUniqueName"].Controls[0];
            combo.AllowCustomText = true;
            combo.EmptyMessage = "SelectOne";
        }

Thanks,
Shinu.
