Telerik radgridview CellFormatting is not stable

Question

I have a radgridview with many columns (Horizontal Scroll Bar has been activated).
I have a CommandColumn in my grid & i want to format it like this :

private void rad_grd_Requests_CellFormatting(object sender, CellFormattingEventArgs e)
    {
        if (e.CellElement.ColumnInfo is GridViewCommandColumn)
        {
            RadButtonElement button = (RadButtonElement)e.CellElement.Children[0];
            if (e.CellElement.RowInfo.Cells["Admin_Action"].Value.ToString() == "Hold")
            {
                button.Text = "Done";
            }
            else
            {
                button.Text = "Done";
                button.Visibility = ElementVisibility.Hidden;
            }
        }
    }

When program starts every thing is ok.
But when i use horizontal scroll bar of grid some times all buttons in CommandColumn be invisible.(Multiple run of CellFormatting())
Why CellFormatting() is not stable & how can i fix this problem?

Here is the answer :

   RadButtonElement button = (RadButtonElement)e.CellElement.Children[0];
    if (e.CellElement.RowInfo.Cells["Admin_Action"].Value.ToString() == "Hold")
    {
        button.Text = "Done";
        button.Visibility = ElementVisibility.Visible;
    }
    else
    {
        button.Text = "Done";
        button.Visibility = ElementVisibility.Hidden;
    }

Add button.Visibility = ElementVisibility.Visible; to you codes.
