I have developed a webpart in SharePoint Foundation 2010, and use RadGrid control in it. I have following codes:
Panel pnl = new Panel();
pnl.Width = System.Web.UI.WebControls.Unit.Percentage(100);
It runs well first. But after scrolling, UI RadGrid appears a vertical line and no border in header.
I have no set skin of RadGrid.
I have a attached screenshot.
Thanks in advance.
