For some reason, when my radgrid is displayed with no data in it, the right-most columns (the number of columns varies) disappear from view.  I have the ClientSettings scrolling properites set (allowscroll="true", UseStaticHeaders="true", ScrollHeight="500px").  When I remove these settings, the described effect does not occur.  We do have a need to have the scrolling clientsettings enabled as we are showing a substantial amount of columns on the page.  Is this a known issue and is there a suggested fix to my problem?  Thanks.

Hello Joshua,

I do not observe such a behavior locally. Here is my test page. Which RadControls version are you using?

<%@ Page Language="C#" %>
<%@ Import Namespace="System.Data" %>
<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>
 
<script runat="server">
 
    protected void RadGrid_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
    {
        DataTable dt = new DataTable();
        DataRow dr;
        int colsNum = 24;
        int rowsNum = 0;
        string colName = "Column";
 
        for (int j = 1; j <= colsNum; j++)
        {
            dt.Columns.Add(String.Format("{0}{1}", colName, j));
        }
 
        for (int i = 1; i <= rowsNum; i++)
        {
            dr = dt.NewRow();
 
            for (int k = 1; k <= colsNum; k++)
            {
                dr[String.Format("{0}{1}", colName, k)] = String.Format("{0}{1} Row{2}", colName, k, i);
            }
            dt.Rows.Add(dr);
        }
 
        (sender as RadGrid).DataSource = dt;
    }
 
</script>

I was able to fix my issue by specifying a really large value, in pixels, for the MasterTableView.  For some reason, the width of the MasterTableView was getting lopped off the end of the grid when it wasn't being set.  I'm not sure why this would be occurring.  any ideas?

Probably you are using an older version of RadControls - I think I recall this issue existed in the past.
