RadGrid horizontal scrolling with too many columns

[Oleksandr]

Hi,

On my page I have a RadGrid control and I am creating columns dynamically. Also I have a child grid which suppose to be displayed for some records when user hits expand column. Now the problem I am facing is that the horizontal scroll is not displayed when the ExpandCollapse column is visible and the grid is trying to fit all the columns within page width which causing headers and data to overlap. When I am hiding ExpandCollapse column on ColumnCreated event all alignments and horizontal scrolling works as expected.
Any help is appreciated.

I'm using a 2008.3.1314.35 version of Rad Controls

Thank you.

Hi Oleksandr,

When using RadGrid scrolling with static headers, the MasterTableView's TableLayout is "Auto", unless one or more columns have explicit width. In this case the TableLayout becomes "Fixed" and all columns with no explicit width squeeze to fit in the MasterTableView. In your case the column with explicit width is the hierarchy expand/collapse column.

You should either set explicit column widths or a pixel width to the MasterTableView. An alternative approach is to remove the expand column's width at runtime, but this will most probably make it wider than usual:

C#

protected void RadGrid1_ColumnCreated(object sender, GridColumnCreatedEventArgs e)
{
    if (e.Column is GridExpandColumn)
    {
        e.Column.HeaderStyle.Width = Unit.Empty;
    }
}
