RadGrid grouping causing columns to be resized

[wonderbison]

Hi

I have a master/detail ASP.NET setup with a grid in the middle cell of the master/detail setup. Below is the setup of the grid. When I drag a column up to be grouped, the grid shrinks from a horizontal scrollable grid to one where all the columns are shrunk so that they fit without scrolling. Searched high and low for the necessary setting but to no avail.

Help appreciated

Hi Robin,

If you are using scrolling with static headers, the master table's layout is "auto" and there are no column widths specified, the columns will shrink to fill the minimum required space - this is expected.

In order to avoid this, please either set column widths, or set TableLayout="Fixed".

All the best,
