Frozen columns in a Popup Panel

[daxriders]

Hi,

I'm trying to display a Grid in a Popup Panel. The problem is when the popup is first diplayed the columns are not frozen. Only after I click on a column's header for sorting, will the "column freezing" work.
Any idea why is that so? Or how to fix this and make the "column freezing" work on display?

Thanx.

Dax

Hi Daxriders,

When you are using frozen columns with scrolling enabled and UseStaticHeaders is True, you should set fixed widths for your grid columns (through their HeaderStyle -> Width property) or TableLayout = Fixed for the MasterTableView. Note that the default table layout for the grid with scrolling enabled is auto and this may cause the unwanted effect when you enable the frozen columns functionality.

Additionally, please review the following article which elaborate on this subject:
