colwidths and virtual grid

[Andy Ullman]

Hi,

I was wondering if it is possible to set the colwidths on a row by row basis in a virtual grid. The querycolwidth event seems to be called once for each col for the grid, not once for each col for each row. I''m trying to provide some grid within a grid functionality (like the gridgroupingcontrol) using a virtual grid.

Thanks

There is no way to very column widths row by row in a GridControl. A column width is a grid-wide property. But you can give the appearance of column widths varying row by row using covered ranges (for example, treating two side by side cells in a particular row as one cell). You can do this by explicitly adding the desired range to the grid.CoveredRanges collection, or you can use the event, QueryCoveredRanges to do it dynamically.

Does QueryCoveredCells get called for
every cell? If for example it is called
for cell 3,4 and in handling that event
you cover cells 3,4,3,5, will there be
another call to QCC for cell 3,5, or
does that get minimized out?

Hi Ralph,

Yes. The QueryCoveredRange event fires for every cell. When you specify the desired covered range using the QueryCoveredRange, the event minimizes for the desired covered range except the top-left cell range.
