Determining if a grid row is visible

[Ken Law]

I''m trying to determine if a particular row in a virtual grid is visible or is scrolled out of view. I tried using GridControl.GetRowHidden(index) but this must be for some other purpose.
How can I check if a row is scrolled out of view using its index?

I''m using 3.2.1.0.

Thanks.

Hi Ken,

To determine the row visiblity in a grid , you need to use the ViewLayout.VisibleCellsRange collection. Here is a code snippet.

bool IsVisible = this.gridControl1.ViewLayout.VisibleCellsRange.IntersectsWith(GridRangeInfo.Row(2));
Console.WriteLine( Isvisible);

Let me know if this helps.

Heneef,

That worked perfectly - Thanks.

I have another question. By default the row header in my virtual grid is frozen (i.e. does not scroll). Is there an easy was to change this so the row header scrolls vertically like all the other cells?

Thanks,

Ken

Haneef,

Oops - I meant to ask how do you set the column header so it is not frozen and is allowed to scroll vertically along with the other cells in the grid.

Thanks,

Ken
