SelectRow seems to not work

Hi,

I have a Grid, on which a user can change certain fields, like on a right click they can increase a counter on the row by one (just changes a field by + 1, nothing else). Now when the user does this, the RowHandle seems to increment by 1. So if I was on row 0, it then goes to the second row in the grid (i.e. row handle 1). I've tried to write code to prevent this, by doing the following:

//From the right click event we get the row
var menuInfo = grdView.GridMenu.MenuInfo as GridCellMenuInfo;
var listIndex = grdDetail.GetRowListIndex(menuInfo.Row.RowHandle.Value);

... all the changing of stuff happens...

grdView.SelectRow(grdDetail.GetRowHandleByListIndex(listIndex));

(also tried with grdView.BeginSelection(); and grdView.EndSelection(); around this line, no change.)

But having debugged the code, everything looks fine, the listIndex is correct, and the GetRowHandleByListIndex returns the correct RowHandle, just just the SelectRow that seems to not be working as it should.

Or am I missing something?

Thanks.

Hi Richard,

Thank you for the report.

I'm afraid I do not quite understand under which conditions the situation you described occurs and how to reproduce it. However, I think I've found the cause of the problem. In fact, the SelectRow method works in MultiSelect mode only (please look at the Multiple Row Selection help topic to learn more). If that is not the case, you should manipulate the GridView's focused row instead. Please modify the code as follows:

[C#]
grdView.FocusedRowHandle = grdDetail.GetRowHandleByListIndex(listIndex);

If my guess is valid, this should help you address the issue.

Thanks,
Vito
