i have a grid which is being filer by a xammulticolumn out side of the grid with the exact code off your sample site 'Programmatically Create a Filter' . The grid is grouped, when the filter is changed the group by numbers. if you scroll out of view and come back in the numbers will change. when you then clean the numbers will not go back. please proivde a fix asap

----THIS CELAR FUCNTION IS A HACK THAT I GOT FROM YOUR TEAM YEARS AGO CAUSE YOUR FILTERS DONT CLEAR PROPERLY----
public void ClearFilterCells(RowCollection rows) { if (rows != null) { if (rows.Count() > 0) { if (rows[0].RowType == Infragistics.Controls.Grids.RowType.DataRow) { foreach (Cell cell in ((RowsManager)rows[0].Manager).FilterRowTop.Cells) { (cell as FilterRowCell).FilterCellValue = null; }
foreach (Row dr in rows) { if (dr.HasChildren) { foreach (ChildBand childBand in dr.ChildBands) { childBand.RowFiltersCollection.Clear(); } ClearFilterCells(dr.ChildBands[0].Rows); } } } else { if (rows[0].GetType() == typeof(GroupByRow)) { foreach (GroupByRow gbr in rows) { gbr.RowFiltersCollection.Clear(); ClearFilterCells(gbr.Rows);
foreach (Cell cell in ((RowsManager)gbr.Rows[0].Manager).FilterRowTop.Cells) { (cell as FilterRowCell).FilterCellValue = null; } } } } }
Hello,
Thank you for your post.
Before I begin creating a sample project to test this, I would like to be sure I am under the correct impression for the issue you are describing. I am unsure what you mean by "The grid is grouped, when the filter is changed the group by numbers." I am under the impression that you are grouping the XamGrid and you are applying a filter to it. After applying the filter, the number representing the number of rows in each group-by section does not update until after you scroll the group by rows out of view and then back into view. Then, the numbers do not get refreshed when you clear the XamGrid filters either.
Am I under the correct impression here? If not, would it be possible for you to please provide some more detail on the issue you are seeing?

Just checking in, did you still require assistance on this matter?
