I have been struggling with this one far too long. It is very simple. A data bound grid bound to a data view containing 4 columns. The 4th column is a Boolean and is used to filter the dataview. If the 4th column is set to false the row should be removed from the grid. This is not happening. The user can set the value of the 4th column indirectly by clicking a button. I have tried two ways of setting the value of the 4th column. 1) Directly on the dataview. When I do this the grid will not remove the row until I click on a different row. _dvCompanies(_grdCompanyList.Binder.RowIndexToPosition(_grdCompanyList.CurrentCell.RowIndex))("Active") = False _grdCompanyList.Binder.EndEdit() _grdCompanyList.Refresh() 2) Through the binder. When I do this the grid will clear out the row, but not remove it. If I remove a second row the first remove is removed, but the second is blanked out. _grdCompanyList(_grdCompanyList.CurrentCell.RowIndex, _ _grdCompanyList.Binder.FieldToColIndex( _ _grdCompanyList.Binder.NameToField(“Active”))).CellValue = False If I sort the grid after any one of these two actions, the grid corrects itself. Please see full source below. Any help would be greatly appreciated.

Hi Per, Calling DataTable.AcceptChanges() fixes the issue. _dvCompanies[_grdCompanyList.Binder.RowIndexToPosition(_grdCompanyList.CurrentCell.RowIndex)]["Active"] = false; _grdCompanyList.Binder.EndEdit(); _dvCompanies.Table.AcceptChanges(); Best regards, Stanley

Hi Stanely, I can''t call AcceptChanges since it will reset the rowstate and I won''t be able to commit the changes later to the database. Do you have any other ideas? Thanks, Per >Hi Per, > >Calling DataTable.AcceptChanges() fixes the issue. > >_dvCompanies[_grdCompanyList.Binder.RowIndexToPosition(_grdCompanyList.CurrentCell.RowIndex)]["Active"] = false; >_grdCompanyList.Binder.EndEdit(); >_dvCompanies.Table.AcceptChanges(); > > >Best regards, >Stanley

Here is a little sample. http://www.syncfusion.com/Support/user/uploads/GDBG_Bool_7bfc3f2b.zip You can either check the checkbox to see the row removed (uses the grid.Binder.DirectCellSaveInfo setting.) Or, you can click the button and set the checkbox outside the grid on teh currentrow and see it removed.

Thanks Clay, that worked. >Here is a little sample. > >http://www.syncfusion.com/Support/user/uploads/GDBG_Bool_7bfc3f2b.zip > > >You can either check the checkbox to see the row removed (uses the grid.Binder.DirectCellSaveInfo setting.)
