.NET Forum / Windows Forms / WinForm Data Binding / August 2008DataGridView BindingList keep sorted
Hi, I have IList<> of my objects bind to the DataGridView through BindingList<>. I want to keep my List<> sorted according to my sort order (i.e programatically set) when the user change add or delete rows. So I catch some events form DGV and sort my list list. For adding or deleting rows it works fine. I have just a problem with event CellValueChanged. When I sort the list in this event, then I cannot set current cell to the moved position. I just find the right position, set the dgv.CurrentCell = dgv[col, row]. But the current row stays in the old position. Where's the problem? Should I observe another event? I have one more question, is there any "straight" way to accomplish my task? I have tried to implement SortableBindingList<> from MSDN examples, but it does not keep list sorted. It just sorts the list when the sorting is called programatically. Thanks Hmm, it is strange, but the following code solved my problem: protected override bool ProcessDialogKey(Keys keyData) { Keys keyCode = (keyData & Keys.KeyCode); if (keyCode == Keys.Enter || keyCode == Keys.Tab) { return this.ProcessRightKey(keyData); } return base.ProcessDialogKey(keyData); } protected override bool ProcessDataGridViewKey(KeyEventArgs e) { if (e.KeyCode == Keys.Enter || e.KeyCode == Keys.Tab) { return this.ProcessRightKey(e.KeyData); } return base.ProcessDataGridViewKey(e); } -- http://xmedeko.blogspot.com Ahh, it was this code plus setting CurrentCell in CellValueChanged event. So, just to set CurrentCell in CellValueChanged didn't work without the overriding ProcessDialogKey and ProcessDataGridViewKey. -- http://xmedeko.blogspot.com > Hmm, it is strange, but the following code solved my problem: > [quoted text clipped - 16 lines] > return base.ProcessDataGridViewKey(e); > } Yeah, the main tric is to change Tab to the Right Key, by ProcessRightKey(). -- http://xmedeko.blogspot.com > Ahh, it was this code plus setting CurrentCell in CellValueChanged > event.
