I try to insert a new row in a grid and then set a cell automatically to edit mode. The row is inserted via databinding to a business object, and not directly to the grid. The row is highlighted but no cell is in edit mode. If I first click on the grid and then inserts a new row it works for every new row thereafter. It's look like I am missing something the mouseclick do. A row insert is done by adding a new business object, and I deal with the new row in InitializeRow like this:
{
e.Row.Activate();
grid.ActiveCell = aCell;
}
The PerformAction seems to have no effect. If I click the grid first, it works as expected.
Some suggestion?
Kind Regards

Here's what I use for doing what you ask:
private void csfGridIkkeBehandletNemd_InitializeRow(object sender, Infragistics.Win.UltraWinGrid.InitializeRowEventArgs e) { UltraGrid grid = (UltraGrid)sender; e.Row.Activate(); UltraGridCell aCell = e.Row.Cells["Tekst"]; grid.ActiveCell = aCell; grid.PerformAction(UltraGridAction.EnterEditMode, false, false); grid.ActiveCell.SelStart = 0; }
Thanks.
But it seems that PerfomAction have no effect. I get an error if i try to do SelStart after
grid.PerformAction(UltraGridAction.EnterEditMode)
Error: (selStart are not supported while the cell is not in edit mode)
hi maggreen,
I had the same problem like you today. My solution is: I put the code to add a new row into the grid into the Shown event of the form and then all is fine. Try this, perhaps it helps. As Mike said it seams to me like a timing issue.
So... you are saying that the cell is not entering edit mode, even if you do not set the SelStart?
As I said, this worked fine for me when I did it. Are you using the same event I did - the Enter event?
Hello Mike
I have now also tried the enter event with the same result. But I would prefer to have the code regarding row insert in the click event for the "Insert Button".
I tried with insert new row in the insert button click event, and moved the activation of cell and PerfomAction in the enter event.
Some observation:
1) Then enter event is not fired unless I do a grid.Focus() in the button click event.
2) If I have not mouse clicked the grid, and then clicked the insert button: The enter event is fired once for each button click event because of the grid.Focus()
3) If I first have mouse clicked on the grid, and then clicked the insert button: The Enter event is also fired when the PerfomAction(EnterEditMode) is called within the Enter event.
maggreen: did you find any solution for this? I am having the exact problem.
I am having the exact same problem. Can anyone help?
No matter what I do and where I do it, the first cell is active, but will not enter edit mode without a mouse click.
the row is active, teh cell is active, but Performaction(.....EnterEditMode) just doesn't make it go into edit mode! ARRRGGGH driving me nuts.
Sorry for digging out such an old post ... Google send me here after searching for a solution to this exact same problem I had at work. Took a while to explore everything and finally we found out the cause of the error : the cell activation mode was set as "NoEdit" in the initialization of the Form.
Columns("NewDelai").CellActivation = Activation.NoEdit
so whenever we try to force the edit mode on this cell programmatically, we ended up with the same error OP got. ugRapport.PerformAction(UltraGridAction.EnterEditMode) ugRapport.ActiveCell.SelStart = 0
Hope this can help others too !
By trial and error...I've fixed the problem -- or at least worked around it. This is a threading issue on the Ultragrid. If I call: grid.PerformAction(Infragistics.Win.UltraWinGrid.UltraGridAction.EnterEditMode) directly (on the first row, first cell) it just doesn't work. However, if I set up a delegate and invoke the delegate, it works fine:
Private Delegate Sub PerformAction()
Sub WinGridPerformAction() grid.PerformAction(Infragistics.Win.UltraWinGrid.UltraGridAction.EnterEditMode) End Sub
Sub InitGrid() grid.DataSource = myDataSource grid.Focus() grid.DisplayLayout.Rows(0).Cells(0).Activate() Me.BeginInvoke(New PerformAction(AddressOf WinGridPerformAction)) End Sub
