Changing cell in TableNode not persisting

I am indexing into a cell table[1,0], so 2nd column first row. I set the .Text property.

When I step through the debugger I see that the value of Text has changed, but once finished I call diagramView.EndEdit(true); and then the text is empty for the cell.

Calling EndEdit() will raise the LeaveInplaceEdit and DestroyEditControl events. Perhaps you are setting the Text from a handler of these events?

Hi!

I want to use my own EditControl so I handle CreateEditControl event.

I have InplaceEditAcceptOnEnter = True & InplaceEditCancelOnEsc = True but I dont know why ESC & ENTER doesnt work for me. My EditControl is DevExpress.XtraEditors.TextEdit type. What do I need to set? Keypreview property?

So in this situation I handle txtTableCell_KeyPress event:

Code
Select All
Private Sub txtTableCell_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles txtTableCell.KeyPress
	  Select Case Asc(e.KeyChar)
		Case 27
		    'ESC
		    Me.fcDiagramView.EndEdit(False)
		Case 13
		    'ENTER
		    Me.fcDiagramView.EndEdit(True)
	  End Select
    End Sub


But calling Me.fcDiagramView.EndEdit(True) doesnt work for me. How I know in DestroyEditControl event or in LeaveInplaceEditMode event if changes was accepted? Do I need to transfer changes to e.Item manually? Or calling Me.fcDiagramView.EndEdit() is enough?

Thx for your answer.

Esc & Enter are handled automatically according to these properties only for the standard textbox. This is how DiagramView handles the TextBox.KeyPress event:

Code
Select All
private void OnInplaceTextBoxKeyPress(object o, KeyPressEventArgs args)
{
	if (inplaceAcceptOnEnter && args.KeyChar == (char)13)
	{
		EndEdit(true);
		args.Handled = true;
	}
	if (inplaceCancelOnEsc && args.KeyChar == (char)27)
	{
		EndEdit(false);
		args.Handled = true;
	}
}


The boolean argument of EndEdit s not passed to those events, and is used only with the standard textbox. You will have to assign it to some property of the custom edit control and check it when LeaveInplaceEditMode or DestroyEditControl is called.

I hope that helps,
Stoyan
