I have a grid with SAVE button. Then I have a dockmanager which has 2 tabgrouppanes. The first tabgrouppane has a content pane which has a title textbox and few other fields.
Binding for title seems to happen only when we TAB out of the text box. Hitting SAVE without leaving the textbox does not do the binding. How do I get the textbox to receive a "lost focus" when I click on the SAVE button. Attaching sample code.
Thanks.
<Grid> <Grid x:Name="Grid_MenuBar"> <Button x:Name="Save" Grid.Column="1" Grid.Row="0" Margin="5" </Grid>
<igDock:XamDockManager Grid.Row="1" HorizontalAlignment="Stretch" VerticalAlignment="Stretch"> <igDock:XamDockManager.Panes> <igDock:SplitPane igDock:XamDockManager.InitialLocation="DockedTop" SplitterOrientation="Horizontal"> <igDock:TabGroupPane> <igDock:ContentPane Header="Primary"> <Grid x:Name="Song"> <TextBlock x:Name="SongTitle_txt" Text="Title" Grid.Row="1" Grid.Column="2" Margin="0,0,5,0" /> <TextBox x:Name="SongTitle_box" BorderThickness="0.5,0.5,0.5,0.5" Grid.Row="1" Grid.Column="3" Text="{Binding Path=Title, Mode=TwoWay, RelativeSource={RelativeSource TemplatedParent}}"/> </igDock:ContentPane> </igDock:TabGroupPane> </igDock:SplitPane> </igDock:XamDockManager.Panes></Grid>
In WPF, LostFocus is not the act of losing keyboard focus but the act of losing logical focus. In the case of the XamDockManager, the ContentPane is a FocusScope and as such each pane has its own logically focused element. So you would need to change the FocusManager.FocusedElement of the ContentPane to another element within the pane. Note, this is the same type issue that you would have if you had a TextBox on the Window and clicked on a Save button within a Toolbar or a Save button within a Menu or XamRibbon as all of those are focus scopes so that interacting within focus within those elements does not interfere with or manipulate the item that is focused in the other area. Alternatively you could change the Binding such that the UpdateSourceTrigger is PropertyChanged so that the value in the underlying source is updated as you type.
Thanks. That worked.
For my Winforms control, resetting the FocusedElement of the container ContentPane doesn't work. Do you have another idea of how I could handle this issue?
I'm not sure what you mean. You originally asked about XamNumericEditor and EditModeEnding. It's a WPF control. I don't think the FocusedElement in WPF has any relation/affect on any HwndHosts that may happen to be within it.
As I said in my previous post, the main problem is fixed (the XamNumericEditor send a LostKeyboardFocus when I click in another focus scope).
The other issue I have is not related to a XamNumericEditor. It is related to a Winforms control (a UltraWinGrid) which is not a WPF component but which is hosted in a WPF control. For this specific component, I don't receive the CellChange event when I click outside of the Winforms control. I guess the issue is more related to Winforms integration in WPF and not only related to Infragistics components behavior, but if you have any advice...
I'm guessing that relates more to the Leave event of a WinForms control. I'm not sure how a WindowsFormsHost deals with when it triggers the Enter/Leave events. You may want to check the MS forums or perhaps review the WindowsFormsHost code in Reflector/ILSpy. From MS' documentation on WPF/WinForms integration it seems like they don't raise the Leave events in some scenarios.
Ok. Thank you for your help.
