Handling of Paste Command

[Uli]

Hi,

I implemented my own paste handling. Therefore I set the property RadGridView.ClipboardPasteMode to GridViewClipboardPasteMode.None. This worked perfectly for version Q3 2010. Now I update to Q2 2011. With this version my handlers of the command ApplicationCommands.Paste are not invoked any more. I noticed that now the method GridViewDataControl.PasteCanExecute contains the statemente: e.Handled = true. I think this does not make sense for GridViewClipboardPasteMode.None.

Is this a known issue? Will it be fixed? Is there a workaround?

Best regards

Uli

Hello Uli,

Sorry for the late reply.

The problem comes from the fact that RadGridView handles KeyDown event (ctrl + v) when any RadGridView command is performed and therefore Application.Paste command is not invoked. You can take a look this blog post for more information how to customize keyboard behavior.

Let me know if this doesn't help.

Hello Nedyalko,

the problem has nothing to do with key handling. There is the same behavior if I invoke the Application.Paste command via menu or toolbar. I am quite sure that the problem comes from the change in the implementation of the method GridViewDataControl.PasteCanExecute.

Hi Uli,

Could you please try your scenario with our latest internal build (2011.2.0808) and let me know how it works?

Hello Nedyalko,

it's the same behaviour with the 2011.2.0808 build.

Hi Uli,

I'm attaching a sample project which can give you an idea how to achieve the desired behavior with our latest internal build.
Let me know if there is something unclear.

All the best,

Hi Nedyalko,

I'm sorry, but the solution you demonstated in your sample is not acceptable for our application. We can't use a custom command but we have to use the predefined ApplicationCommands.Paste because this is supported by all standard controls. We just want that when RadGridView.ClipboardPasteMode is set to GridViewClipboardPasteMode.None that the GridView ignores this command. Just the way it has been implemented in release Q3 2010.

Best regards

Hi Uli,

Could you please send me a code snippet that demonstrates how you are using ApplicationCommands.Paste in your code?
Thank you in advance.

Hi Nedyalko,

in the menu of the main window I have a MenuItem bound to ApplicationCommands.Paste:

<MenuItem Header="Paste" Command="ApplicationCommands.Paste">

In the constructor of the UserControl that contains the RadGridView instance I set the ClipboardPasteMode property to GridViewClipboardPasteMode.None and add a binding to the Paste command.


<P>        public

MyListView()<BR>       

{<BR>           

InitializeComponent();</P>

<P>           

RadGridView1.ClipboardPasteMode =

GridViewClipboardPasteMode.None;<BR>           

CommandBindings.Add(new CommandBinding(ApplicationCommands.Paste, ExecutePaste,

CanExecutePaste));<BR>        }</P>

<P>        private void ExecutePaste(object

sender, ExecutedRoutedEventArgs e)<BR>       

{<BR>            // ...

my paste code<BR>        }<BR></P>

 

If the keyboard focus is within the RadGridView I expect that the handler ExecutePaste is called as it has been in release Q3 2010.

Best regards
Uli
