I've been using the "WPFDialogManagement" controls for popup message windows previously and they allow for command like this: 

dialogWait = dialogManager.CreateWaitDialog("We're good to go. This message will self destruct in 3 seconds...", DialogMode.Ok);
dialogWait.Show(() => Thread.Sleep(3000));

This pops up the message and then auto closes after 3 seconds if the "ok" button isn't pressed.

Is it possible to get a similar behavior with the RadWindow.Alert or by another means?

Thanks...

Hello,

I'm using the combobox in this example inside a grid as a celledittemplate:

http://www.telerik.com/community/forums/silverlight/combobox/multiselect-option-in-combo-box.aspx

I'm now stuck because I want to bind the comma separated values to the column dataitem, it is a string type.
I'm kind of new to wpf binding and I've tried a lot of things to get this done, but cannot achieve my goal.
please help.

Here's the column definition, Choices is the property I need to bind the results of the checked items.

Hi,

I would like to know if it's possible to have the same application button than the RibbonBar?

Thank's

We are using a RadBusyIndicator and everything is working fine, except the fact, that the BusyIndicator disables editing of enclosed controls in Design Mode.

Imagine there is a window with some buttons and textboxes and the BusyIndicator encloses these buttons and textboxes. During runtime enabling and disabling these controls via BusyIndicator works fine, but in VS2010 design mode you cannot e.g. shift the buttons around. Of course you can manually change the xaml code, but this is cumbersome.

Question: If I have integrated a BusyIndicator like this, how do I disable it during design time?

<telerik:RadBusyIndicator 
IsBusy="{Binding IsBusy, FallbackValue=False, TargetNullValue=False}" ...>
Some Buttons and TextBoxes
</telerik:RadBusyIndicator>


 

I have a RadGridView in a RadPane. The RadGridView has two fixed GroupDescriptors.

The pane is docked to the left by default and the first image shows the groupdescriptors working as intended. If I move the pane by dragging the header the groupdescriptors are instantly lost and I get the view in the 2nd attachment.

Is this normal behavior? If so is there a way to trap the event and stop this from taking place?

Thanks...

Hello,
I'm creating a new WPF application and would like to use implicit styles. The application currently uses the Windows8 theme.
I've added the references to the Telerik assemblies, including Telerik.Windows.Themes.Windows8.
In App.xaml, I have:

In Window1.xaml, I just have added a RadButton.
When I run the application, the button is displayed with the right theme, but the Visual Studio 2012 designer doesn't show the content of the button, as if the theme was not loaded.
How can I have the Visual Studio designer display the button correctly?

Hello, I have problem with radgridview.
Im using mvvm pattern. In viewmodel i implemented observablecollection which contain rows with data. : 
xaml:
        <telerik:RadGridView ItemsSource="{Binding MyCollection}"
                             x:Name="RadGridViewElement"
                             FilteringMode="Popup"/>

viewmodel:

 private ObservableCollection<myrow> myCollection = new ObservableCollection<myrow>();

        public kolekcja()
        {

            generatedata();
        }
        
        private void generatedata()
        {
           myrow row = new myrow();
            row.Imie = "aa";
            row.Nazwisko = "bb";
            myCollection.Add(row);
            myrow row1 = new wiersz();
            row1.Imie = "cc ";
            row1.Nazwisko = "dd";
            myCollection.Add(row1);
        }

        public ObservableCollection<wiersz> MyCollection
        {
            get { return myCollection; }
            set { myCollection = value; }
        }

Is there any option to return filtered  radgridview data rows  (update myCollection ? or save rows to other collection ?) I would like create graph with the filtered data . I looking for the easiest way to create column header filter from GUI (Just like [DisplayAttribute( AutoGenerateField = false )] ) 
any idea ?
kind regards

 

When I remove a node (using the DEL key) I want its connections to be removed too. As it is now, I get these orphaned connections when removing a node.

This is the scenario:
1) Node A is connected - through connection X - to node B.
2) B is selected. I press the DEL key. Both B and X are removed.
3) I press Ctrl+Z. Both the removal of B and X are undone.

This behavior is absolutely necessary for our product. How can I accomplish this?
