Hi,

Is there an easy way (= without having to use a complex ControlTemplate like in Kalin Milanovs answer (https://www.telerik.com/forums/how-to-change-the-selected-row-style)) to change the backgound color of the selected row ?

I've tried using a Trigger:

    <Style x:Key="DefaultTelerikGridViewRowStyle" TargetType="telerik:GridViewRow">
        <Setter Property="Height" Value="20"/>
        <Style.Triggers>
            <Trigger Property="IsSelected" Value="True">
                <Setter Property="Height" Value="24"/>
                <Setter Property="BorderBrush" Value="Green" />
                <Setter Property="BorderThickness" Value="3" />
                <Setter Property="FontWeight"  Value="Bold" />
                <Setter Property="FontSize" Value="14"/>
                <Setter Property="Background" Value="Red"/>
                <Setter Property="Foreground" Value="Green"/>
            </Trigger>
        </Style.Triggers>
    </Style>

This works fine for every property in the Trigger, except for the Background color.  How come ?

Kind Regards

Hi

I need to dynamically create and delete RadDateTimePicker object. However, I can not fully delete the RadDateTimePicker. This can cause a memory leak. Let me give the sample example to illustrate my problem.

for(int b=0;b<10000;b++){

  for(int a=0;a<100;a++){
    RadDateTimePicker radDateTimePicker = new RadDateTimePicker();
    radDateTimePicker.InputMode = InputMode.DatePicker;
    radDateTimePicker = null;
  }
  long memory = GC.GetTotalMemory(true);
  System.Diagnostics.Trace.WriteLine(xxx.ToString() + " - " + (memory / 1000).ToString() + "K");
}

I found that If I set the InputMode the memory will keep increasing (Memory leak).  Otherwise, the memory will not keep increasing. Could you please help to solve this problem. 

Thank you very much

Hello,

I am currently evaluating the Telerik WPF controls for use in our application. So far it's looking good but I have a question about how to build the project on a build server.

I understand that each developer needs their own licence, and each developer needs to install the controls on their development machine.

Currently I have installed the controls on my machine and my project references the .dlls from the Telerik install directory in Program Files. What do I need to do to build my project on our build server? Right now the build would fail because the build server does not contain the Telerik .dlls.

- Do I need to install the controls on the build server (rather than just copying the .dlls)?
- Do I need an additional licence for the build server?

Thanks,

Chris

WPF, Caliburn.micro, mvvm.

My ViewModel have a BindableCollection<String> that is loaded with from 1 to 1000 string values.

In my view, I have a listbox that is bound to the collection. The list box shows all the data, but in one colunm with a scroll bar.  What I want is the data in three columns and scroll bars if the data can't fit.

Can anyone point me in the right direction?

Hello!

I have a question about sorting string columns in the RadGridView component.

Lets say I have the following rows;

• V1
• V2
• W1
• W2 

When using the built-in sorting these are sorted as; V1, W1, V2, W2.

But here in Sweden the characters 'V' and 'W' are treated as separate characters.

So I would like these to be sorted as; V1, V2, W1, W2.

Is there some kind of setting I can use to resolve this or do I need to implement some kind of custom sorting?

Kind regards,

Fredrik

Hello,

I'm trying to use busy indicator. What I've done is declaring it as static field for in my App class. I can call and change it from wherever I want, the thing is, I do not know how to call it correctly. My intuition told me to do something like this:

And in new page constructor I'm calling App.BusyIndicator.IsBusy = false.

The problem is, that Indicator is awaiting Page to load and showing exaclty on the same time as page does. I want it to render and show before my page loads. Technicly and intuitively it should work as intended, but I guess there is some render-related issue here, so window doesn't want to show indicator before all stuff is rendered. The thing is, I want to keep indicator as simple as possible, without so much code and preferably without XAML styling and overriding anything. How can I do it in the way I want? Is it possible?

Thanks in advance

Hello,

I'm developing application with ADO DB, using telerik. Currently my problem is to reload data of RadGridView after I commit changes to DB from another window.

My app structure is Window (main window) with Pages inside. In some places I'm calling window.ShowDialog() (<- dialog window), and those windows contains some editable data, which I commit to db. And after I commit those data I want to refresh my page, inside my main window. However, pages aren't static, so I can't simply call any refresh of their containters from my dialog window. Is there any way to set something like listening to page, which is triggered after dialog window is closed? Or is there any other way to refresh data on window closing?

Hello,

I am trying to create a Diagram, using RadDiagram, and I want to apply some custom styles using StyleSelectors.

My main issue is that when I apply a ShapeStyle to a RadDiagram (even static) then the shapes disappear!The same happens with the connections.

Even the simplest examples from Customize the RadDiagramShape Style do not work! I use Telerik 2017.3.1018.45.NoXaml version and I have added the following dictionaries:

My MainWindow.Xaml
