Hi,

My UI for WPF (2018 R1) used to work very well, but some days ago the design-time components stopped working. All the Rad controls lost their styles in the designer; however in run time they work just fine.

When Visual Studio (2017, v15.8.4) launches, it shows the following messages in the General output channel:

I tried every method I can find on the web with a related topic, including but not limited to deleting obj and bin folders, cleaning and rebuilding, reinstalling Telerik UI for WPF and Visual Studio etc. etc..

I tracked these exceptions down with Fusion Log Viewer, and it seems they are trying to load assemblies named Telerik.Windows.Data and Telerik.Windows.Core.Design, which unfortunately are not found by Visual Studio (however they do exist in the installation and the lib folder under my solution).

I tried to copy all the telerik.*.dll files to C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\common7\ide\ in order to let Visual Studio to find them, this successfully eliminated the error messages in the General output channel, however all the Rad controls now become invisible in the designer.

I think this issue started when I changed all the projects in my solution to target x64 CPU instead of Any CPU, but I'm not sure because the problem still exists when I switch them back to Any CPU.

Hi i'm using RadSpreadSheet inside a ControlTemplate and binding the control with Workbook property.

But it's not getting affected, whenever my binding is changed it does not get refreshed inside the control and the UI is not rendered.

And if i manually change the binding property at run time in xaml, then the control gets the binded and renders the data it on UI.

I have attached the code of the control in which i'm using the RadSpreadSheet.

Hi,

I would like to create and use a converter to change the background of a single selected button among the three buttons available. I don't want to handle a click event of the buttons and handle it from code behind and so tried different ways to create the converters, however it didn't work. Below I am providing a sample of my scenario. Any help would be greatly appreciated. Thank you.
 

<StackPanel Grid.Row="0" HorizontalAlignment="Center" x:Name="FirstRowControl" Orientation="Horizontal" Margin="232,0,233,0">
<telerik:RadButton Name="btn1" FontWeight="SemiBold" Margin="5" Content="Button 1" HorizontalAlignment="Left" VerticalAlignment="Top" Width="120" Height="25" BorderBrush="Black" Command="{Binding UpdateTabCommand}" >
<telerik:RadButton.CommandParameter>
<models:Tabs>Button1</models:Tabs>
</telerik:RadButton.CommandParameter>
</telerik:RadButton>
<telerik:RadButton Name="btn2" FontWeight="SemiBold" Margin="5" Content="Button 2" HorizontalAlignment="Left" VerticalAlignment="Top" Width="100" Height="25" BorderBrush="Black" Command="{Binding UpdateTabCommand}" >
<telerik:RadButton.CommandParameter>
<models:Tabs>Button2</models:Tabs>
</telerik:RadButton.CommandParameter>
</telerik:RadButton>

<telerik:RadButton Name="btn3" FontWeight="SemiBold" Margin="5" Content="Button 3" HorizontalAlignment="Left" VerticalAlignment="Top" Width="180" Height="25" BorderBrush="Black" Command="{Binding UpdateTabCommand}" >
<telerik:RadButton.CommandParameter>
<models:Tabs>Button3</models:Tabs>
</telerik:RadButton.CommandParameter>
</telerik:RadButton>
</StackPanel>

Code in the VM:
 
public DelegateCommand<Tabs?> UpdateTabCommand
{ get; }

public Tabs SelectedTab
{
get { return base.GetProperty<PedpTabs>(defaultValueFactory: () => Tabs.Button1); }
set { base.SetProperty(value); }
}

public enum Tabs
{
Button1,
Button2,
Button3
}


public ClassVM()
{
UpdateTabCommand = new DelegateCommand<Tabs?>(OnChangeTabExecute);
}


private void OnChangeTabExecute(PedpTabs? selectedTab)
{
this.SelectedTab = selectedTab ?? Tabs.StateChanges;
}

protected override void OnPropertyChanged(string propertyName)
{
base.OnPropertyChanged(propertyName);

switch (propertyName)
{
case nameof(SelectedTab):
OnTabChanged();
break;
}
}

private void OnTabChanged()
{
switch (SelectedTab)
{
case Tabs.Button1:
    MessageList = Messages2080;
    break;

case Tabs.Button2:
MessageList = Messages2088;
break;
case Tabs.Button3:
MessageList = Messages2010;
break;
}
}

Hi, I have a hierarchy that looks something like this:

<RadLayoutControl>

  <LayoutGroup>

    <LayoutExpanderGroup>
      <SomeControl/>
    </LayoutExpanderGroup>

    <LayoutExpanderGroup>

      <RadGridView/>

    </LayoutExpanderGroup>

  </LayoutGroup>

</RadLayoutControl>

My RadGridView has many columns and rows and so causes the entire <RadLayoutControl> to scroll.  Is it possible to configure this view so that only the <LayoutExpanderGroup> that contains the <RadGridView> will scroll?

Any help would be appreciated.

Hi,

I'm using the CloudUpload in my application, and I was wondering if there was anyway to update the tooltip language resource of the RadCloudUploadListItem Close Button (I joined a screenshot of the tooltip I'm talking about). I wasn't able to find it in the xaml style template.

Could someone help me with this issue?

Thank you,
