Hello,

I just changed all project references from referencing the installed dll's (Progress\Telerik UI for WPF R1 2023\Binaries\WPF45) to nuget version (e.g. Telerik.Windows.Controls.GridView.for.Wpf.Xaml). Unfortunately, this results in some controls not redering at all any more.

I see this especially at <telerik:Label>, <telerik:Button> and <telerik:GroupBox> (using xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation")

If I instead use the standard WPF <Label> in the exact same XAML file, the label gets rendered.

Is there anything special one has to apply/change/update if changing from the "installed" version of Telerik for WPF to the nuget based version?

Any help or idea much appreciated,

Sebastian

I have the following

For some reason the binding to MyCommand not triggering at all at my view model
Im using MvvmLight RelayCommand if it matters everywhere in my app

P.s 
I tried to change Button to RadButton and the result are the same

<UserControl>
   <Grid>
       <telerik:RadTabControl>
         <telerik:RadTabControl.AdditionalContent>
              <StackPanel Orientation="horizontal"
                                    DataContext="{Binding RelativeSource={RelativeSource FindAncestor, AnsectorType={x:Type UserControl}}, Path=DataContext}">
                      <Button Command="{Binding Path=MyCommand}">
                      </Button>
              </StackPanel>
        </telerik:RadTabControl.AdditionalContent>
       <telerik:RadTabControl.Items>
             <telerik:RadItem>
                  <!-- Here everything works just fine -->
              </telerik:RadItem>
       </telerik:RadTabControl.Items>
    </telerik:RadTabControl>
   </Grid>
</UserControl>

Hi Telerik,

Does Telerik support to export to .xlsb format
OR convert from .xlsx to .xlsb format?

Please let me know the solution for it.

Thanks and Regards,

Any idea for object reference not set to an instance of an object error?

Hi,

i try to save and load minimized ToolWindows. This works, but the original size gets lost.

Reproduce: Minimize ToolWindow, Save, Load, Restore -> wrong size

I atteched a simple sample where you can push the buttons from 1 to 4 to reproduce it. Pressing button 1 and 4 back and forth works as expected.
In the produced XML i see, that FloatingWidth and FloatingHeight is reset to some "strange" values (160 and 28) after minimize.
When i restore the Window after Load it gets a size of 1440x879

I also dont know how i can sneak in this process to "correct" the values or save some custom/attached ones ...

regards marco

What is the best way to reference telerik controls in a project?

I'm a new dev to my team, and I'm seeing telerik controls being referenced in Dependencies via Telerik.UI.for.Wpf.60.xaml in a folder that is under the users directory.

My problem relates to this being a dependency in a team members Windows Users folder (which I don't have) as well, after installing telerik controls myself and creating a new project from the telerik templates, I have a Telerik.UI.for.Wpf.70.xaml folder (not the 70 instead of 60).

First, what is the best way to reference telerik controls in a shared solution? And second, how do I get the code to compile and run?

Thank you any advice you can offer.

If I Set the ChartPanAndZoomBehavior to "Both", I can zoom a both within the same ratio or zoom one axis on its scrollbar.

How can I lock the two Axis to the same display ratio? (Same value/pixel ratio , I have the same unit meter on both axis)， and allow the user zoom only together with two axis, disable the func of zoom single axis. 

Hello,

we have old code for generate label with barcode Code39

var barcodeBox = new RadBarcode39
{
 Text = "2015-19541",
 RenderChecksum = false,
 ShowChecksum = false,
 ShowText = false,
 Width = 192,
 HorizontalAlignment = HorizontalAlignment.Center,
 VerticalAlignment = VerticalAlignment.Stretch,
 Margin = new Thickness(5, 0, 5, 0),
}; 

and have result https://ibb.co/3hgJHCw

after upgrade to new control with code

var barcodeBox = new RadBarcode
{
 Value = "2015-19541",
 Width = 192,
 HorizontalAlignment = HorizontalAlignment.Center,
 VerticalAlignment = VerticalAlignment.Stretch,
 Margin = new Thickness(5, 0, 5, 0),
 Symbology = new Code39()
 {
  AutoChecksum = false,
  ShowText = false,
  SizingMode = SizingMode.Stretch
 }
};

we have result https://ibb.co/k8hPdLp

Old barcode we can scan, but new barcode we cannot scan
