We are getting this error message on the latest mac os only (Ios 12) and only on Safari. 

TypeError: null is not an object(evaluating 'document.getElementById('ctl00_PageContent_QUES_TITLERequiredFieldValidator') ['controltovalidate']="ctl00_PageContent_QUES_TITLE"')

TypeError: null is not an object (evaluationg 'b._behaviors') Telerik.web.ui.webresource.axd:6:7292

TypeError: null is not an object (evaluationg 'a.control=this') Telerik.web.ui.webresource.axd:6:7420

This does not happen on a mac using chrome nor on any browser on windows or linix.

 

Any help would be appreciated.

Hi,

when can we expect support for 1.0.0-preview1?

Or do we have to wait until 1.0 stable is released?

Thanks
Martin

P.S. a general tag is missing, I used Gauge because that's what I want to use later on. but does not relate to my question.

If I comment out the columns section it loads. So how did you guys get to work? Dylan sent me a ChartViewTest project and I dropped this section in replacing the chart (that works) and it still threw and exception so I know it is not a requirements or configuration issue. What am I doing wrong. Running out of time on this eval.  Thanks. 

  xmlns:grid="using:Telerik.UI.Xaml.Controls.Grid" 

     <grid:RadDataGrid AutoGenerateColumns="False"
                                 SelectionMode="Single"
                                 SelectionUnit="Row"                                 
                                 >
                <grid:RadDataGrid.Columns>
                    <grid:DataGridTextColumn Header="Name"/>
                </grid:RadDataGrid.Columns>
            </grid:RadDataGrid>

I get this...

System.Runtime.InteropServices.COMException: Error HRESULT E_FAIL has been returned from a call to a COM component.
   at Microsoft.UI.Xaml.UIElement.Measure(Size availableSize)
   at Telerik.UI.Xaml.Controls.Grid.DataGridColumn.MeasureCellContainer(Double availableWidth, UIElement container)

   at Telerik.UI.Xaml.Controls.Grid.RadDataGrid.MeasureHeaderCell(GridHeaderCellModel cell)
   at Telerik.U

Hey guys. Took a clip from your WinUI demo. Attached as simple user control. Using this version of WinUI SDK (from project file) and I get this odd error. How did you guys get that to work? If you want I can create a complete project. Demo source would help. Thanks.

    <PackageReference Include="Microsoft.WindowsAppSDK" Version="1.0.0-experimental1" />
    <PackageReference Include="Microsoft.WindowsAppSDK.Foundation" Version="1.0.0-experimental1" />

When trying to debug my Application according to your manual (https://docs.telerik.com/devtools/winui/getting-started) this error appeared in my Debugging Session:

NameWertTyp
â–¶Exception{"Error HRESULT E_FAIL has been returned from a call to a COM component."}System.Exception {System.Runtime.InteropServices.COMException}

It happens when I'm trying to set the ItemsSource of my DataGrid.

I'm using the same declarations as described in your manuals example of using a DataGrid.

I've configured my environment according to the following specifications:

Visual Studio  16.11.1

Project Reunion 0.8.2

Telerik UI For Win UI 0.4.0 | I'm referring to the Win32-Assembly of Progress Control Panel

Are there any known issues with the current setup of 0.4.0 as described in this link (https://www.telerik.com/forums/is-winui-in-desktop-currently-supported)?

Hi,

My Setup:

Installed WinUI 3 Preview 4
Created a new project based on the "Blank App, Packaged (WinUI in Desktop)" template
Added a project reference to Telerik.WinUI.Controls.dll
Changed MainWindow.xaml to
<Window>...
     <Grid>
        <telerikGrid:RadDataGrid x:Name = "MyGrid />

    <Grid>
<Window>

this is when I get the error message:
A value of type 'RadDataGrid; cannot be added to a collection or dictionary of type 'UiElementCollection"

Is my scenario currently supported?
If yes, what else do I need to do to get this to compile?
If no, when will my scenario be supported?

Thanks
Michael
