Hallo,

I am using this code to fill the Editor With code:

 

This does not Show any result. The SyntaxEditor is initialized and editable. But the code from ShellViewModel.cs is not showing (it is correctly loaded in the reader). Also when I type keywords into the editor, they are not highlighted. The SyntaxEditor.Document.CurrentSnapshot also does show that at least something is loaded (correct lenght and linecount).

Hi Team

I am in the process of migrating our WPF App from using .NET Framework 4.7.2 to .NET Core 3.1.

Migrating From :
 - Telerik UI for WPF .NET Framework NoXaml Binaries (Version R3 2019 SP1)
 - .NET Framework 4.7.2

Migrating To :
 - Telerik UI for WPF .NET Core NoXaml Binaries (Version R3 2019 SP1)
 - .NET Core 3.1

All has gone well to far with very little code change, however we have noticed a breaking changed between the Telerik .NET Framework assemblies and the Telerik .NET Core assemblies.

It appears that when users click on a GridViewHyperlinkColumn within a RadGridView, the hyperlink no longer follows through to open up the url in the default web browser as it did before. This can be demonstrated in a very simple example.

<telerik:RadGridView.Columns>
    <telerik:GridViewDataColumn Header="Title" UniqueName="Title" DataMemberBinding="{Binding Title}" Width="Auto"/>
    <telerik:GridViewHyperlinkColumn Header="Website" UniqueName="Website" DataMemberBinding="{Binding Website}" Width="*"/>
</telerik:RadGridView.Columns>

Please can this be investigated.

     I am creating a dynamic chart with a seriesdescriptorselector that changes the type of the X-axis (DateTimeContinuous or Linear) based on user defined settings.  I am also setting a grid for the horizontal and vertical axis of the chart.  The problem I am having is that only the horizontal lines of the grid are showing up on the chart.  I get no vertical lines at all regardless of whether the horizontal axis is Linear of DateTimeContinuous.  Does the use of a series descriptor selector invalidate the grid lines for the axis?

 

Thank you

When I am adding tabs to my tabcontrol I noticed that the tabs size according to the size of the control (their parent).  Is there any way to have the tabs actually wrap onto a 2nd (or even 3rd) level?

For example: In your demo, you have an "Add Tab" button, but you can only add so many tabs....  If you keep adding tabs you will start to see that the tabs get VERY small and unreadable.  Is there a way to have them "Auto Wrap" onto a 2nd tier of some sort?  Could this be something that is thought about for future enhancements?

Thanks a bunch

We've seen a crash in our application when the RadMap control is disposed. We've only seen the crash once but have been unable to reproduce. The stack trace is as follows:

We're currently using version 2017.2.614.45. Looking at the Telerik code it seems like the mouse event handler for MapMouseLocationIndicator doesn't get detached when RadMap is disposed. Is it possible there's some race condition that allows a mouse event to be processed in MapMouseLocationIndicator after its RadMap property has been set to null (which does happen when RadMap is disposed)?

Thanks
Pete

Hi Team

 - .NET Core 3.1

All has gone well so far with very little code change, however we have noticed a breaking change between the Telerik .NET Framework assemblies and the Telerik .NET Core assemblies.

We have a custom Dictionary of built-in ChartPalettes with custom display text that is bound to a dropdown box as per the below. Users are able to select a ChartPalette from the dropdown when displaying charts.

        /// <summary>
        /// Dictionary of <see cref="ChartPalette"/>s with custom display text
        /// </summary>
        public Dictionary<string, ChartPalette> Palettes { get; private set; }

            Palettes = new Dictionary<string, ChartPalette>
            {
                {"Spring", ChartPalettes.Spring},
                {"Summer", ChartPalettes.Summer},
                {"Autumn", ChartPalettes.Autumn},
                {"Arctic", ChartPalettes.Arctic},
                {"Warm", ChartPalettes.Warm},
                {"Cold", ChartPalettes.Cold},
                {"Crystal", ChartPalettes.Crystal},
                {"Flower", ChartPalettes.Flower},
                {"Fluent", ChartPalettes.Fluent},
                {"Forest", ChartPalettes.Forest},
                {"Grayscale", ChartPalettes.Grayscale},
                {"Green", ChartPalettes.Green},
                {"Ground", ChartPalettes.Ground},
                {"Lilac", ChartPalettes.Lilac},
                {"Material", ChartPalettes.Material},
                {"Office 2013", ChartPalettes.Office2013},
                {"Office 2016", ChartPalettes.Office2016},
                {"Pastel", ChartPalettes.Pastel},
                {"Rainbow", ChartPalettes.Rainbow},
                {"Visual Studio 2013", ChartPalettes.VisualStudio2013},
                {"Visual Studio 2019", ChartPalettes.VisualStudio2019},  // Does not work in Telerik .NET Core assemblies
                {"Windows 8", ChartPalettes.Windows8},
            };

The issue is that the VisualStudio2019 ChartPalette (from Telerik.Windows.Controls.ChartView) throws the below exception when using the Telerik .NET Core assemblies. This does not occur when using the Telerik .NET Framework assemblies.

System.IO.IOException: 'Cannot locate resource 'visualization/palettes/resources/visualstudio2019.xml'.'

StackTrace:
   at MS.Internal.AppModel.ResourcePart.GetStreamCore(FileMode mode, FileAccess access)

   at Telerik.Windows.Controls.ChartView.ChartPalettes.get_VisualStudio2019()

I can confirm we have ALL Telerik .NET Core assemblies being referenced in our project including the Theme assemblies and styles. If we remove the VisualStudio2019 ChartPalette, it works perfectly without any issues.

Please can this be investigated.

We are having an issue with the CellStyleSelector randomly changing the style when scrolling left and right in the GridView.

We have it narrowed down to our comparison in the StyleSelector code. We need to compare the cell value to the Min and Max columns to see if it is within the range. If it is, set the style to Valid, if not set it to Invalid.

This works on loading of the grid, but the scrolling causes it to glitch.

Code where the value of comparison (cell) changes and causes glitch:

 

Code example using a fixed value of comparison (cell) and does not glitch:

 

We have poured over these forums and every example for StyleSelector uses a fixed value for comparison. 

We have applied this concept to the NegativeStyleSelector.zip in this forum and it also glitches: https://www.telerik.com/forums/apply-cellstyleselector-in-code-behind

Any help would be appreciated!

Thanks!

I am getting a strange error on a customer PC with RadGlyph's.  They have a vanilla Win7 box with .Net 4.5.1, any idea what might cause this?  It works fine on my Win7 machine so I'm not sure where to look.

 

When user clicks on X, I want to check whether there are any unsaved changes in the page. 

I have isNotSaved Property which tells me that. 

Now, if there are any unsaved changes, I want to show Alert window(which is in place) to confirm by user to close pane or not.

If user says Yes, I want to close, If not I dont want to close.

How can I implement this in Pure MVVM ?

How to get the contents of a row (Model) simply by mousing over the row? I'm trying to cache the row, that is, it's underlying model when a user mouses over the row.
