I have added a wizard control in my WPF MVVM project.

On one page of the wizard I have a combobox that binds to a property from a model (MVVM)

After I moved to the next page, the value in that combobox is reset to NULL.

How do I preserve values selected in previous pages of the wizard

Thanks

Miroslav

Hi,

I'm using the RadSyntaxEditor with the XmlTaggers. 

Unfortunately, when I switch from Light theme to Dark theme, the background color change in black but the text don't became white.

So we haven't a lot of contrast between background and text.

I use implicit style :

                <ResourceDictionary Source="/Telerik.Windows.Themes.VisualStudio2013;component/Themes/Telerik.Windows.Controls.SyntaxEditor.xaml"/>

I try to force it :  <telerik:RadSyntaxEditor x:Name="SyntaxEditor" Margin="10,10,0,10" telerik:StyleManager.Theme="VisualStudio2013">.

Nothing change. You will find attached two pictures describing the situation.

Oh, and I'm using Telerik 2020.1.115.45.

 

Regards,

Florian

I am adding tooltip to my datagrid headers this way:

                <telerik:GridViewDataColumn DataMemberBinding="{Binding Number}" 
                                            Width="40" 
                                            TextAlignment="Right">
                    <telerik:GridViewDataColumn.Header>
                        <TextBlock Text="#" 
                                   ToolTipService.ToolTip="Number of the match"/>
                    </telerik:GridViewDataColumn.Header>
                </telerik:GridViewDataColumn>

The problem is I also has this defined for my grid:

            <telerik:RadGridView.SortDescriptors>
                <telerik:SortDescriptor Member="StartDate" SortDirection="Ascending"/>
                <telerik:SortDescriptor Member="StartTime" SortDirection="Ascending"/>
                <telerik:SortDescriptor Member="PitchName" SortDirection="Ascending"/>
            </telerik:RadGridView.SortDescriptors>

With indirect styling, the header now does not change the text color and thus fade away behind the selected color of the header... how can I style the column to avoid this effect?

We have two situations:  one in which a ManipulationAdorner shows up, and one in which it does not.  I've determined that the sole difference, as far as I can tell, is the Visibility property on ManipulationAdorner itself.  In the one case, the Visibility is "Visible"; in the other, "Collapsed".

I see no other differences in this situation, including with DataContext and the styles/templates.  That is, in both cases, the DataContext has the same property values, and, in both cases, the styles/templates used are the same.

Visibility is being set locally, which means directly on the object either in xaml or in code.  We don't set Visibility directly ourselves, so I'm wondering whether there is logic internal to Diagram or ManipulationAdorner that sets the Visibility?  If so, what are the conditions that result in Visible vs Collapsed, please?  My hope is that I can work backwards from there to figure out how we're triggering the Collapsed state.

Thank you!

H, I show a balloon tip with a text that is larger than the default size of notification area and I can't see all the text. I tried also with Configurator Example with the same result.
Is there a way to show a large text in balloon tip?
Thank you 

Luigi

Hi, 

I'm trying to use your DragDropManager to be able to reorder my lists as I wish. 

And I have to congratulate you because it's very easy to use when you just want to reorder a list.

Unfortunately, I would like to execute a method after each drag and drop action.

I tried to bind a command on the Drop event but the list order wasn't modified yet. 

So I found the telerik:DragDropManager.DragDropCompleted which seemed perfect but I didn't succeed to use it.

I tried to respect MVVM pattern with the telerik:EventToCommandBehavior, System.Windows.Interactivity.EventTrigger but it didn't work.

I also tried to use it in the code-behind (xaml.cs) but nothing works.


Can you help me to understand what's the problem ?

And can you also help me to find a way to resolve my problem within respect the MVVM pattern ?


Thanks in advance for your time and your answer.

With every new release, we recompile the libraries so that we can set the application name to meet licensing requirements.

However, with 2023 R3, the compilation is failing due to four instances of a call to FunctionBase.LinearInterpolate in BrushRenderer.cs which leads to the following compilation error:

Fixed\UI\BrushRenderer.cs(233,50): error CS0117: 'Telerik.Windows.Documents.Fixed.Model.Common.Functions.FunctionBase' does not contain a definition for 'LinearInterpolate'

The LinearInterpolate method is definitely not defined in FunctionBase, would appreciate any available help on this.

Hi Telerik,

I know there is a way to print the Gantt View with data hidden behind the horizontal scrollbar, which I have worked 5 years ago.

But I'm not sure that can be done in RadGridView.

I mean I'm having 10 columns in RadGridView, in which 2 columns are scrolled inside horizontal scroll bar.

I want to print the rows in the visible area with all the 10 columns. Please help me if there is any way to achieve this.

 

Thanks and Regards,

Muhammad Azhar Shah

When using version 2023.2.718 targeting .NET 6.0 on VS 2022, I tried to create a RadCartesianChart as described here: https://docs.telerik.com/devtools/wpf/controls/radchartview/multiple-chart-series

The PointSeries and BarSeries are recognized as expected, but LineSeries generates errors that make the designer complain about invalid markup:

The program builds and runs fine.

Anyone have a clue as to what is happening here?

For a home project I'm working on, I have paid upto version R3 2021 SP2.  Will this version work with Visual Studio 2022 and can I use .NET 7 with this version?

If not, what is the most current version of Telerik UI WPF that does support Visual Studio 2022?

What is the most current version of Telerik UI WPF that supports .NET 7?

Thanks, Rob.
