Hi,
When using certain column names in a Telerik WPF grid, the corresponding values are not being displayed correctly. The issue occurs when attempting to show data in the grid with the following column names :

Observed Behavior :

After binding the data object to the grid, some values are not visible for specific column names. This issue appears to be related to column names that contain special characters such as periods (".") and spaces. Consequently, users cannot view the complete dataset, leading to data misinterpretation.

Additional Notes:

This issue severely impacts the usability of our application, as users rely on the accurate display of data in the grid. We use dynamic objects because the user generates the SQL requests. Is it a bug? There is any workaround or alternative approach using dynamic objects that would allow us to display the data correctly in the grid, we would be grateful for your guidance on implementing it ?

Attached you'll find a simplified example of how to reproduce the bug and a screenshot.

If you require any additional information or assistance in reproducing the bug, please do not hesitate to reach out. We are eager to see this issue addressed as soon as possible.

Best regards,

Hi,

I currently am using a RadMenuItem to show one particular Icon for example the Whatsapp logo.

When I hover over the RadMenuItem I would like the icon to change to another version (white) which will be more visible due to our RadMenuItem mouse over having a darker background.

The code below is showing the original logo but the IsMouseOver trigger does not appear to be working.

Here is my code:

MainWindow.Xaml

                        <telerik:RadMenuItem Height="30" 
                                             Command="{Binding EmailSupportCommand}"
                                             FontSize="14" IconColumnWidth="30" Header="Email info@.com"
                                             >
                            <telerik:RadMenuItem.Icon>
                                <Image>
                                    <Image.Style>
                                        <Style TargetType="{x:Type Image}">
                                            <Setter Property="Source" Value="..\..\Auxiliary\Resources\64x64\dark\email.png" />
                                            <Style.Triggers>
                                                <DataTrigger Value="True" Binding="{Binding RelativeSource={RelativeSource AncestorType=telerik:RadMenuItem}, Path=IsMouseOver}">
                                                    <Setter Property="Source" Value="..\..\Auxiliary\Resources\64x64\light\email.png" />
                                                </DataTrigger>
                                            </Style.Triggers>
                                        </Style>
                                    </Image.Style>
                                </Image>
                            </telerik:RadMenuItem.Icon>
                        </telerik:RadMenuItem>

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

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

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,
