Hello.

 

I want to customize the header for the tab control.

1.(red) I want to change or delete the color of the underlined line for the selected item.

2(blue). I want to change the mouse hover background color of tab items.

3.(orenge). There is a "+" button after the menu with AdditionalContent. I also want to put a "*" in front of the menu.

 

Some old data used navigationtabcontrol, so I couldn't find a recent example.

I'd appreciate it if you could tell me how to style each of these.

Thanks.

We have a RadPane styled with IsHidden bound to a viewmodel property.

 <Style x:Key="PaneStyle" TargetType="{x:Type telerik:RadPane}">
   <Setter Property="CanUserClose" Value="False" />
   <Setter Property="CanFloat" Value="False" />
   <Setter Property="CanUserPin" Value="False" />
   <Setter Property="ContextMenuTemplate" Value="{x:Null}" />
   <Setter Property="IsPinned" Value="True" />
</Style>
<Style x:Key="PaneXStyle" TargetType="{x:Type telerik:RadPane}" BasedOn="{StaticResource PaneStyle}">
     <Setter Property="IsHidden" Value="{Binding HidePaneX}" />
</Style>
 

with the styles used like so:

<telerik:RadDocking AllowUnsafeMode="True">
   <telerik:RadDocking.DocumentHost>
     <telerik:RadSplitContainer>
       <telerik:RadPaneGroup>
        <telerik:RadPane Style="{StaticResource PaneStyle}" Header="Some Panes">
          <telerik:RadDocking AllowUnsafeMode="True">
            <telerik:RadDocking.DocumentHost>
              <telerik:RadSplitContainer>
                <telerik:RadPaneGroup>
                  <telerik:RadPane Style="{StaticResource PaneXStyle}" Header="PaneX">
       ......
 

After updating recently to v. 2021.1.325, we get the following exception.  We'd previously been on a very old version (2015 q1 sp1).

For the time being, we instead bind IsEnabled to our VM property, but we'd like to be able to hide these panes again, please.

Additionally, the exception doesn't happen if the pane happens to be visible when the application starts; rather, it only happens if the pane is out of view (one of the other panes in the top-level Docking is foremost) and we browse to it later.  It is still docked during this time.

 

Is this a bug for which we should file a report?  Is there a different or better way to do this?

I have read the Telerik Article on Localization with UI for WPF but I am using the Telerik NuGet server and the assemblies it provides to not appear to match what is in that article.   

My application...

  • uses Telerik binaries *with* Xaml
  • uses the Telerik NuGet server to obtain its DLLs
  • has both English and French translations.

I see that the Telerik NuGet Server appears to provide two separate  assemblies related to each language.  For example, I see the following two assemblies with the ".fr" suffix for French

Telerik.Windows.Controls.for.Wpf.fr
Telerik.Windows.Controls.for.Wpf.Xaml.fr

What is the difference between these two?  Should I include them BOTH with my application or just one of them?

I am trying to display the data points in a ScatterLineSeries when the user clicks a button using the following code:

private void ShowDataPointsButton_Click(object sender, RoutedEventArgs e)
{
    foreach (var series in CartesianChart.Series)
    {
        if (series is ScatterLineSeries)
        {
            series.DefaultVisualStyle = Application.Current.Resources["DataPointStyle"] as Style;
        }
    }
}

(where `CartesianChart` is a `RadCartesianChart` control)

The style definition is as follows:

<Style x:Key="DataPointStyle" TargetType="{x:Type Path}">
    <Setter Property="Height" Value="5" />
    <Setter Property="Width" Value="5" />
</Style>

(I am using a palette to style the chart; hence the missing definition for `Fill`)

But for some reason, I have to follow these steps in order to see the data points styled:

  1. Press the `ShowDataPointsButton` button
  2. Zoom into the chart
  3. Press the `ShowDataPointsButton` button
  4. Press the `ShowDataPointsButton` button again

I have tried the following options to fix this issue:

  1. Remove the series from the chart -> Apply the style -> Add the series back into the chart
  2. Apply the style -> Force a redraw manipulating the zoom level on the chart
  3. Using the dispatcher associated with the series to force a redraw
  4. Using Application.Current.Dispatcher to apply the style with Render priority
  5. Binding a property to `DefaultVisualStyleProperty` and setting its value when user clicks the button

But in all these instances (except option 5 where the trial with binding did not work at all), I have to follow the steps mentioned up above to see the data points in the chart.

Could you please guide me on what is the right way to apply `DefaultVisualStyle` for a ScatterLineSeries in runtime from C# code-behind?

I'm trying to create a custom column for my RadGridView, where upon editing the cell, an appropriate control is shown - A combobox for a boolean or an enumeration, a RadMaskedTextInput for text, and a RadMaskedNumericInput for numeric values.

I'm using the RadMaskedNumericInput as I need to set maximum and minimum values, and I've seen the samples of how to set minimum & maximum values for the RadMaskedNumericInput when in xaml, by using something like:

 <telerik:RadMaskedNumericInput maskedInput:MaskedInputExtensions.Minimum="0" /> 

However, as I'm creating the control dynamically in the Custom Column class, I can't find a way of doing the same in code? i.e. as part of creating the control using "RadMaskedNumericInput numericTb = new RadMaskedNumericInput();" I also have the same issue in trying to set the Min & Max length extensions for the RadMaskedTextInput control. 

Thanks

Hello to all,

I have a new problem in the latest version of Telerik UI for WPF with the RadGridView control.

I get sporadic a NullReferenceException when I work with the control. Unfortunately it is not reproducible.

Hopefully someone can help me. Thank you in advance.

Here is the call stack of the exception:

The columns will be added programmatically in code behind:

                m_dgOperands.Columns.Clear();
                selectedColumn = null;

                //Add the known columns

                {
                    Header = "#",
                    DataMemberBinding = new Binding("ID"),
                    IsReadOnly = true,
                    CellStyleSelector = new StepStyleSelector(),
                });

                m_dgOperands.Columns.Add(new GridViewDataColumn()
                {
                    Header = "Step",
                    DataMemberBinding = new Binding("Name"),

                    CellStyleSelector = new StepStyleSelector(),
                    MinWidth = 150,
                });

                columnGroupName = new GridViewDataColumn();

                columnGroupName.CellStyleSelector = new StepStyleSelector();
                m_dgOperands.Columns.Add(columnGroupName);

                m_dgOperands.Columns.Add(new GridViewDataColumn()

                    Width = 3,
                    MaxWidth = 3,
                    IsResizable = false
                });

                    CheckColumnGroup(zone, item);
                    m_dgOperands.Columns.Add(item);

I did all I can Still I cannot take away the line spacing after hitting  "Enter", I could not get it working  (looks like the DocumentInheritsDefaultStyleSettings  is interfering?)

I have uploaded a sample project (that tells the behavior) as well.

 

Please find the code I used below.

                                <telerik:RadRichTextBox x:Name="custNotesRichTextBox"
                                                        Grid.Row="0"
                                                        DocumentInheritsDefaultStyleSettings="True"                                                     
                                                        AcceptsTab="True"
                                                        AcceptsReturn="True"                                                         
                                                        ScrollViewer.VerticalScrollBarVisibility="Auto"
                                                        HorizontalScrollBarVisibility="Hidden"                                                        
                                                        IsSpellCheckingEnabled="True"
                                                        Language="en-US"
                                                        IsContextMenuEnabled="True"                                                        
                                                        Margin="0"
                                                        VerticalScrollBarVisibility="Hidden">
                                    <telerik:RadRichTextBox.Document>
                                    <telerik:RadDocument LineSpacing="0" LineSpacingType="AtLeast" ParagraphDefaultSpacingAfter="0" ParagraphDefaultSpacingBefore="0" >
                                        <telerik:Section>
                                                <telerik:Paragraph LineSpacing="0" LineSpacingType="AtLeast" SpacingBefore="0" SpacingAfter="0" AutomaticSpacingBefore="False" AutomaticSpacingAfter="False" >
                                                <telerik:Span  Text=" "/>
                                            </telerik:Paragraph>
                                        </telerik:Section>
                                    </telerik:RadDocument>
                                    </telerik:RadRichTextBox.Document>
                                    </telerik:RadRichTextBox>

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
