We were using a standard Window object as the parent for our MainWindow. All was good. Then we wanted to do theming...couldn't do it easily, we found we needed to change to telerik:RadWindow. That's when everything went.....bad. No more window icons, no more task bar icon, no more showing up in taskbar. We've been able to figure out msot things and add more code to "fix" what we thought should be part of the default behaviour.

Then this morning my boss uses the mouse to try to change a value in a RadComboBox.....nope. Huh? I must have done something wrong? I don't think so. The change is in git and linked to the exact date we changed from Window to RadWindow..

How are you supposed to get mouse selections to work with a RadComboBox contained in a RadWindow?

Hi Team,

We are using RadStepProgressBar in our project, and we would like to change the selected color from Yellow to Blue. However, we have not been able to find a solution.

Here is the current XAML code:

<telerik:RadStepProgressBar  
    Background="AliceBlue"
    VerticalAlignment="Top" 
    x:Name="stepProgressBar" 
    Grid.Row="0" 
    TrackFill="LightGreen" 
    SelectedIndex="{Binding SelectedIndex, Mode=TwoWay}"
    ItemsSource="{Binding OrderSteps}" 
    DisplayMemberPath="Name" 
    AnimationDuration="0.6"
    Margin="0 0 0 0">
    <telerik:RadStepProgressBar.ItemContainerStyle>
        <Style TargetType="telerik:RadStepProgressBarItem">
            <Setter Property="TextBlock.TextAlignment" Value="Center" />
            <Setter Property="TextBlock.Foreground" Value="White" />
            <Setter Property="ShapeStroke" Value="Black" />
            <Setter Property="Background" Value="DarkSlateGray" />
            <Setter Property="TextBlock.TextAlignment" Value="Center" />
        </Style>
    </telerik:RadStepProgressBar.ItemContainerStyle>
</telerik:RadStepProgressBar>

Could you please assist us in changing the selected color to Blue?

Thank you.

This code behind does not work for importing files that are read only access. No error pops up, just a blank spreadsheet opens up

using (Stream input = new FileStream(this.ExcelDocumentSource, FileMode.Open, FileAccess.Read))
{
    this.Workbook = new XlsxFormatProvider().Import(input);
    //this.Workbook.Protect("telerik");
}

Thanks,

Hello,

I'm wondering if there is a way to set a fixed height to the bars in a barseries. For example, instead of the bars changing height in the following example, I'd like them to stay up with a fixed height.

The desired outcome would look something like this:

The xaml I used fort the example is this:

<telerik:RadCartesianChart>

    <telerik:RadCartesianChart.Series>
        <telerik:BarSeries ShowLabels="False"
                           CategoryBinding="Category"
                           ValueBinding="Value">

            <telerik:BarSeries.DataPoints>
                <telerik:CategoricalDataPoint Category="Apples" Value="20"/>
                <telerik:CategoricalDataPoint Category="Bananas" Value="28"/>
                <telerik:CategoricalDataPoint Category="Oranges" Value="17"/>
                <telerik:CategoricalDataPoint Category="Strawberries" Value="30"/>
            </telerik:BarSeries.DataPoints>
        </telerik:BarSeries>
    </telerik:RadCartesianChart.Series>

    <telerik:RadCartesianChart.HorizontalAxis>
        <telerik:LinearAxis x:Name="horizontalAxis1"/>
    </telerik:RadCartesianChart.HorizontalAxis>
    
    <telerik:RadCartesianChart.VerticalAxis>
        <telerik:CategoricalAxis/>
    </telerik:RadCartesianChart.VerticalAxis>


</telerik:RadCartesianChart>

Is this possible using the BarSeries? Any help is appreciated.

Thank You,

Hi,

I would like to have the DataFormComboBoxField  behave the same way as the Edit mode: Editable, Read-Only and Auto Complete ad in your demo application. But when I set it to readonly it is disabled.

My code:

e.DataField = new DataFormComboBoxField()
{
    ItemsSource = _componentsDS.ComponentKeyWords,
    SelectedValuePath = "KeyWordId",
    DisplayMemberPath = "Abbreviation",
    DataMemberBinding = new Binding("KeywordId") { Mode = BindingMode.TwoWay },
    IsComboboxEditable = true,
    IsReadOnly = true,
    Label = "Keyword"
};

The example in your application:

Kind regards,

Johan

Is the source for this app available?  If so, where?  I don't necessarily need the source, but I'd like to know how the stuff marked in red (I wish I knew the correct names/terminology) is done in a WPF app.

Alternatively, is there a different example that shows it?

I'm evaluating Telerik's UI for WPF and simply don't have the knowledge nor the time to learn the GridView thoroughly.  I have to make a decision between Telerik and a competitor very soon.

The question is about filtering.  I like the filtering in the Telerik grid, with the funnel icon.  However, my client is familiar with a different experience, and prefers it.  Specifically, the client would like a line between the column headers and the data (basically a textbox in each column) where the user could simply type and the grid would automatically filter using a "contains" (simple concept, but not so easy for me to describe).  Is that something that could be done with Telerik's grid?  Can it be done with configuration, or would it require custom coding?  Ideally I'd love to see an example (GitHub)?

Thanks in advance.

Hello,

I'm trying to see if there is a way to align a chart label so that it shows up inside the bar but left aligned. Here is what I have right now:

I'd like for the numbers to be left aligned but still in the bar:

Here is the xaml I have:

This is about the RadSplitButton in UI for WPF. I use the Windows 8 theme.

RadSplitButton closed:

RadSplitButton opened:

I want to change that blue color (#25A0DA) to something that's not associated with the theme. I already change the colors of the Windows8Palette and the blue default color seems to be the AccentColor - I don't want to change the AccentColor, though (I set that to something different, which looks great everywhere except the RadSplitButton).

I already added the control template for RadSplitButton and it does work - when I change values I see those in the UI. But which value do I have to change to change the color when RadSplitButton was opened? I couldn't find it.

The XAML sample from the screenshots:

        <telerik:RadSplitButton Content="This is a RadSplitButton" HorizontalAlignment="Left" Margin="80,70,0,0" VerticalAlignment="Top">
            <telerik:RadSplitButton.DropDownContent>
                <StackPanel>
                    <telerik:RadButton Content="This is a RadButton" HorizontalContentAlignment="Left"/>
                    <telerik:RadButton Content="This is a RadButton (2)" HorizontalContentAlignment="Left"/>
                </StackPanel>
            </telerik:RadSplitButton.DropDownContent>
        </telerik:RadSplitButton>

I have a class wrapper for working with the Telerik zip library. Since I updated my project to work with a new version (Q2) there started a problem with zip files. I can create a zip file protected with some password, but I cannot read or update it, may some problem is with decryption operation, which also occurs in default Windows Explorer and 7Zip application.

There's a code that I use for the wrapper:

public void Create(string archivePath, string? password = null)
{
    using var baseStream = fileSystem.FileStream.New(archivePath, FileMode.Create, FileAccess.ReadWrite);
    using var archive = ZipArchive.Create(baseStream, null, compressionSettings, GetEncryptionSettings(password));
}

public void SerializeEntry<T>(string archivePath, string entryName, T entry, string? password = null)
{
    using var baseStream = fileSystem.FileStream.New(archivePath, FileMode.Open, FileAccess.ReadWrite);
    using var archive = ZipArchive.Update(baseStream, null, compressionSettings, GetDecryptionSettings(password));
    archive.GetEntry(entryName)?.Delete();
    XmlInOut<T>.SaveToStream(archive.CreateEntry(entryName).Open(), entry);
}

public T DeserializeEntry<T>(string archivePath, string entryName, string? password = null)
{
    using var baseStream = fileSystem.FileStream.New(archivePath, FileMode.Open, FileAccess.ReadWrite);
    using var archive = ZipArchive.Read(baseStream, null, compressionSettings, GetDecryptionSettings(password));
    return XmlInOut<T>.LoadFromStream(archive.GetEntry(entryName).Open());
}
