Hi,

I would like to create and use a converter to change the background of a single selected button among the three buttons available. I don't want to handle a click event of the buttons and handle it from code behind and so tried different ways to create the converters, however it didn't work. Below I am providing a sample of my scenario. Any help would be greatly appreciated. Thank you.
 

<StackPanel Grid.Row="0" HorizontalAlignment="Center" x:Name="FirstRowControl" Orientation="Horizontal" Margin="232,0,233,0">
<telerik:RadButton Name="btn1" FontWeight="SemiBold" Margin="5" Content="Button 1" HorizontalAlignment="Left" VerticalAlignment="Top" Width="120" Height="25" BorderBrush="Black" Command="{Binding UpdateTabCommand}" >
<telerik:RadButton.CommandParameter>
<models:Tabs>Button1</models:Tabs>
</telerik:RadButton.CommandParameter>
</telerik:RadButton>
<telerik:RadButton Name="btn2" FontWeight="SemiBold" Margin="5" Content="Button 2" HorizontalAlignment="Left" VerticalAlignment="Top" Width="100" Height="25" BorderBrush="Black" Command="{Binding UpdateTabCommand}" >
<telerik:RadButton.CommandParameter>
<models:Tabs>Button2</models:Tabs>
</telerik:RadButton.CommandParameter>
</telerik:RadButton>

<telerik:RadButton Name="btn3" FontWeight="SemiBold" Margin="5" Content="Button 3" HorizontalAlignment="Left" VerticalAlignment="Top" Width="180" Height="25" BorderBrush="Black" Command="{Binding UpdateTabCommand}" >
<telerik:RadButton.CommandParameter>
<models:Tabs>Button3</models:Tabs>
</telerik:RadButton.CommandParameter>
</telerik:RadButton>
</StackPanel>

Code in the VM:
 
public DelegateCommand<Tabs?> UpdateTabCommand
{ get; }

public Tabs SelectedTab
{
get { return base.GetProperty<PedpTabs>(defaultValueFactory: () => Tabs.Button1); }
set { base.SetProperty(value); }
}

public enum Tabs
{
Button1,
Button2,
Button3
}


public ClassVM()
{
UpdateTabCommand = new DelegateCommand<Tabs?>(OnChangeTabExecute);
}


private void OnChangeTabExecute(PedpTabs? selectedTab)
{
this.SelectedTab = selectedTab ?? Tabs.StateChanges;
}

protected override void OnPropertyChanged(string propertyName)
{
base.OnPropertyChanged(propertyName);

switch (propertyName)
{
case nameof(SelectedTab):
OnTabChanged();
break;
}
}

private void OnTabChanged()
{
switch (SelectedTab)
{
case Tabs.Button1:
    MessageList = Messages2080;
    break;

case Tabs.Button2:
MessageList = Messages2088;
break;
case Tabs.Button3:
MessageList = Messages2010;
break;
}
}

Thanks, Chand

Hi, I have a hierarchy that looks something like this:

<RadLayoutControl>

  <LayoutGroup>

    <LayoutExpanderGroup>
      <SomeControl/>
    </LayoutExpanderGroup>

    <LayoutExpanderGroup>

      <RadGridView/>

    </LayoutExpanderGroup>

  </LayoutGroup>

</RadLayoutControl>

My RadGridView has many columns and rows and so causes the entire <RadLayoutControl> to scroll.  Is it possible to configure this view so that only the <LayoutExpanderGroup> that contains the <RadGridView> will scroll?

Any help would be appreciated.

Hi,

I'm using the CloudUpload in my application, and I was wondering if there was anyway to update the tooltip language resource of the RadCloudUploadListItem Close Button (I joined a screenshot of the tooltip I'm talking about). I wasn't able to find it in the xaml style template.

Could someone help me with this issue?

Thank you,

I want to hide only the horizontal or vertical scrollbar. Is that possible ?

The only solution I found now is the following style :

The problem here is that it is hiding both Scrollbars. Is there a option where I can decide which one I want to hide ?

How can I use correctly the above xaml in code behind ? 

This is not working :

I am using RadSpellChecker to spell check a WPF TextBox.  In a different area of my application, I am using RadRichTextBox and I have a custom dialog for spell checking.  When I spell check the WPF TextBox, I get the built-in spell checking dialog instead of my custom dialog.  Is there a way to also use the custom dialog when spell checking a WPF TextBox?

I have created a simple project to start working RadImageEditor.

The problem is that my image doesn't display in the editor at all. Even when I execute the Open command of the ImageEditor.

I'm not sure if the ImageEditor isn't visible or the image doesn't get loaded inside of it.

Since I'm not allowed to attach a zip file I'll add the code of each class of my project:

MainWindow.Xaml:

<Window x:Class="WpfApp4.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
        mc:Ignorable="d"
        Title="MainWindow" Height="450" Width="800">
<Grid>
<Grid.RowDefinitions>
<RowDefinition />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<telerik:RadImageEditor HorizontalAlignment="Stretch" VerticalAlignment="Stretch" ScaleFactor="0" x:Name="ImageEditor" Background="Red"/>
<Button Click="Button_Click" Content="Load picture" Grid.Row="1" />
</Grid>
</Window>

MainWindow.Xaml.cx:

namespace WpfApp4
{
    /// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();

            ImageExampleHelper.LoadSampleImage(this.ImageEditor, "RadImageEditor.png");
        }

        private void Button_Click(object sender, RoutedEventArgs e)
        {
            this.ImageEditor.Commands.Open.Execute(this.ImageEditor);
        }
    }
}

ImageExampleHelper.cs:

    public class ImageExampleHelper
    {
        public static void LoadSampleImage(RadImageEditor imageEditorUI, string image)
        {

            Stream stream1 = File.OpenRead("D://test image//radImageEdito.png");
            string extension = Path.GetExtension("D://test image//radImageEdito.png").ToLower();

            IImageFormatProvider formatProvider = ImageFormatProviderManager.GetFormatProviderByExtension(extension);
            if (formatProvider != null)
            {
                imageEditorUI.Image = formatProvider.Import(stream1);
                imageEditorUI.ApplyTemplate();
                imageEditorUI.ScaleFactor = 0;
            }
            stream1.Close();
        }
    }

Thanks!
