Hello

I'm showing an icon for every item in my RadGridView. For this, I create a GridViewImageColumn the following way:

                    GridViewImageColumn imgCol = new GridViewImageColumn();         
            imgCol.ImageStretch = System.Windows.Media.Stretch.None;         
            imgCol.ImageWidth = 16;         
            imgCol.ImageHeight = 16;         
            imgCol.DataMemberBinding = binding;         

The icon is 16x16px and it's set to not stretched - still it's blurry. Now I know that this probably is not a Telerik problem because this also happens in other WPF situations. But I was trying to find something like the "SnapPixelsToDevice" or "RenderOptions.SetBitmapScalingMode" property/method.

Is there any way I can make the images look better? The Telerik-TreeView seems to work perfectly without setting any property and it uses the same images.

Thanks

.Alert with long text shows crippled Window

When displaying very long text using RadWindow.Alert(myText), RadWindow displays a window with capped off right part and no Exit Button. One must kill the app to get out.

See screenshot attached.

Create DataGrid Programmatically

Hi,

I was wondering if you have some sample code, that describes creating DataGrid Programmatically (not through XAML) - Multiple columns, and each with their own CellDataTemplate and CellEditTemplate? I searched through Documentation but couldn't find it.

Thanks,

GridView

Auto-Hide/Dock two windows in Sync

I have two Docked windows on the Left and Right side of my GUI (Similar to Visual Studio: Solution Explorer on the Left, Properties on the Right). I want to do the following

1. If I auto-hide the window on the left, it should auto-hide the window on the Right as well (and vice-versa)
2. If I dock the window on the left, it should dock the window on the right as well (and vice-versa)
3. If the windows are in Auto-Hide mode, and if the user clicks on the auto-hide window on left, the auto-hide window on the right should also expand, and when lost focus. Both should hide at the same time.

Can you tell how can I do this? If possible can you point to some sample code that accomplishes this?

Also is there a event that is fired, when a pane is docked or pinned?

Grouping the same Member several times.

Hi everyone

Quick question:

Is there a way to group the same Member several times? Take a look at the following code:

    
                                    <telerik:GridViewDataColumn Header="Jahr" DataMemberBinding="{Binding datum}" DataFormatString="{}{0:yyyy}" /> 
        
                                    <telerik:GridViewDataColumn Header="Monat" DataMemberBinding="{Binding datum}" DataFormatString="{}{0:MMM}" /> 
        
                                    <telerik:GridViewDataColumn Header="Tag" DataMemberBinding="{Binding datum}" DataFormatString="{}{0:dd}" />

I would like to group by Year (Jahr) and Month (Monat). Because the Member is always "datum" (date), I only can group one at a time.
Is there a way to achieve this within or outside the RadGridView?

ThicknessConverter declaration missing in docs

Hi guys,

I think you are missing ThicknessConverter declaration in "Customizing appearance of the radial gauge" help topic.
Like:

    
            <telerik:ThicknessExpressionConverter x:Key="ThicknessConverter" />

TemplateBinding in ColumnDefinition doesn't work

I am looking at needle customization documentation topic: "Customizing appearance of the radial gauge " and the following template:

    
            <Style x:Key="TriangleNeedleTemplate" TargetType="{x:Type telerik:Needle}"> 
        
                            <Setter Property="Template"> 
        
                                <Setter.Value> 
        
                                    <ControlTemplate TargetType="{x:Type telerik:Needle}"> 
        
                                        <Grid Width="{TemplateBinding ActualWidth}" Height="{TemplateBinding ActualHeight}"> 
        
                                            <Grid.ColumnDefinitions> 
        
                                                <ColumnDefinition Width="{TemplateBinding ActualHeight}"/> 
        
                                                <ColumnDefinition Width="*" /> 
        
                                            </Grid.ColumnDefinitions> 
        
                                            <Grid.RowDefinitions> 
        
                                                <RowDefinition Height="{TemplateBinding ActualHeight}" /> 
        
                                            </Grid.RowDefinitions> 
        
                                            <Border Background="Red" /> 
        
                                            <Polygon Grid.ColumnSpan="2" Points="0,0 1,0.5 0,1 0,0" Stretch="Fill"  
        
                                                     Fill="White" /> 
        
                                        </Grid> 
        
                                    </ControlTemplate> 
        
                                </Setter.Value> 
        
                            </Setter> 
        
                        </Style>

produces templatebinding (attached) picture. Note the red rectangle that should be ActualHeight x ActualHeight big, yet it is much wider (1/2 of the grid).
However, the "should be equivalent" binding

    
            {Binding RelativeSource={RelativeSource TemplatedParent}, Path=ActualHeight}

produces the correct result (see expandedbinding picture).
Correct style:

    
            <Style x:Key="TriangleNeedleTemplate" TargetType="{x:Type telerik:Needle}"> 
        
                            <Setter Property="Template"> 
        
                                <Setter.Value> 
        
                                    <ControlTemplate TargetType="{x:Type telerik:Needle}"> 
        
                                        <Grid Width="{TemplateBinding ActualWidth}" Height="{TemplateBinding ActualHeight}"> 
        
                                            <Grid.ColumnDefinitions> 
        
                                                <ColumnDefinition Width="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=ActualHeight}"/> 
        
                                                <ColumnDefinition Width="*" /> 
        
                                            </Grid.ColumnDefinitions> 
        
                                            <Grid.RowDefinitions> 
        
                                                <RowDefinition Height="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=ActualHeight}" /> 
        
                                            </Grid.RowDefinitions> 
        
                                            <Border Background="Red" /> 
        
                                            <Polygon Grid.ColumnSpan="2" Points="0,0 1,0.5 0,1 0,0" Stretch="Fill"  
        
                                                     Fill="White" /> 
        
                                        </Grid> 
        
                                    </ControlTemplate> 
        
                                </Setter.Value> 
        
                            </Setter> 
        
                        </Style>
