DefaultImagesSrc image sizing problem

Hello.

I'm adding an image to my treeview using the "DefaultImagesSrc" property and the ImagesBaseDir property. The image displays, but significantly smaller than it should. I tried setting the height and width properties for the radtreeviewitem to be the size of the image but that didn't work. When I drop an image control onto the xaml and set it to the same image, it displays in the proper size. What am I doing wrong?

<telerik:RadTreeView Height="250" HorizontalAlignment="Left" Margin="12,32,0,0" Name="tvDirectories" VerticalAlignment="Top" Width="364" ItemsSource="{Binding ElementName=radTreeView1, Path=Background}" ImagesBaseDir="/UploadDocFromPDFWPF;component/Images/" ItemPrepared="radTreeView_ItemPrepared">

<telerik:RadTreeViewItem DefaultImageSrc="mycomputer.png"></telerik:RadTreeViewItem>

</telerik:RadTreeView>

Again, if I create a standard image control and use the same image it displays using the proper size.

RadTileView scroll and size issues (?)

Hello,

I'd like to have a few questions about RadTileView WPF control:

I need to change the size (height) of RadTileViewItem. Setting height works fine, but the area provided by owner RadTileView remains unchanged. Is there any way to change this area's size?
The mouse scroll wheel doesn't work with RadTileView placed in ScrollViewer. I haven't found any suitable property to fix this, is there one?
When I have RadTileView placed in ScrollViewer, I scroll down little bit, click any focusable control contained in a child RadTileViewItem, and then it scrolls itself the top of the RadTileView. (In other words, when any control on RadTileViewItem gets focus, it automaticaly scrolls up to RadTileView's top border). Is there any way to change this behaviour?

Thanks for every answer.

Dynamic DataTemplates

Hello, I have a RadTileView and wondered how to change the DataTemplate for the RadTilveView.ItemTemplate (header) based on the state or configuration of the RadTileView?

Example:

<DataTemplate x:Key="MinimizedHeaderTemplate">

<StackPanel Orientation="Horizontal">

<TextBlock Text="{Binding PatientName}" Width="125" Margin="14,0,0,0" />

</StackPanel>

</DataTemplate>

<DataTemplate x:Key="MaximizedHeaderTemplate">

<StackPanel Orientation="Horizontal">

<TextBlock Text="{Binding PatientName}" Width="125" Margin="14,0,0,0" />

<TextBlock Text="{Binding Age}" Width="30" Margin="14,0,0,0" />

<TextBlock Text="{Binding Protocol}" Width="100" Margin="14,0,0,0" />

<TextBlock Text="{Binding Actions}" Width="65" Margin="14,0,0,0" />

<TextBlock Text="{Binding RegTime}" Width="75" Margin="14,0,0,0" />

</StackPanel>

</DataTemplate>

Is there something I can bind the ItemTemplate to to evaluate the state of the currently selected item?

using carousel with touch screen

Hi,
I'm having a couple of problems with my touchscreen inputs.

First of all, carousel doesn't understand single touch as a mouse left button down. i can select an item with mouse but i can't do that by touching the item. I can't find the right event to handle.

Secondly, I'm trying to scroll carousel with touchscreen inputs. As you can see it in my code, there is a ScrollViewer and its isManupulationEnabled = true.

<ScrollViewer Name="scrollGallery" Grid.Row="3" VerticalAlignment="Top" Height="289" VerticalScrollBarVisibility="Hidden" HorizontalScrollBarVisibility="Visible" CanContentScroll="True" IsManipulationEnabled="True" ManipulationDelta="ScrollViewer_ManipulationDelta" ManipulationStarting="ScrollViewer_ManipulationStarting">

<telerik:RadCarouselPanel IsOpacityEnabled="True" IsScalingEnabled="True" IsSkewAngleYEnabled="True" HorizontalAlignment="Left" Height="289" Name="radCarousel" Background="{x:Null}" Width="1013">

</telerik:RadCarouselPanel>

</ScrollViewer>

However, it's scrolling too fast with the code below:

private void ScrollViewer_ManipulationDelta(object sender, ManipulationDeltaEventArgs e)

{

scrollGallery.ScrollToHorizontalOffset(scrollGallery.HorizontalOffset - (e.DeltaManipulation.Translation.X * 0.000001));

if (e.IsInertial)

{

e.Complete();

}

e.Handled = true;

}

private void ScrollViewer_ManipulationStarting(object sender, ManipulationStartingEventArgs e)

{

e.ManipulationContainer = this;

e.Handled = true;

}

Even i multiply e.DeltaManipulation.Translation.X with 0.000001, its still too fast and not smooth

I have tried RadCarousel(not panel) before this but no success with it too.

I have also tried radCarousel.LineLeft() and LineRight() methods but got the same effect.

How can i scroll it smoothly? How can i handle touch inputs as left mouse button down?

Thanks
Gokay

Help needed with labels and ticks

I'm doing a candlestick chart and the dates are overlapping when I do a short range (say a week). I'd like to rotate the labels 90 degrees. And because the date ranges are dynamic, I'd like the x axis to adapt so that it shows appropriate intervals, depending on the date range. unfortunately, I can't seem to do anything with the x axis. Example:

<telerik:ChartDefaultView>
    <telerik:ChartDefaultView.ChartArea>
        <telerik:ChartArea>
            <telerik:ChartArea.AxisX>
                <telerik:AxisX LayoutMode="Between" IsDateTime="True" LabelRotationAngle="90" StepLabelLevelHeight="40" />
            </telerik:ChartArea.AxisX> 
        </telerik:ChartArea>
    </telerik:ChartDefaultView.ChartArea>
</telerik:ChartDefaultView>

The label does not rotate.

I'd try to set this stuff in the designer, but whenever I make changes to the X Axis in the designer, it crashes the designer.
