Hi,

When I am using the following code to show a splash screen using the RadSplashScreenManager, with StartupLocation = null, only the top left corner of the window is centered on the screen. I have the same behavior without customizing the SplashScreenDataContext :

            var splashScreenDataContext = (SplashScreenDataContext)RadSplashScreenManager.SplashScreenDataContext;
            splashScreenDataContext.ImageHeight = 300.0;
            splashScreenDataContext.ImageStretch = Stretch.Uniform;
            splashScreenDataContext.ImagePath = "/MyAssembly;component/Resources/MyImage.png";

            RadSplashScreenManager.Show();

In the sample, your are using hard coded sizes (260 and 160) to calculate the StartupLocation of the splash screen :

        private void ShowSplashScreen()
        {
            this.timer.Start();
            Mouse.OverrideCursor = Cursors.Wait;
            this.splashScreenDataContext = RadSplashScreenManager.SplashScreenDataContext as SplashScreenDataContext;
            this.splashScreenDataContext.ImagePath = "/SplashScreen;component/SplashScreen.png";
            this.splashScreenDataContext.IsIndeterminate = false;
            this.splashScreenDataContext.Content = "Loading... 0%";
            this.parentWindow.CanMove = false;
            this.parentWindow.IsEnabled = false;
            if (this.parentWindow.WindowState != System.Windows.WindowState.Maximized)
            {
                var x = this.parentWindow.Left + this.parentWindow.ActualWidth / 2 - 260;
                var y = this.parentWindow.Top + this.parentWindow.ActualHeight / 2 - 160;
                RadSplashScreenManager.StartupPosition = new System.Windows.Point(x, y);
            }

            RadSplashScreenManager.Show();
        }

Hard coding the sizes of the window is obviously not ideal. Instead, the splash window should act like any Window with the property SizeToContent="WidthAndHeight".

Can you help ?

Hello,

I have some troubles for getting the RadDatePicker working as expected, while using the propertiy 'DisplayDateStart'. Here my code:

At the start, when I select a date from the first RadDatePicker (valid from), the other one is working correctly (see the ok.png). But if I choose another date (minor to the previous one) some date are still greyed out on the second control (Valid To, see the not_ok.png --> the date 1,2,3,4,5 cannot be selected). I'm not able to reproduce the same error on the other side, changing the valid to control. 

Edit:

I found that these controls inherit implicity from a style that has:

        <Setter Property="SelectableDateStart"
                Value="{StaticResource MinimumAllowedDate}" />
        <Setter Property="DisplayDateStart"
                Value="{StaticResource MinimumAllowedDate}" />

where MinimunAllowedData is equal to     <system:DateTime x:Key="MinimumAllowedDate">1/1/1900</system:DateTime>

Removing the SelectableDateStart solve the issue. Still not sure why is this behavior happening?

If I change the control in this way

I still get the error.

Are you aware of this behaviour? Or am I missing something? Thank you.

Hello everyone,

can anyone post me a simple xaml code snipset to add CheckBox items into a ComboBox?

I searched in the forum but there is no simple example.

I thought something like this

<telerik:RadComboBox>
                            <telerik:RadComboBox.ItemTemplate>
                                <DataTemplate>
                                    <kzv:KzvCheckBox/>
                                </DataTemplate>
                            </telerik:RadComboBox.ItemTemplate>
                            <telerik:RadComboBoxItem Content="Test"/>
                        </telerik:RadComboBox>

But the CheckBox is still missing

Thanks for your help.

I am using CartersianChart and have a vertical BarSeries attached to it.  Each bar in the series represent a numerical amount. I want to display a horizontal line across the chart at a particular amount so that it can quickly be seen which bars are above and which are below that amount. I'm looking for something similar to the red line in the attached image. Any insight you could give will be greatly appreciated.

Thanks,

George

Hello.

How do I set up the expanded configuration of the Treeview middle model only?

<telerik:RadTreeView.Resources>
	<Style TargetType="telerik:RadTreeViewItem" BasedOn="{StaticResource RadTreeViewItemStyle}">
		<Setter Property="IsExpanded" Value="True"/>
	</Style>
</telerik:RadTreeView.Resources>

This is true for all of the lower layers.

When I first opened it, I only want to open it up to the middle level. (Attach an image)

Thanks.

Hello

I've attached an example, and the ContentTemplateSelector will cause a designer exception.
Build and debug works fine.

First. In using navigation I want to control everything by binding in MainWindowViewModel.
Each UserControl is a different screen.
However, the combo box and button are the same.
So, when you move the view, the data should remain the same.

This is actually implemented using RadTabControl.
Tab control does not have a hierarchy, so I want to use navigation.

[TabControl Sample.xaml] : This is automatically set to the datacontext in the window if you do not set the datacontext in the usercontrol.

<telerik:RadTabItem Header="View 1" Width="60" >
    <telerik:RadTabItem.Content>
        <userControl:UserControlView/>
    </telerik:RadTabItem.Content>
</telerik:RadTabItem>

Second. In the current source, Hierarchy 1 and 2 are set to View(UserControlMain - This is not really necessary.).
I want to open only the hierarchy by clicking on the hierarchy. (view maintained, only IsExpanded)

However, if you don't put a View in the selector, an exception will be thrown.
"Must disconnect specific child from current parent Visual before attaching to new parent Visual."
This made it happen when you choose Hierarchy 3.

Images are also attached for easy understanding.

I will be glad for your help.
thank you.

I use WPF RadRichTextBox to show/edit HTML-document containing images having restricted access. To show HTML-document inside RadRichTextBox I use HtmlFormatProvider.
In the case of using WebBrowser control, it is enough to call InternetSetCookie to pass user token to the WebRequest used there.

How can I pass the user token to the HTTP request used inside RadRichTextBox to get an image?

Hi,

I have a RadCartesianChart with a ScatterSeriesDescriptor.

Example:

 Public Class PointViewModel

 Public Property MyValueInX As ValueContainer

 Public Property MyValueInY As ValueContainer

End Class

Public Class ValueContainer

 Public Property ValueForDiagram As Double

End Class

When I try to bind ValueForDiagram I get a System.ArgumentException: "Could not find property 'MyValueInX .ValueForDiagram ' for type 'TelerikTestProjekt.ViewModel.PointViewModel'".

My XAML:

            <telerik:ScatterSeriesDescriptor ItemsSourcePath="Points" XValuePath="MyValueInX.ValueForDiagram" YValuePath="MyValueInY.ValueForDiagram ">

Is there any way I can set this binding?

Best Regards

Sandra
