Demos - Telerik UI for WPF

Just installed the latest WPF controls and the Demo app but the demo app isn't working. The app is looking for Telerik.Windows.Control version 2015.3.930.40 and failing to find that version, but I have 2015.3.930.45 installed locally. Should this be working correctly or is something broken? Thanks.

How can I bind to a property on the PropertyGridFieldStyle?

Hi! I know how to set a custom style for the field of a property grid but I cant figure out how I am supposed to make that style bound to anything that is relative to the specific PropertyDefinition of that field.

The PropertyGridField's PropertyDefinition is the default source the style's binding. The binding path of the PropertyDefinition might be "Communication.Timeout" but I want to bind the FontWeight property to "Communication.TimeoutProperty.Mode". How can this be done?

Do I have to create a subclass of PropertyDefinition with my own dependency properties on to be able to do this?

<telerik:RadPropertyGrid

Name="PropertyGrid"

IsGrouped="True"

Item="{Binding SelectedItem}"

EditMode="Single"

RenderMode="Flat"

FieldStyle="{DynamicResource PropertyGridFieldStyle}"

AutoGeneratePropertyDefinitions="False">

<telerik:RadPropertyGrid.Resources>

<Style x:Key="PropertyGridFieldStyle"

TargetType="{x:Type telerik:PropertyGridField}"

BasedOn="{StaticResource PropertyGridFieldStyle}">

<Setter Property="FontWeight" Value="{Binding Path=???}"/>

</Style>

</telerik:RadPropertyGrid.Resources>

</telerik:RadPropertyGrid>

How to set background color of a single cell?

Hello team,

I want to set the background color of a single cell in my gridview.
The bound object contains a string with the hex value of the color. The property is BackcolorHex.

<telerik:RadGridView Grid.Row="11" Grid.Column="1" Grid.ColumnSpan="4"

AutoGenerateColumns="False"

ItemsSource="{Binding WorkflowView}"

RowHeight="25"

CanUserFreezeColumns="False"

telerikQuickStart:ThemeAwareBackgroundBehavior.IsEnabled="True"

IsSynchronizedWithCurrentItem="True"

IsEnabled="{Binding ModelController.WorkflowHelper.IsWorkflowEditing,

Converter={StaticResource InvertBoolConv}}">

<telerik:RadGridView.Resources>

<Style x:Key="CellBGStyle" TargetType="telerik:GridViewCell">

<Setter Property="Background"

Value="{Binding Path=BackcolorHex,

Converter={StaticResource HexToColorConv}}">

</Setter>

</Style>

</telerik:RadGridView.Resources>

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn Header="Farbe"

CellStyle="{StaticResource CellBGStyle}"

DataMemberBinding="{Binding Path=BackcolorHex,

Converter={StaticResource HexToColorConv}}"

IsReadOnly="True"/>

</telerik:RadGridView.Columns>

</telerik:RadGridView>

This is my converter function:

public object Convert(object value, Type targetType, object parameter,

CultureInfo culture)

{

Brush retVal = new SolidColorBrush(Colors.White);

if (value != null && value is ModelWorkflow)

{

myConverter conv = new myConverter();

retVal = conv.ToBrush(((ModelWorkflow)value).BackcolorHex);

}

return retVal;

}

The string is shown in the cell right. But the backcolor does not change. It's always white. Could you please tell me what i'm doing wrong?

Thank you very much.

Best regards from Germany!

How to move Telerik DLLs?

Hi,

I have a project using various Telerik controls. The wizard set up my project so that the binaries are in the project tree like this:

<MyProjectPath>\lib\RCWPF\2015.1.401.45\

I want to move this whole "2015.1.401.45" directory somewhere and point my references there. That would allow me to have multiple projects reference the binaries without the need to have 83 MB of extra binaries in each project.

If I move the files and re-point the references, I can no longer use the RadGridView. Visual Studio 2013 just can't find it.

Can I move the Telerik binaries and point references to the new location? Are there any tricks involved in the process?

Thanks.

TreeCellContainer image for tasks without children

Hi

This is probably a simple thing to achieve but I'm struggling to come up with the solution!

For tasks without children there is currently no expand/collapse image displayed in the tree cell as you would expect. However, for tasks without children at level 1 would it be possible to display an image - for example a simple bullet-point style image?

Many thanks

Adrian

RadGridView filter displays date in wrong format

I have the problem, that the filter in the Telerik RadGridView has a wrong formatting for date fields. In the grid it self they are drawn correctly. I use the format: dd.mm.yyyy

Please take a look at the attached screenshot.

I set the column culture like this:

GridViewBoundColumnBase column = new GridViewDataColumn();

column.Language = System.Windows.Markup.XmlLanguage.GetLanguage("de-DE");

this.IsLocalizationLanguageRespected = true; // this is the instance of the RadGridView

Thank you!
