What is the proper way to use a template selector for RadGridView? Templates are currently not being selected and my SelectTemplate method in DetailsTemplateSelector is not being called. I'm using this currently:

<telerik:RadGridView.RowDetailsTemplate>
<DataTemplate>
<ItemsControl
ItemTemplateSelector="{StaticResource detailsTemplateSelector}"
/>
</DataTemplate>
</telerik:RadGridView.RowDetailsTemplate>

Resources:

<Window.Resources>
<DataTemplate x:Key="theBasicView">
<controls:InfoDetailsControl InfoDetail="{Binding InfoDetails}" />
</DataTemplate>

<DataTemplate x:Key="theTableView">
<telerik:RadGridView ItemsSource="{Binding DetailsTable}"
ShowGroupPanel="False"
AutoGenerateColumns="True"
ColumnBackground="Beige"
RowIndicatorVisibility="Hidden"
AlternationCount="2"
/>
</DataTemplate>

<analysis:DetailsTemplateSelector
BasicView="{StaticResource theBasicView}"
TableView="{StaticResource theTableView}"
x:Key="detailsTemplateSelector"
/>
</Window.Resources>

Code behind:

public class DetailsTemplateSelector : DataTemplateSelector
{
public DataTemplate BasicView { get; set; }
public DataTemplate TableView { get; set; }

public override DataTemplate SelectTemplate(object item, DependencyObject container) {
FrameworkElement element = container as FrameworkElement;
if (element != null && item != null && item is ViewableRuleResult)
{
ViewableRuleResult ruleResult = item as ViewableRuleResult;
Window window = Application.Current.MainWindow;

if (ruleResult.DetailsTable == null)
{
return BasicView;
}
else
{
return TableView;
}
}
return null;
}
}

RadExpander VS Theme

Hi,

acually in my application, we use the OfficeBlue theme. In our application we have many RadExpanders and with this theme, all RadExpanders are all white. I want to know how I can change the style of the RadExpander to reflect the style of the RadButton (gradient, etc...)

Thank's

Distinct Values on ComboBoxColumn bug?

I'm trying to make built-in filtering work with a comboboxcolumn.

My GridView is bound to an ObservableCollection of Racer entities.

Each Racer entity has a BikeID property (of type Guid) and a Bike navigation property (of type Bike).

My ViewModel has a class BikeService which has an Items Collection of ComboItemViewModel,

which in turn has "ID" and "Description" public properties.

The following code seems to be working, except for the distinct values part of the filtering control.

Basically, I get an exception for each distinct value because the filtering control is trying to parse

them as Guid, even if I instructed the GridView to filter on Bike.Description, which is a string.



Exception text:

System.Windows.Data Error: 17 : Cannot get 'ConvertedValue' value (type 'Object') from '' 

(type 'DistinctValueViewModel'). BindingExpression:Path=ConvertedValue; DataItem='DistinctValueViewModel'

(HashCode=52842714); target element is 'CheckBox' (Name=''); target property is 'Content' (type 'Object')

TargetInvocationException:'System.Reflection.TargetInvocationException: 

Eccezione generata dalla destinazione di una chiamata. ---> 

System.FormatException: Il GUID deve contenere 32 cifre, separate da quattro trattini (xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx).



<

telerik:GridViewComboBoxColumn

Header="Bike"

DataMemberBinding="{Binding BikeID}"

SortMemberPath="Bike.Description"

FilterMemberPath=

"Bike.Description"

                      FilterMemberType="{x:Type sys:String}"

ItemsSource=

"{Binding RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type UserControl}}, Path=DataContext.BikeService.Items}"

SelectedValueMemberPath="ID"

DisplayMemberPath="Description"

/>



I suspect this is a bug, or maybe this is not supported by the current version of GridView.



Thanks in advance,

Dynamic columns + static column

I am trying to build a grid that has both a static, known column and a set of unknown columns that need to be created dynamically. I have read and understand the method of using DynamicObject combined with the auto generate columns from the RadGridView, but in my situation I want the one known column (the "non-dynamic" one) to be editable, and the dynamic columns readonly (non editable).

Please advise...

Thanks!
