Hi,
I have following style applied for all my RadMultiColumnComboBox controls (in the app.xaml):
<!--Telerik default DefaultTelerikRadMultiColumnComboBoxStyle-->
<
Style
x:Key
=
"DefaultTelerikRadMultiColumnComboBoxStyle"
TargetType
=
"telerik:RadMultiColumnComboBox"
BasedOn
=
"{StaticResource RadMultiColumnComboBoxStyle}"
>
<!--<Setter Property="SelectionMode" Value="Single"/>-->
<
Setter
Property
=
"AutoCompleteMode"
Value
=
"Search"
/>
<
Setter
Property
=
"FontFamily"
Value
=
"{StaticResource DefaultFont}"
/>
<
Setter
Property
=
"FontSize"
Value
=
"{StaticResource DefaultFontSize}"
/>
<
Setter
Property
=
"FontWeight"
Value
=
"{StaticResource DefaultFontWeight}"
/>
<
Setter
Property
=
"MinHeight"
Value
=
"{StaticResource DefaultMinimumHeight}"
/>
<
Setter
Property
=
"KeepDropDownOpen"
Value
=
"False"
/>
<
Setter
Property
=
"CloseDropDownAfterSelectionInput"
Value
=
"True"
/>
<
Setter
Property
=
"SelectionBoxesVisibility"
Value
=
"Visible"
/>
<
Setter
Property
=
"Validation.ErrorTemplate"
Value
=
"{StaticResource ErrorTemplate}"
/>
<
Style.Triggers
>
<
Trigger
Property
=
"IsEnabled"
Value
=
"True"
>
<
Setter
Property
=
"Background"
Value
=
"{StaticResource DefaultTextBoxBackgroundColor}"
/>
</
Trigger
>
<
Trigger
Property
=
"IsEnabled"
Value
=
"False"
>
<
Setter
Property
=
"Background"
Value
=
"Red"
/>
</
Trigger
>
<
Trigger
Property
=
"IsFocused"
Value
=
"True"
>
<
Setter
Property
=
"Background"
Value
=
"{StaticResource DefaultTextBoxIsFocusedBackgroundColor}"
/>
</
Trigger

</
Style.Triggers

</
Style

<
Style
TargetType

"{x:Type telerik:RadMultiColumnComboBox}"
BasedOn
=
"{StaticResource DefaultTelerikRadMultiColumnComboBoxStyle}"
/>
With this style applied, I get this error in my XAML files (see attached file): The element "[RadMultiColumnComboBox]" could not be displayed because of a problem with System.Windows.StaticResourceExtension: CollectionView must have value. Parameter name: collectionView.
The error is provoced by the setter of the AutoCompleteMode. The error disappears when this setter is deleted.
Setting the AutoCompleteMode directly on a RadMultiColumnComboBox (with the style applied) does not cause any problems.
Any ideas ??

Hans
