[Solved] Enumerator gives error in XAML

[Jonam]

http://www.telerik.com/help/silverlight/radcombobox-howto-bind-enum-values.html

i used the methode above to databind an enumerator to a combobox. The method works perfect only in the designer i get an error that the enumerator type is unkown.

<

 

 

model:EnumViewModel x:Name="KavelVerdelingSource" EnumType="System.Windows.Controls.ClickMode"/>

Error 26 Type 'System.Windows.Controls.ClickMode' was not found. C:\Projects\Klanten\Rekenenteken - kopie\Brink Interface\Main\Controls\DataControls\BestaandKavelDataControl.xaml 18 9 Brink Interface

any suggestions?

Hi Jonam,

The reason for this error is that the typeconverter is not executed at designtime. You can fix it by changing the type of EnumType property to string and convert it later in EnumViewModel class. I've attached an example, please download it and examine it.

Best wishes,

Hello Yana,

thank you. The solutions worked perfect for me!

kind regards,

Jonam

[Jonam]

Sorry works perfect except when you have a datatemplate somewhere in the control. If you have a datatemplate somwhere you get an Invalid XAML exception?

Hello Jonam,

Could you please send us sample code as we're not able to reproduce the described issue? Thanks

All the best,

<telerik:RadComboBox Margin="3" Height="26" Grid.Column="1" Grid.Row="3"

                                                    SelectedItem="{Binding VerdeelAlgoritme, Mode=TwoWay}"

                                                    ItemsSource="{Binding Source={StaticResource KavelVerdelingSource}, Path=Values}"/>

the above sample is the total code. If i remove this part then everything works fine. Any ideas?

Hi Jonam,

I'm afraid that we're still not able to reproduce the issue. Could you please open a support ticket and attach a runnable project demonstrating the problem there. Thanks in advance

Best wishes,
