Hi all,
I have just a problem with validation when using the new Q2 2010 (0714)  telerik released dll.
I cannot show full error message when validation with RadCombobox and RadDatePicker( just have a very small red box appeared)
I tested with normal ComboBox (Silverlight Control) and error message when validate is very good. But when I replace by RadComboBox then has this inconvenience.
I guess because telerik inputcontrol.???

Thanks in advance,
Best regards,
balv

Hello i have also a question,
i made some color changes (not in radcombo) in the office_blue theme after that i replaced it in my project.
Now i get this errormessage in outputwindow:

System.Windows.Data Error: Fehler bei Verbindung mit Index '0' in Objekt 'System.Collections.ObjectModel.ReadOnlyObservableCollection`1[System.Windows.Controls.ValidationError]' (Typ 'System.Collections.ObjectModel.ReadOnlyObservableCollection`1[System.Windows.Controls.ValidationError]'). BindingExpression: Path="(Validation.Errors)[0].ErrorContent" DataItem="Telerik.Windows.Controls.RadComboBox" (HashCode=17053313); Zielelement ist "Telerik.Windows.Controls.Chromes.ValidationTooltip" (Name="ValidationTooltip"); Zieleigenschaft ist "TooltipContent" (Typ "System.Object").


I didn't change anything in the radcombo.xaml theme-file. What is the reason for this ValidationError?
We are using latest RadControls_for_Silverlight_4_2010_2_0716 Version.
Greetings ....

Hi,

The missing text in the tooltip should be fixed in the last internal build RadControls_for_Silverlight_4_2010_2_0716_DEV.zip.

If you are using custom theme you may need to update the ValidationTooltip's ValidationTooltip.xaml with the attached one. And the TooltipContent property on the ValidationTooltip (where it is used) should be set to:

TooltipContent="{Binding Path=(Validation.Errors), RelativeSource={RelativeSource TemplatedParent}}"

Kind regards,
