Validation Tooltip incorrect message and style

[Lance]

Hi,

I have a databound RadComboBox in my Silverlight 4 application.  When there is a data error it correctly has a red border but when you hover on it, the validation tooltip message is just the name of the object the combo is bound to and not the error message (see comboboxvalidationerror.gif for screen print).  I am using 2011_1_328 version of the RadControls.  Below is my xaml definition of the control:

<telerik:RadComboBox Grid.Column="1" Grid.Row="10" x:Name="cboIndustries" IsFilteringEnabled="True" TextSearchMode="StartsWith" Width="250" DisplayMemberPath="IndustryName" HorizontalAlignment="Left" SelectedItem="{Binding Path=IndustryId, Mode=TwoWay, Converter={StaticResource industryConverter}, NotifyOnValidationError=True, ValidatesOnDataErrors=True, ValidatesOnExceptions=True}"  Margin="0,2,0,2" />

I have some Microsoft Silverlight comboxboxes that are working correctly (see correctvalidationstyleandmessage.gif for screen print).  Please can you help me get the correct error message to appear in the RadComboBox validation tooltip and also could you help me so the style of this message is like the error message for the Microsoft Silverlight comboxbox in the screenprint mentioned above?

Thanks

Hi,

I managed to get the red style for the validation tooltip but I still can't get the correct error message to come through.  Come on Telerik, please give me some help on this.

Hi,

Remove the telerik:StyleManager.Theme="{StaticResource Theme}" from the telerikChromes:ValidationTooltip that is placed in the RadComboBox's ControlTempalte. Note that there are 2 ControlsTemplate for RadComboBox so you have to edit them both.

Add an x:Key on the ValidationTooltip's implicit style and move all resources for the ValidationTooltip in the RadComboBox's dictionary. Note that resources with duplicated x:Key should not be added.

After that set the Style on the RadComboBox to be the Style of the ValidationTooltip (use {StaticResource } with the same name you set for x:Key)

In the TooltipContentTemplate adjust the binding so that it displays a proper error. You can alter the binding or add an additional property to the Path.

Also RadComboBox should (but it obviously does not) behave like the microsoft's combobox validation. Can you share with us how do you use validation in your project. It would be really helpful for us to reproduce this issue so we can fix it and provide consistent behavior.
