The ToolTipService.ToolTip is an attached property. You have to add the assembly like this:
xmlns:ms="clr-namespace:System.Windows.Controls;assembly=System.Windows"
and then in your code use the ToolTipService like this:
<telerikInput:RadComboBox Width="200" ms:ToolTipService.ToolTip="test" >
</telerikInput:RadComboBox>
This should help.

Thanks, it works now.
I did not think of that at first because I had a button with the tooltip service along side the radComBox.
I guest it works for the button because it is part a the System.Windows.Controls namespace too?
Thanks again

I am using RadComboBox and setting Tooltip from code at run time.
By, TooltipService.SetTooltip(radComboBox1, "Hello");
When i execute, RadComboBox doesnt have tooltip.
Instead it throws following exception in output window:
System.Windows.Data Error: Failed to connect to index '0' in object 'System.Collections.ObjectModel.ReadOnlyObservableCollection`1[System.Windows.Controls.ValidationError]' (type 'System.Collections.ObjectModel.ReadOnlyObservableCollection`1[System.Windows.Controls.ValidationError]'). BindingExpression: Path='(Validation.Errors)[0].ErrorContent' DataItem='Telerik.Windows.Controls.RadComboBox' (HashCode=31998529); target element is 'System.Windows.Controls.TextBlock' (Name=''); target property is 'Text' (type 'System.String').
I have tooltip on another control(Hyperlink), which works fine.
is it bug in RadComboBox?
Cheers,

Straight to your question.
Attached you will find a sample running project which contains RadComboBox and a HyperlinkButton each with tooltips. Please try it out and if you still experience problems you can send us a running project which we can test here locally.
If you have further questions please feel free to contact us again.

There should be no problem to bind the tooltip in the xaml like this:
<
telerik:RadComboBox
ToolTipService.ToolTip
=
"{Binding ComboBoxToolTip}"
></
telerik:RadComboBox
>
You can find attached a simple example.

When radCombo is disabled , tooltip service does't work. Any one had this problem ? . do you have any solution for this issue ?
Actually this is expected behavior - the tooltip is not supposed to be shown on disabled controls. The same can be observed with the Silverlight ComboBox as well.
