Hello Venkateswarlu,

I am just checking if you require any further assistance on the matter.

Hi Venkateswarlu,

Thank you for your reply. I have been looking into your requirement and in order to activate the tooltip of the header you could set the ‘ToolTip’ property of the HeaderCellControl style like e.g.:

<Setter Property="ToolTip" Value="{Binding Content, RelativeSource={RelativeSource Self}}"/>

You can find the default styles for the XamGrid components in:

C:\Program Files (x86)\Infragistics\2015.1\WPF\DefaultStyles\XamGrid\generic.xaml

I am attaching a sample application(XamGrid_Header_Tooltip.zip) that shows this approach.

Let me know, if you need any further assistance on this matter.
