In order to display ToolTips
when you hover over the invalid cell you can check our Validation
WPF / Silverlight demo. As for the size and styling of the ToolTip
, you can use implicit styles to style it to your liking.
Also, I attached a sample project that demonstrates the approach in the mentioned demo and uses implicit styles to customize the appearance of the ToolTip.
Please examine both examples and let us know if this helps.
