this code working with Degault Style and i get ToolTip on headerColumn Image of XamGriD.

But If i apply style for Grid either at desinTime or Runtime the Tooltip is not seen

Please Reply...

Hi, 

The more information you can provide upfront the better. And if you have a sample that you can send, we can generally get to the bottom of a problem a lot quicker. 

I still need more information from you. Like what are you setting a style on. What style are you setting? What are you doing in the style etc...

Really if you could attach a sample that would be best. 

Thanks,

Hi,

I am sending you the style.

Everything is working fine but when i apply this style tooltip is not seen on header.

Thanks for the style. 

The issue is that your ContentPresenter is being hidden by your Resizer/Dragger elements, if you put them under the ContentPresenter the tooltip will show up:

                                <Rectangle x:Name="Resizer" Opacity="0"  Fill="AliceBlue" Width="5" Grid.Column="1" StrokeThickness="10" 

           Cursor="SizeWE" HorizontalAlignment="Right" VerticalAlignment="Stretch"  />

                                <Rectangle x:Name="Dragger" Opacity="0" Stretch="Fill" Fill="AliceBlue" Grid.Column="0" StrokeThickness="10"/>

                                <ContentPresenter  VerticalAlignment="{TemplateBinding VerticalContentAlignment}" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" >

                                </ContentPresenter>

Thank you Steve... Its Work.

But please can u explane me  what was the issue.Because i commented Dragger Rectangle then it was also worked.

I havent worked so much on style,ContentPresenter,ControlTemplate etc. so please explane . . .

I believe it's b/c the mouse is being handled on the Dragger rectangle, which mean the tooltip is not getting notified that the mouse is over the contentPresenter. 

-SteveZ

hi,

Thanks SteveZ

It just shouldn't have anything positioned over it. It doesn't have to be last. 

-SteveZ

So you mean ContentPresenter should be last at the ControlTemplate......
