Gridview header disappears when mouse is hovered over the header

[Alex]

Hi,

 

I am trying to make a universal style which would show header tooltip for every column in a gridview. In generic.xml I defined this style:

<Style TargetType="telerik:GridViewHeaderCell">
     <Setter Property="ToolTip" Value="{Binding RelativeSource={RelativeSource Self}, Path=Content}" />
</Style>

This does show the tooltip, however when mouse pointer is hovered over the column header then the actual column header gets cleared. The tooltip stays. I tried to set binding mode to TwoWay but it doesn't change this behavior. How can this be fixed if I'd like to keep styling global?

Hi Telerik Team,

could you please reply? Even if my question is invalid in any way, could you please let me know?

With lack of answer, I updated my XAML with new data definition as explained in your documentation:

<telerik:GridViewDataColumn DataMemberBinding="{Binding Name}"><telerik:GridViewDataColumn.Header><TextBlock Text="Name" ToolTipService.ToolTip="My very long header"/></telerik:GridViewDataColumn.Header></telerik:GridViewDataColumn>

https://docs.telerik.com/devtools/wpf/controls/radgridview/how-to/create-tooltip

 

This created two problems straight away: styling of grid headers broke (try to hover over) and also excel export fails to pick up new updated header. To avoid unwanted coding, I would still prefer to fix the binding if this is possible. Could you please advise?

I sorted it out by adding a converter
