Tooltip disappear very quickly ( few ms) after be rendered

[Christophe]

Hello,

I currently encounter a weird issue with Tooltip in Datagrid. All is working fine on my PC for the development.

Unfortunately on my collegue's laptop the tooltip disappear very quickly. 

I tried to style the tooltip with no success

<Style x:Name="ToolTipStyle" TargetType="ToolTip">

                <Setter Property="ToolTipService.InitialShowDelay" Value="100"/>

                <Setter Property="ToolTipService.HasDropShadow" Value="False"/>

                <Setter Property="ToolTipService.IsEnabled" Value="True"/>

                <Setter Property="ToolTipService.Placement" Value="Left"/>

                <Setter Property="ToolTipService.BetweenShowDelay" Value="2000"/>

                <Setter Property="ToolTipService.ShowDuration" Value="5000"/>

            </Style>

Hi Christophe,

The reported issue is a known one. It  occurs while using with VS2022 Preview with .Net 6.0 and Scaling 150. We could reproduce the issue in simple sample with Button and ToolTip and raised query in GitHub. Please find the below link, 

GitHub link: https://github.com/dotnet/wpf/issues/6283

We will update you further details, once we get a proper solution from GitHub.

We appreciate your patience until then.

Thank you for your feedback. Any workaround ? 

It's not a big deal for now.

Hi Christophe,

We have used the default ToolTipService to display the tooltip in SfDataGrid. We regret to inform you that there is no workaround provided from MSDN.
However, you can temporarily avoid this problem by reduce the scaling from 150 to 100 in issue reproduced system or use the .Net 5.0.

As we mentioned earlier, we will update you further details, once we get a proper solution from GitHub. 

 

We appreciate your patience until then.
