Description

How to increase/decrease the period that a tooltip for a GridViewCell is visible.

Solution

You can change the tooltip duration by setting the ToolTipService.ShowDuration attached property of the cells via a style.

Example 1: Setting ToolTipService.ShowDuration

XAML

    
    <Window.Resources>
	<!-- If you're using the NoXaml binaries, you need to add the BasedOn="{StaticResource GridViewCellStyle}" attribute -->
        <Style TargetType="telerik:GridViewCell">
	    <Setter Property="ToolTipService.ShowDuration" Value="1000" />
	</Style>
    </Window.Resources>

If you do not want to apply this style to all GridViewCells in your application, you can use the CellStyle property of the columns to apply it only to a specific column.
