Hello Maya,

I'm facing the same problem at the moment and your link lead me only half the way to a solution. Implementing codeplex's ToolTipService gives access to the fields needed. The main problem is where to set the tooltip. I'm using GridViewDataColumns and the only property available is ToolTipTemplate which points to the ContentTemplate of a fixed ToolTip. How can I change the default ToolTip of those columns?

As soon as this information is provided it should be really easy to set the ToolTip to the custom one and get tooltips that last longer/shorter than the default ones.

Kind regards,
Hans-Peter

Hi Hans,

You may define this ToolTip on a column as follows:

xmlns:Controls="clr-namespace:Silverlight.Controls.ToolTips;assembly=Silverlight.Controls.ToolTips"

<telerik:GridViewDataColumn DataMemberBinding="{Binding Name}">
                    <telerik:GridViewDataColumn.CellTemplate>
                        <DataTemplate>
                            <TextBlock Text="{Binding Name}"  >
                                <Controls:ToolTipService.ToolTip>
                                    <Controls:ToolTip Content="{Binding Name}" DisplayTime="00:00:01" />
                                </Controls:ToolTipService.ToolTip>
                            </TextBlock>
                        </DataTemplate>
                    </telerik:GridViewDataColumn.CellTemplate>
                </telerik:GridViewDataColumn>

Another possible approach is to handle the RowLoaded event:

void playersGrid_RowLoaded(object sender, RowLoadedEventArgs e)
        {
            var row = e.Row as GridViewRow;
            var cells = row.ChildrenOfType<GridViewCell>();
            foreach (GridViewCell cell in cells)
            {
                var tooltip = new Silverlight.Controls.ToolTips.ToolTip();
                tooltip.DisplayTime = new Duration(new TimeSpan(0,0,3));
                tooltip.Content = (cell.Column as GridViewDataColumn).DataMemberBinding.Path.Path;
                cell.SetValue(Silverlight.Controls.ToolTips.ToolTipService.ToolTipProperty, tooltip);

            }
        }
