How do I get the mouse over item, and show tooltip

[Tao Jiang]

Hi,

I am using Treeview to show a recursive data structure. I would like to get the item when mouse is over, process the value of the item and show tooltip.

How can I get the item?

Thanks,

Hi Tao,

Below is a code snippet that demonstrates how to display a tooltip for each treeview item, depending on some information contained in the business object that the treeview item is data bound to:

<telerikNavigation:RadTreeView x:Name="treeView">
    <telerikNavigation:RadTreeView.ItemTemplate>
        <DataTemplate>
            <Grid ToolTipService.ToolTip="{Binding TootipText}">
                <TextBlock Text="{Binding Header}" />
            </Grid>
        </DataTemplate>
    </telerikNavigation:RadTreeView.ItemTemplate>
</telerikNavigation:RadTreeView>

In the sample the tooltip is bound to a text property called TooltipText. In case you need to do some more complex operation to determine the tooltip content, you can create a ValueConverter to do whatever you need to do to get the required tooltip.

Let me know if you have other questions.
