Binding Tooltip to template element

Blikkies

Hey guys, I have added a TextBlock in one of my ItemTemplate, How can I bind the element parent's tooltip text to my TextBlock text for example:

I know this is wrong, because the tooltip uses ToolTipService. Thanks

There's nothing wrong with your sample there. That works perfectly well, assuming that MyParent is accessible to SubText.

I've try it but no luck, "MyParent" is a ListBox control, i have created a DataTemplate where SubText TextBlock is in and i've tried to bind the lisbox tooltip to the subtext text but failed Miserably.

Why not just bind the tooltip in MyParent to the same element you are binding to as SubText?

Hi You can create a custom control based on what control you are using as parent. If you are using ListBox it would be like below

public class CustomListBox : ListBox
{
public object ToolTip
{
get
{
return ToolTipService.GetToolTip(this);
}
}
}

You xaml will look like below

<local:CustomListBox ItemsSource="{Binding Path=CustomerList}"
ToolTipService.ToolTip="Your Tooltip"
x:Name="lstParent">
local:CustomListBox.ItemTemplate
<DataTemplate>
<TextBlock Text="{Binding Path=ToolTip, ElementName=lstParent}" />
</DataTemplate>
</local:CustomListBox.ItemTemplate>
</local:CustomListBox>

Let me know if it works. http://www.exploresilverlight.com Cheers! Vinod
