如何以编程方式将ListBox.Tooltip绑定到DataTable？

Question

How to bind ListBox's * ToolTip * to DataTable?

There is only ListBox.ItemsSource , but there is not ListBox.ToolTip.ItemsSource .

Answer 1

ToolTip is a ContentControl , not a ItemsControl . That means that it could contain only single element and not a collection.

To show multiple items in the ToolTip you need to place some ItemsControl ( ListBox , for example) into the TabControl and then use its ItemsSource property.

ListBox list = new ListBox();
ToolTip tooltip = new ToolTip();
ListBox tooltipList = new ListBox();

list.ToolTip = tooltip;
tooltip.Content = tooltipList;
tooltipList.ItemsSource = /*your source*/

Answer 2

You might want to try the following:

WPF Show data from multiple DataContexts in ToolTip of ItemsControl

The link above contains a more advanced scenario, however it could be used to extract the code required for your implementation.
