Diagram link margin where the link fired the mouse over / click events (Read 5571 times)

	Hi, In the WinForms version, we had a margin around the link where it fired the events. In the WPF version user have to click exactly on that 1-pixel wide link. Is it possible to return back this behavior? Thanks, -Kostya

	Hi, That depends on the Diagram.LinkHitDistance property; check if you haven't set it to a small value. I hope that helps, Stoyan

	Thanks Stoyan, one clarification then: I actually need to open the popup menu on the link but not to aim at the 1px line. So the LinkHitDistance helps to select a link by clicking. But the problem is that I would like to open the link context menu, with right mouse button, so that the line isn't selected in this way. -Kostya

	LinkHitDistance is also considered when raising LinkClicked event, so you could show the context menu from LinkClicked handler: Code private void OnLinkClicked(object sender, LinkEventArgs e) { if (e.MouseButton == MouseButton.Right) { var contextMenu = new ContextMenu(); ... contextMenu.Placement = System.Windows.Controls.Primitives.PlacementMode.Mouse; contextMenu.IsOpen = true; } } If you use WPF's FrameworkElement.ContextMenu property, it will show only when you click pixels rendered by the link indeed. In such case try showing it from LinkClicked handler too: Code ... e.Link.ContextMenu.IsOpen = true; ... I hope that helps, Stoyan

	Stoyan, thank you, it works! Can I expect to see the Diagram.LinkHitDistance property as a DependencProperty, to use in styles?

	Stoyan, sorry: all the same, can you please let me know about the possibility of adding this as a DependencProperty?

	It's a dependency property in this build: https://mindfusion.eu/_beta/wpfdiag321.zip I hope that helps, Stoyan
