	1) This is not supported. 2) Try calling diagram.Interaction.CancelNow() in response to the ESC key-down event. Stoyan

	Thanks Stoyan, I have tried diagram.Interaction.CancelNow(), it is working fine except one little issue. When I select any node and drag it, at this time if I press Escape, nothing happens. Escape works when I move the mouse 1 pixel. If I don�t move the mouse, interaction state doesn�t cancel the drag. I want if I press Escape; node should immediately cancel the drag operation without waiting for mouse to move. Please give your suggestion on this. Regards, Anshul

	Hi Anshul, Try the Diagram.CancelDrag method from this version: https://www.mindfusion.eu/_beta/wpfdiag_canceldrag.zip I hope that helps, Stoyan

	Hi Stoyan, When you are going to release next licensed build of Mindfusion.Diagramming.Wpf. Will that build include this CancelDrag() method ? Regards, Anshul

	Hi Stoyan, I am using ModificationEffect Property to view the clone movement effect; this is working fine for me except in one case. If I select any node in the diagram and than try to move some another node, in this time clone effect not works. I need to select that node than only I can move that node but if not anyone node is selected in the diagram than everything works fine. Please suggest if anyone node is selected and I want to move another node, how can I get ModificationEffect in that? Regards, Anshul

	Hi Anshul, Are you using ModificationStart="AutoHandles" to move nodes without selecting them? This worked fine in my test. Stoyan

	You can assign MoveShades to ModificationEffect; and there is a different property called ModificationStart. I was wondering if you are using the latter to allow moving nodes that are not selected, or are doing that by some other means.

	Hi Stoyan, I am using version 2.2.1, it does not have ModificationStyle property. Is it a new one? Sorry by mistake I have written ModificationStart instead of ModificationEffect. With your suggestion I have tried this. Now it is working fine but has a small issue. When I move mouse over the node it appears selected. 1). Can I remove this behavior (item appear as selected while mouse over? 2). If not; on mouse leave from that node, node appears selected till some distance. Can I handle this distance or can minimize it? Regards, Anshul

	Hi Anshul, Yes, it's ModificationEffect. You could change the HandlesStyle of items dynamically in response to the NodeSelected and Deselected events. For deselected nodes set InvisibleMove, and for selected nodes set SquareHandles (if that's what you were using originally). I hope that helps, Stoyan

	Hi Stoyan, I have tried NodeSelected and NodeDeselected events. These events called when we select or deselect the node so in our case it is of no use. What happening here is that when mouse enters to the node, DrawAdjustmentHandles event of the diagram gets called and it draws a selection rectangle around the nodes (node is not getting select but appear as selected due to selection handle ) but when mouse leave from that node, node appear selected for few distance say 20 pixels and after that selection handle goes away. I don�t want this selection handle while mouse enter to the node. Now please suggest how to remove this selection handle. Regards, Anshul

	Quote: node is not getting select but appear as selected due to selection handle This happens when ModificationStart = AutoHandles, which you set in order to allow dragging a node without selecting it first. The adjustment handles appear automatically in order to let you grab one and start modifying the node. If you don't want the handles seen with AutoHandles but still need to move unselected nodes, you can use the InvisibleMove HandleStyle and toggle between it and the style you are currently using. You can change the HandlesStyle value in response to the node selection events, or the global SelectionChanged event. If you custom-draw the handles anyway, you could move the drawing code to an "if (e.Node.Selected)" block, so they don't appear when the mouse hovers over the node. You won't have to toggle between the different handles styles in such case. I hope that helps, Stoyan

	Hi Stoyan, We are using ModificationStart = AutoHandles. But it is not allowing us to create link between two nodes when we select DrawLink Mode. Instead of that it makes the node to move. We want both behaviour, when we select DrawLink I should be able to Draw the links , otherwise when I select AutoHandle , the normal behaviour . Regards, Anshul

	Hi Anshul, Change the HandlesStyle to a value different from InvisibleMove when setting up your DrawLink mode, or set ModificationStart back to SelectedOnly. I hope that helps, Stoyan
