Disable selection rectangle? (Read 4390 times)

	Is there a way to programmatically enable/disable the selection rectangle? I've tried setting my_chart.Selection.AllowMultiSel to false, but that only seems to disallow adding more than one object to the selection. Is there some other API that I'm missing? Thanks for any info, -lipp

	Try setting fc.ModifierKeyActions.Control = ModifierKeyAction.None; That should work as long as Behavior is not set to Modify (Modify lets you draw a selection rectangle without holding Control). Stoyan

	Hmm...doesn't seem to make a difference. Behavior is set to CreateArrow. -lipp

	Ok, it seems CreateArrow lets you draw selection rectangles without holding Ctrl too. Try handling the MouseMove event and check whether there is a node under the mouse pointer - if there is a node, set Behavior to CreateArrow; if there isn't, set Behavior to DoNothing. Stoyan

	I haven't given this a try yet, but I was just thinking: I don't want to switch Behavior back to DoNothing if I'm in the process of creating an arrow, right? Is there a way to tell from my MouseMove handler whether the chart control is currently creating an arrow? Thanks again, -lipp

	You are right - check the MouseEventArgs.Button property before changing the Behavior to DoNothing. Change it only if e.Button == MouseButtons.None. Stoyan

	That works great! Thanks, -lipp ps: For what it's worth, it would be nice if this level of control over the selection rectangle was some provided by the FlowChart directly. Thanks again for your help.

	You need to allow single-item selection by clicking items but not by drawing a selection rectangle ? Stoyan

	As it happens, I'm trying to disable all selection (single & multiple) while still allow creation of arrows. But, it would be nice to be able to enable/disable single selection & multiple selection independently. In particular, I assumed that setting Selection.AllowMultiSel to false would disable the selection rectangle, regardless of behavior.
