I have been successful in implementing the onMouseUp event using a tool from the add-in framework. (See Below)
protected override void OnMouseUp(ESRI.ArcGIS.Desktop.AddIns.Tool.MouseEventArgs arg)
{
}
I want my button that registers the onMouseUp event to be in a Windows form, so I'm trying to accomplish the same thing, but not using the add-in framework. From what I've seen, it looks like I need to use the iTool, iCommand interfaces, but I haven't gotten much farther than that.
Any recommendations/code samples on how to accomplish this task would be appreciated. Thanks.
