Node Events
EDIDocumentViewer a exposes an event called NodeSelected. This will allow developers to know when a node is selected. A node can be either a loop, segment, element or composite element.
Example
ediDocumentViewer1.NodeSelected += new System.EventHandler<RDPCrystalEDILibrary.UI.Winforms.EDINodeSelectedEventArgs>(NodeSelected);
private void NodeSelected(object sender, EDINodeSelectedEventArgs e)
{
if (e.SelectedObject is DataElement)
{
}
else if (e.SelectedObject is LightWeightElement)
{
}
else if (e.SelectedObject is Loop)
{
}
else if (e.SelectedObject is LightWeightLoop)
{
}
}
Depending on if you were displaying an EDIDocument or a EDILightWeightDocument the SelectedObject will be of that category type.
