Multi-select Treeview control v2.0



This is a multi select TreeView Control for the .NET framework. It is possible to select TreeNodes in multiple ways with or without constraints.


The MWTreeView has a few ways of mouse-selecting the TreeNodes by painting anything from a rubberband to very graphical representations. There is even the possibility, using GDI+, to customize the mouse-selection. It is also possible to have TreeNodes of various colors within the same MWTreeView with multi-selection still working. The MWTreeView has a massive amount of configurable settings so that anyone should be able to tailor it to their needs.

Note that when selecting TreeNodes in code the SelectNode (DeselectNode also exists) method should be used. Note that when changing the colors of a TreeNode the ChangeColors method should be used. Do not just change the colors of a TreeNode.

Note that in order to iterate through the selected TreeNodes the following method has to be used (selected TreeNodes are stored in a Hashtable):

foreach(MWTreeNodeWrapper mwtnw in mwtvMWTreeView.SelNodes.Values)
   MessageBox.Show("The " + mwtnw.Node.Text + 
    " TreeNode is selected.");

I don't care too much about the code posted here as long as the credit for it is not taken by someone else, as long as I am mentioned where the code is used and as long as it is not resold as a TreeView or similar component.
I do however have a much updated version of the MWTreeView that is commercial. You can contact me through email if you are interested in that (mik at netatonce fullstop net, where at is "@" and fullstop is "."). The new one is vastly improved compared to the one posted here.
