Multi-select Treeview control v2.0

Screenshots

Introduction

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

Details

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.");
}

GeneralDraga and Drop Behavior PinmemberLarry Dodd5-Mar-08 10:45 
I am working with your control which by the way is a great control. What I am trying to do is select multiple treenodes and drag them to another of your treeview controls on the same form. The selection is working just fine. Where the problem comes in is when trying to drag the selection. If I select multiple nodes and drag them straight across with without crossing over any of the nodes in that treeview things are fine. If I cross over any nodes in the treeview that are not selected the selection is gone and a new selection is started. Any help that you can give me on this would be appreciated.
