TreeNodeMouseClickEventArgs Class
Assembly: System.Windows.Forms (in system.windows.forms.dll)
The following code example demonstrates how to handle the NodeMouseDoubleClick event and how to use the TreeNodeMouseClickEventArgs. To run this example, paste the code into a Windows Form that contains a TreeView named treeView1. Populate treeView1 with the names of files located in the c:\ directory of the system the sample is running on, and associate the NodeMouseDoubleClick event of treeView1 with the treeView1_NodeMouseDoubleClick method in this example.
' If a node is double-clicked, open the file indicated by the TreeNode. Sub treeView1_NodeMouseDoubleClick(ByVal sender As Object, _ ByVal e As TreeNodeMouseClickEventArgs) _ Handles treeView1.NodeMouseDoubleClick Try ' Look for a file extension, and open the file. If e.Node.Text.Contains(".") Then System.Diagnostics.Process.Start("c:\" + e.Node.Text) End If ' If the file is not found, handle the exception and inform the user. Catch MessageBox.Show("File not found.") End Try End Sub 'treeView1_NodeMouseDoubleClick
