TreeNodeMouseClickEventArgs Class

Note: This class is new in the .NET Framework version 2.0.

Provides data for the NodeMouseClick and NodeMouseDoubleClick events.

Namespace: System.Windows.Forms
Assembly: System.Windows.Forms (in system.windows.forms.dll)

public class TreeNodeMouseClickEventArgs : MouseEventArgs
public class TreeNodeMouseClickEventArgs extends MouseEventArgs
public class TreeNodeMouseClickEventArgs extends MouseEventArgs

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.
void treeView1_NodeMouseDoubleClick(object sender, TreeNodeMouseClickEventArgs e)
{
    try
    {
        // Look for a file extension.
        if (e.Node.Text.Contains("."))
            System.Diagnostics.Process.Start(@"c:\" + e.Node.Text);
    }
        // If the file is not found, handle the exception and inform the user.
    catch (System.ComponentModel.Win32Exception)
    {
        MessageBox.Show("File not found.");
    }
}
