Examples

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.
private:
    void InitialTreeView_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.");
        }
    }

// 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.");
    }
}

' 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
