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 the 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)
