- Windows form
- ListView Control
- ContextMenu Strip
Step-1:Loading listview items::
The following code loads the items to listview control.
protected void load_courses()
{
//code for loading the courses
try {
OleDbConnection conn = new OleDbConnection(StaticData.connection_string);
conn.Open();
string select_courses = "select * from Course";
OleDbDataAdapter oda = new OleDbDataAdapter(select_courses, conn);
DataTable dt = new DataTable();
oda.Fill(dt);
//databinding to the listview
TestlistView.Items.Clear();
for(int i=0;i < dt.Rows.Count;i++)
{
DataRow row = dt.Rows[i];
ListViewItem lvi = new ListViewItem(row["CourseNo"].ToString());
lvi.SubItems.Add(row["CourseID"].ToString());
lvi.SubItems.Add(row["Credit"].ToString());
TestlistView.Items.Add(lvi);
}
}
catch (Exception exc) { }
}
private void Form1_Load(object sender, EventArgs e)
{
//code for loading the courses
load_courses();
}
Step-2:Handling the right click event on listview items:
private void TestlistView_MouseClick(object sender, MouseEventArgs e)
{
if (e.Button == MouseButtons.Right)
{
Point pt = TestlistView.PointToScreen(e.Location);
contextMenuStrip1.Show(pt);
}
}
Step-3:Handling context menu strip event
private void contextMenuStrip1_ItemClicked(object sender, ToolStripItemClickedEventArgs e)
{
if (e.ClickedItem.Text == "Upload")
{
MessageBox.Show("Upload started for:" + TestlistView.SelectedItems[0].Text);
}
}
Thats how we can use right click event to show a context menu strip and handle menu strip click events.
