C#：    private void TestContextMenu_Load(object sender, EventArgs e)    {        DataTable matTable = new DataTable();        matTable.Columns.Add("MAT_IMG", typeof(string));        matTable.Columns.Add("MAT_DESC1", typeof(string));        matTable.Rows.Add();        matTable.Rows[0]["MAT_IMG"] = "log";        matTable.Rows[0]["MAT_DESC1"] = "COMS";        matTable.Rows.Add();        matTable.Rows[1]["MAT_IMG"] = "logon";        matTable.Rows[1]["MAT_DESC1"] = "smobiler";        this.gridView1.DataSource = matTable;        this.gridView1.DataBind();    }

B. CellLongClick Event code

VB：   Private Sub gridView1_CellLongClick(sender As Object, e As GridViewCellEventArgs) Handles gridView1.CellLongClick       contextMenu1.Show()   End Sub
