C1FlexGrid 右击菜单ContextMenuStrip

1.有单元格右击，不显示菜单。 2.现在窗体加入控件ContextMenuStrip。

 1 private void fgMain_MouseClick(object sender, MouseEventArgs e)
 2     {
 3         if (e.Button == MouseButtons.Right)
 4         {
 5             int row = this.fgMain.MouseRow;
 6             int col = this.fgMain.MouseCol;
 7 
 8             if (row < 1 || col < 1)
 9             {
10                 return;
11             }
12 
13             this.fgMain.Focus();
14             this.fgMain.Select(row, col);
15 
16             if ((row == 1 && col == 1))
17             {
18                 return;
19             }
20 
21             if (this.fgMain.Rows.Count > 30)
22             {
23                 this.fgMain.ContextMenuStrip = this.menuFG;
24                 this.fgMain.ContextMenuStrip.Show(Cursor.Position);
25             }
26         }
27     }
28 
29     private void fgMain_BeforeMouseDown(object sender, BeforeMouseDownEventArgs e)
30     {
31         this.fgMain.ContextMenuStrip = null;
32     }
