如何让菜单弹出在鼠标所点位置
在dataGridView中点右键弹出菜单,菜单位置怎么控制?
我的dataGridView的选中方式为:FullRowsSelect
程序为:
private void dataGridView_CellMouseDown(object sender,DataGridViewCellMouseEventArgs e)
{
if(e.button==MouseButton.Right && e.ColumnIndex > -1 && e.RowIndex > -1)
{
dataGridView.Rows[e.RowIndex].Cells[e.ColumnIndex].Select=true;
ContextMenu con = new ContextMenu ();
MenuItem Add_user = new MenuItem Add_user ("添加");
MenuItem menuLine1_user= new MenuItem ("_");
MenuItem Update_user = new MenuItem Add_user ("修改");
MenuItem menuLine2_user= new MenuItem ("_");
MenuItem Delete_user = new MenuItem Add_user ("删除");
Add_user.Click += new EventHandler(this.Add_user_click_ToolStripMenuItem_Click);
Update_user.Click += new EventHandler(this.Update_user_click_ToolStripMenuItem_Click);
Delete_user.Click += new EventHandler(this.Delete_user_click_ToolStripMenuItem_Click);
con.MenuItems.Add(Add_user);
con.MenuItems.Add(menuLine1_user);
con.MenuItems.Add(Update_user);
con.MenuItems.Add(menuLine2_user);
con.MenuItems.Add(Delete_user);
this.dataGridView.ContextMenu = con;
con.Show(dataGridView,new point(e.X,e.Y));//就是这句,菜单都是乱蹦的!怎么控制啊?
}
}

C# code
private void dgvList_CellMouseDown(object sender, DataGridViewCellMouseEventArgs e)
{
if (e.Button == MouseButtons.Right)
{
if (e.RowIndex >= 0)
{
if (dgvList.Rows[e.RowIndex].Selected == false)
{
dgvList.ClearSelection();
dgvList.Rows[e.RowIndex].Selected = true;
}
if (dgvList.SelectedRows.Count == 1 && e.ColumnIndex != -1)
{
dgvList.CurrentCell = dgvList.Rows[e.RowIndex].Cells[e.ColumnIndex];
}
dgvList.ContextMenuStrip = contextMenuStrip1;
}
else
{
dgvList.ContextMenuStrip = null;
return;
}
}
}
