一、dataGridView
1.右键出快捷菜单
if (e.Button == MouseButtons.Right)
{
if (e.RowIndex >= 0)
{
//若行已是选中状态就不再进行设置
if (DGVInfo.Rows[e.RowIndex].Selected == false)
{
DGVInfo.ClearSelection();
DGVInfo.Rows[e.RowIndex].Selected = true;
}
//只选中一行时设置活动单元格
if (DGVInfo.SelectedRows.Count == 1)
{
DGVInfo.CurrentCell = DGVInfo.Rows[e.RowIndex].Cells[e.ColumnIndex];
}
//弹出操作菜单
contextMenuStrip2.Show(MousePosition.X, MousePosition.Y);
}
}
2.datagridview怎么操作完之后刷新
DGVInfo.DataSource = dt;
DGVInfo.Refresh();
二、界面
1.messbox
选择是否执行对话框
if (MessageBox.Show("您确定要退出系统吗?", "提示", MessageBoxButtons.YesNo, MessageBoxIcon.Question) == DialogResult.Yes)
{}
2.点击一个按钮执行另一个按钮
btnOffLine_Click(sender,e);
3.清空Text文本
foreach (Control Ctrol in this.Controls)
{
if (Ctrol is TextBox)
{
Ctrol.Text = "";
}
}
4.PasswordChar 为0
txt_Password.PasswordChar = '\0';
5. 控件随窗体变大
this.WindowState = FormWindowState.Maximized;
panel1.Width = this.Width;
```
