DataGridView扩展方法行号、全选
[csharp]
/// <summary>
/// DataGridView添加行号
/// </summary>
/// <param name="dgv">DataGridView控件ID</param>
public static void AddRowIndex(this DataGridView dgv)
{
dgv.RowPostPaint += delegate(object sender, DataGridViewRowPostPaintEventArgs e)
{
SolidBrush b = new SolidBrush(dgv.RowHeadersDefaultCellStyle.ForeColor);
e.Graphics.DrawString((e.RowIndex + 1).ToString(), dgv.DefaultCellStyle.Font, b, e.RowBounds.Location.X + 10, e.RowBounds.Location.Y + 4);
};
}
/// <summary>
/// DataGridView添加全选
/// </summary>
/// <param name="dgv">DataGridView控件ID</param>
/// <param name="columnIndex">全选所在列序号</param>
public static void AddFullSelect(this DataGridView dgv, int columnIndex)
{
if (dgv.Rows.Count < 1)
{
return;
}
CheckBox ckBox = new CheckBox();
Rectangle rect = dgv.GetCellDisplayRectangle(1, -1, true);
ckBox.Size = new Size(dgv.Columns[1].Width - 12, 12); //大小
Point point = new Point(rect.X + 10, rect.Y + 3);//位置
ckBox.Location = point;
ckBox.CheckedChanged += delegate(object sender, EventArgs e)
{
for (int i = 0; i < dgv.Rows.Count; i++)
{
dgv.Rows[i].Cells[columnIndex].Value = ((CheckBox)sender).Checked;
}
dgv.EndEdit();
};
dgv.Controls.Add(ckBox);
}
