1) 行右键菜单

private void dataGridView1_CellMouseDown(object sender, DataGridViewCellMouseEventArgs e)

{

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 (dataGridView1.Rows[e.RowIndex].Selected == false)

{

dataGridView1.ClearSelection();

dataGridView1.Rows[e.RowIndex].Selected = true;

}

//只选中一行时设置活动单元格

if (dataGridView1.SelectedRows.Count == 1){

dataGridView1.CurrentCell = dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex];

}

if (dataGridView1.CurrentRow != null)

{

int idx = dataGridView1.CurrentRow.Index;

if (idx >= 0)

{

string isexport = mDataTableCun.Rows[idx]["ISEXPORT"].ToString();

if (isexport == "已导出")

{

//弹出操作菜单

contextMenuStrip1.Show(MousePosition.X, MousePosition.Y);

}

}

}

}

}

}

2) 行自动编号

private void dataGridView1_RowPostPaint(object sender, DataGridViewRowPostPaintEventArgs e)

{

Rectangle rectangle = new Rectangle(e.RowBounds.Location.X,

e.RowBounds.Location.Y,

dataGridView1.RowHeadersWidth - 4,

e.RowBounds.Height);

TextRenderer.DrawText(e.Graphics, (e.RowIndex + 1).ToString(),

dataGridView1.RowHeadersDefaultCellStyle.Font,

rectangle,

dataGridView1.RowHeadersDefaultCellStyle.ForeColor,

TextFormatFlags.VerticalCenter | TextFormatFlags.Right);

}

3) 单元格取值设值

private void dataGridView1_CellContentClick(object sender, DataGridViewCellEventArgs e)

{

if (e.ColumnIndex == 2)

{

dataGridView1.EndEdit();

string ischeck = dataGridView1.Rows[e.RowIndex].Cells["visible"].Value.ToString();

if (ischeck == "0")

{

dataGridView1.Rows[e.RowIndex].Cells["edit"].Value = "0";

}

}

}
