C# winform DatagridView 的簡單操作

數據顯示操作：

dgBill.Columns[0].DataPropertyName = "key1";
dgBill.Columns[1].DataPropertyName = "key2";
dgBill.Columns[2].DataPropertyName = "key3";

DataTable dt = new DataTable();
dt.Columns.Add("key1", Type.GetType("System.String"));
dt.Columns.Add("key2", Type.GetType("System.String"));
dt.Columns.Add("key3", Type.GetType("System.String"));

DataRow dr = null;

dr = dt.NewRow();

dr["key1"] = "key1";
dr["key1"] =  "key2";
dr["key1"] = "key3";
dt.Rows.Add(dr);
this.dgBill.DataSource = dt;

選擇一行數據：

//右鍵菜單事項
private void dg1_CellMouseDown(object sender, DataGridViewCellMouseEventArgs e)
{
if (e.Button == MouseButtons.Right)
{
if (e.RowIndex >= 0)
{
//若行已是選中狀態就不再進行設置
dg1.ClearSelection();
dg1.Rows[e.RowIndex].Selected = true;

//設置當前行
dg1.CurrentCell = dg1.Rows[e.RowIndex].Cells[0];

//彈出操作菜單
contextMenuStrip1.Show(MousePosition.X, MousePosition.Y);
}
}
}

//選擇菜單的時候，進行獲取右鍵一行的數據

DataGridViewRow rowData = dgBill.CurrentRow;
if (rowData != null)
{
if (rowData.Cells["ID"].Value != null)
{

}
else
{
MessageBox.Show("數據轉換異常", "提示", MessageBoxButtons.OK);
}
}
