DataGridView中添加CheckBox列用于选择行
1,编辑DataGridView,添加一列 CheckBox ,Name 赋值为 "select",如下图:
2,取消 datagridview 的可编辑属性,添加 CellClick 事件,用代码来控制checkbox的选中状态,具体代码如下:
private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)
{
if (e.RowIndex == - || e.ColumnIndex == -) return; if (dataGridView1.Columns[e.ColumnIndex].Name != "select") return; DataGridViewCheckBoxCell cell = (DataGridViewCheckBoxCell)dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex];
if (cell.Value != null && (bool)cell.Value)
{
cell.Value = false;
}
else
{
cell.Value = true;
}
}
3,为datagridview关联一个右键菜单,具体的如何获取datagridview中checkbox选中的行代码如下:
private List<AlarmModel> GetAlarmConfirmModelsByDGVCheckbox()
{
List<AlarmModel> alarmModels = new List<AlarmModel>();
foreach (DataGridViewRow row in dataGridView1.Rows)
{
if (row.Cells["select"].Value != null && (bool)row.Cells["select"].Value)
{
AlarmModel model = row.DataBoundItem as AlarmModel;
if (model == null) continue;
alarmModels.Add(model);
}
}
return alarmModels.Count == ? null : alarmModels;
}
