不知道大家有没有这样的经验，当点击或者取消datagridview的checkbox列时，比较难获得其状态是选中还是未选中，进而不好进行其它操作，下面就列出它的解决办法：
主要用到了DataGridView的CurrentCellDirtyStateChanged和CellValueChanged两个事件
CurrentCellDirtyStateChanged事件是提交对checkbox状态的修改
CellValueChanged事件是当状态提交后，也就是单元格值改变后做一些其它的操作
(1). CurrentCellDirtyStateChanged事件代码：
void PositionListDataView_CurrentCellDirtyStateChanged( object sender, EventArgs e)
{
DataGridView grid = sender as DataGridView;
if (grid != null )
{
grid.CommitEdit(DataGridViewDataErrorContexts.Commit);
}
}
(2). CellValueChanged事件代码：
void PositionListDataView_CellValueChanged( object sender, DataGridViewCellEventArgs e)
{
DataGridView grid = sender as DataGridView;
if (grid != null && e.RowIndex >= 0 )
{
if (grid.Columns[e.ColumnIndex].Name == " Check " )
{
DataTable dt = grid.DataSource as DataTable;
int pstnID = Convert.ToInt32(dt.Rows[e.RowIndex][ 1 ]); DataGridViewCheckBoxCell checkbox = grid.Rows[e.RowIndex].Cells[e.ColumnIndex] as DataGridViewCheckBoxCell; // 获得checkbox列单元格
int result = 0 ;
if (checkbox != null && checkbox.Value.ToString() == " 1 " )
{
result = cuttingReport.UpdateR_RptRstnStandardAndBlendByCheck( this .reportID,pstnID, 1 , 0 );
}
else
{
result = cuttingReport.UpdateR_RptRstnStandardAndBlendByCheck( this .reportID, pstnID, 0 , 0 );
}
if (result < 1 )
{
MessageBox.Show( " 修改失败" , " 提示" , MessageBoxButtons.OK, MessageBoxIcon.Error);
}
}
} }
另外：grid.Columns[e.ColumnIndex].Name == "Check" 中Name的值，是在生成DataGridView的Columns时添加的：
new DataGridViewCheckBoxColumn() { HeaderText = "Check", DataPropertyName = "Checked", Visible = true, Width = 45, Frozen = true, Name = "Check", TrueValue = 1, FalseValue = 0, IndeterminateValue = 0 }
