推荐答案

如果我理解正确，您是说复选框值与基础数据不一致?

If I understand you correctly you are saying the checkbox value does not align with the underlying data?

这很可能是因为数据已经更新并且是脏的"，例如它尚未提交到数据源.如果您添加这样的事件处理程序:

This may well be because the data has been updated and is 'dirty', e.g. it hasn't been committed to the datasource yet. If you add an event handler like this:

private void dataGridView1_CurrentCellDirtyStateChanged(object sender, EventArgs e)
{
   if (dataGridView1.CurrentCell is System.Windows.Forms.DataGridViewCheckBoxCell)
   {
      dataGridView1.CommitEdit(DataGridViewDataErrorContexts.Commit);
   }
}

然后应该更新数据源，当您查询单元格时，您将拥有正确的复选框状态.

Then that should update the datasource and you'll have the correct checkbox state when you query the cell.
