推荐答案

在单击控件的 CheckedChanged 事件中执行此操作，您还可以获得单击控件的当前行，您也可以从同一行中找到其余控件.

do it in CheckedChanged event of clicked control, you can also get current row of the clicked control, and also you can find the remaining controls from the same row.

最后，我得到了解决方案....

在CellValidating事件上编写以下代码，

Finally i got solution for this....

write following code on CellValidating event,

int column = e.ColumnIndex;
            int row = e.RowIndex;
            if (column == 2)
            {
                DataGridViewCheckBoxCell c = dgv1[e.ColumnIndex, e.RowIndex] as DataGridViewCheckBoxCell;
                if (c != null)
                {
                    string a = e.FormattedValue.ToString();
                    if (a == "True")
                    {                       
                        dgv1.Rows[row].Cells["column2"].Value = false;
                        dgv1.Rows[row].Cells["column3"].Value = false;
                    }
                    else
                    {                        
                        dgv1.Rows[row].Cells["column1"].Value = false;
                        dgv1.Rows[row].Cells["column2"].Value = false;
                        dgv1.Rows[row].Cells["column3"].Value = false;
                    }
                }
            }

重复其余列的代码........

repeat the code for remaining columns........

DataTable dt = new DataTable()
foreach(dt.Rows中的DataRow行)
{
如果(row ["gridviewcheckboxcolumnname"].ToString()==真")
{
//您的代码
}
}

DataTable dt = new DataTable()
foreach (DataRow row in dt.Rows)
{
if (row["gridviewcheckboxcolumnname"].ToString() == "True")
{
//your Code
}
}
