Hello Mr.Daban，

您可以通过使用.net控件来访问gridView的rowDataBound事件的任何控件值/>
以下代码是c＃语言

Hello Mr.Daban,
You Can access any control value on rowDataBound event of gridView by using .net control
below code is in c# language

protected void YourGridView_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            if (e.Row.Cells[0].Text == 0)
            {
                ((CheckBox)e.Rows.Cells[1].Controls[0]).Checked= true;
            }
             else  if (e.Row.Cells[0].Text == 1)
            {
                ((CheckBox)e.Rows.Cells[1].Controls[0]).Checked= false;
            }
        }
    }

如果您的单元格确实是复选框单元格，则值不是0或1，它们是布尔值。



您可以对问题中的所有单元格执行此操作：

If your cells are really check box cells, the values are not 0 or 1, they are Boolean values.

You can do this to all the cells in questions:

DataGridViewCell cell = // some cell of the runtime type DataGridViewCheckBoxCell
cell.Value = !((bool)cell.Value);

如果必须，可以检查单元格的运行时类型，或者，更好的是，属性 DataGridViewCell.ValueType ，以确保您正在使用单元格或适当的类型。

If you have to, you can checkup either the runtime type of the cell, or, better, the property DataGridViewCell.ValueType, to make sure you are working with the cell or appropriate type.
