您好，
如果我理解正确的问题，
当您选中其中一个复选框时，另一个复选框
在同一DataGridView行中，应取消选中.
为此，您需要用户的行数和列数
取消选中或选中复选框.
如果它是正确的复选框，则另一个应易于取消选中或选中.
所以，
您需要做的只是(为它创建代码.)
当您找到
时，处理称为CellContentClick的事件
中单元格的行和列数 用户已选中复选框的DataGridView.
此外，您还可以轻松取消选中或选中同一行中的所有其他单元格.
例子:
创建具有3列和最多10行的DataGridView1，
第一列的初始状态已检查，其他所有状态均未选中.
当您取消选中第一列checkBox时，另一个更改状态变为选中状态，
当您选中第一列checkBox时，其他状态更改为未选中.
Program.cs
Hello ,
If I understand the question correct,
when you check one of the checkBox the other checkBox
in the same DataGridView row should be unchecked.
For that you need the number of Row and Column where is the user
unchecked or checked the checkBox.
If it is the right checkBox the other should be easy to uncheck or check.
So,
all you need is to (create code for..)
process the event called CellContentClick when you will find the
number of Row and Column of the cell in
the DataGridView in wich the user have checked the checkBox.
Afther that you will easy uncheck or check all the other cells in the same row.
Example :
Create DataGridView1 with 3 columns and maximum 10 Rows,
first column initial state is checked and all the other are unchecked.
When you uncheck first column checkBox the other change state to checked,
and when you check first column checkBox the other change state to unchecked.

尝试一下.
Try this one.
CheckBox chk;
CheckBox chk2;
foreach(GridViewRow row in GridView1.Rows)
{
chk = (CheckBox)row.Cells[0].FindControl("chkBox");
if(chk.Checked == true)
{
foreach(GridViewRow row2 in GridView1.Rows)
{
chk2 = (CheckBox)row.Cells[0].FindControl("chkBox");
if(row2.RowIndex != row.RowIndex)
{
chk2.Checked == false;
}
}
}
}
希望对您有帮助！
问候，
