推荐答案

在RowDataBound事件中:
1.查找行类型为Header
2.找到后，使用FindControl并获得复选框.
3.将找到的复选框强制转换为本地复选框变量.
4.现在，使用此复选框可以做任何您想做的事情.禁用它.

完成.

样本:

In RowDataBound event:
1. Look for row type as Header
2. Once found, use FindControl and get the checkbox.
3. Cast the found checkbox into local checkbox variable.
4. Do whatever you like with this checbox now. Disable it.

Done.

Sample:

void GridView1_RowDataBound(Object sender, GridViewRowEventArgs e)
{
    if(e.Row.RowType == DataControlRowType.Header)
    {
        // This is header row
        // You need to put null checks as per need
        CheckBox cb = (CheckBox)e.Row.FindControl("myCheckBox");
        cb.Enabled = false;
    }
}
