C# gridview标题模板中的foreach复选框

我有一个动态gridview，标题有多个复选框。是否有一种方法可以让复选框单独执行以下操作：

protected void gvUsers_OnRowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.Header)
        {
            foreach (CheckBox cb in e.Row.Controls) //<- is there something like this?
            {
                cb.Attributes.Add("onclick", "javascript:SelectAll(this);");
            }
        }
   }

因为ID是动态生成的

您可以使用：

e.Row.FindControl("checkboxID"); 

var allCheckBoxes = e.Row.Cells.Cast<DataControlFieldCell>()
    .SelectMany(c => c.Controls.OfType<CheckBox>());
foreach (CheckBox cb in allCheckBoxes)
{
    cb.Attributes.Add("onclick", "javascript:SelectAll(this);");
}

var allCheckBoxes = from cell in e.Row.Cells.Cast<DataControlFieldCell>()
                    from cb in cell.Controls.OfType<CheckBox>()
                    select cb;
