C# 如何从嵌套Gridview中的RadioButtonList获取数据

我找不到任何答案，所以我不得不问

我有一个嵌套的

gridview

。我能够拉入父级

Gridviews RadiobuttonList

的数据

但是，我需要帮助从“Child”

gridview

单选按钮列表中提取数据

这是我为
家长使用的

foreach (GridViewRow row in grdViewCustomers.Rows)
    {
        HFCus.Value = row.Cells[1].Text;
       // CheckBox chk = row.Cells[9].FindControl("Edit") as CheckBox;
        //if (e.Row.RowType == DataControlRowType.DataRow) { }
        RadioButtonList rbl = (grdViewCustomers.Rows[row.RowIndex].FindControl("RadioCusList") as RadioButtonList);
        if(rbl.SelectedIndex > -1)


        {
            string radiovalue = (grdViewCustomers.Rows[row.RowIndex].FindControl("RadioCusList") as RadioButtonList).SelectedItem.Value;

            string CustomerID = grdViewCustomers.DataKeys[row.RowIndex].Value.ToString();
            lblTest.Text = radiovalue + "     RadioValue"; //Button Text
            lbltest2.Text = CustomerID + "     CustomerID"; //Customer ID
            lbltest3.Text = HFCus.Value + "     CustomerName"; //Customer Name
        }
        else{}
    }

这对父母很有效

但是，如果我尝试做一个精确的副本，但是对于孩子来说，它不理解ChildGridviews“ID”

它总是在foreach的第一行出错（GRDViewersofCustomer行中的GridViewRow行）

这里是整个按钮点击

protected void Button1_Click(object sender, EventArgs e)
{
    foreach (GridViewRow row in grdViewCustomers.Rows)
    {
        HFCus.Value = row.Cells[1].Text;
        RadioButtonList rbl = (grdViewCustomers.Rows[row.RowIndex].FindControl("RadioCusList") as RadioButtonList);
        if(rbl.SelectedIndex > -1)
        {
            string radiovalue = (grdViewCustomers.Rows[row.RowIndex].FindControl("RadioCusList") as RadioButtonList).SelectedItem.Value;

            string CustomerID = grdViewCustomers.DataKeys[row.RowIndex].Value.ToString();
            lblTest.Text = radiovalue + "     RadioValue"; //Button Text
            lbltest2.Text = CustomerID + "     CustomerID"; //Customer ID
            lbltest3.Text = HFCus.Value + "     CustomerName"; //Customer Name
        }
        else{}
    }

    foreach (GridViewRow row in grdViewOrdersOfCustomers.Rows)
    {
        HFCus.Value = row.Cells[1].Text;
        RadioButtonList rbl = (grdViewOrdersOfCustomers.Rows[row.RowIndex].FindControl("RadioButtonList") as RadioButtonList);
        if (rbl.SelectedIndex > -1)
        {
            string radiovalue = (grdViewOrdersOfCustomers.Rows[row.RowIndex].FindControl("RadioButtonList") as RadioButtonList).SelectedItem.Value;

            string CustomerID = grdViewOrdersOfCustomers.DataKeys[row.RowIndex].Value.ToString();
            lblTest.Text = radiovalue + "     RadioValue"; //Button Text
            lbltest2.Text = CustomerID + "     CustomerID"; //Customer ID
            lbltest3.Text = HFCus.Value + "     CustomerName"; //Customer Name
        }
        else { }
    }  
}

这是ASPX的报告

在定义了GridView的地方，您的aspx标记是什么样子的。。？您是否有客户的
grdViewOrdersOfCUstomer
的id，或者您是否偶然将其命名为
grdViewOrdersOfCUstomer
，我在上面发布了更改。在
grdViewOrdersOfCUstomer
内部，您有
RadioButtonList
。但是，您的代码调用了
FindControl（RadioCusList）
。您是正确的。由于第一行不喜欢“grdViewOrdersOfCustomer.Rows”这个名称，我还没有修复其余的“子代码”。我希望解决这个错误，而不是一路走下去。
