使用 Radiobuttonlist 绑定嵌套的 Gridview

Question

我有一个嵌套的Gridiew。父级显示customers，子级显示customer 的每个部分。

有关信息：
grdViewCustomers 显示customers。
grdviewordersofcustomer 显示每个customer 的部分。

在ChildGridview 我有一个RadioButtonList，所以你可以选择它是什么零件类型。

我在.cs 中有ChildGridview 和使用grdviewcustomers_onrowdatabound 的父数据绑定。

我可以从RadioButtonList 获得价值。但是我无法从 SQL 中提取数据并在页面加载时设置为适当的值。有人可以帮忙吗？我感觉很接近，但还没有金子。

protected void grdViewCustomers_OnRowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        string customerID = grdViewCustomers.DataKeys[e.Row.RowIndex].Value.ToString();
        GridView grdViewOrdersOfCustomer = (GridView)e.Row.FindControl("grdViewOrdersOfCustomer");
        grdViewOrdersOfCustomer.DataSource = SelectData("select * from [dbo].[View_Budget_Setup_2_Items] WHERE CUSID='" + customerID + "' order by id_item");
        grdViewOrdersOfCustomer.DataBind();

        foreach (GridViewRow rowChild in grdViewOrdersOfCustomer.Rows)
        {
            string ChildID = grdViewOrdersOfCustomer.DataKeys[rowChild.RowIndex].Value.ToString();
            string Editable = dbUtilities.SalesEditableID(ChildID);

            if (Editable == "Bud")
            {
              // Set values here

            }
        }


        grdViewOrdersOfCustomer.DataBind();
        //testing
    }
}

ASPX 端

您应该将每个内容的代码移动到 grdViewOrdersOfCustomer GridView 的 onrowdatabound 事件中，以便在绑定之后获得每一行。

protected void grdViewCustomers_OnRowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        string customerID = grdViewCustomers.DataKeys[e.Row.RowIndex].Value.ToString();
        GridView grdViewOrdersOfCustomer = (GridView)e.Row.FindControl("grdViewOrdersOfCustomer");
        grdViewOrdersOfCustomer.DataSource = SelectData("select * from [dbo].[View_Budget_Setup_2_Items] WHERE CUSID='" + customerID + "' order by id_item");
        grdViewOrdersOfCustomer.DataBind();

    }
}


protected void grdViewOrdersOfCustomer_OnRowDataBound(object sender, GridViewRowEventArgs e)
{

       if (e.Row.RowType == DataControlRowType.DataRow)
        {

            string ChildID = (GridView)sender.DataKeys[e.row.RowIndex].Value.ToString();
            string Editable = dbUtilities.SalesEditableID(ChildID);

            if (Editable == "Bud")
            {
              // Set values here

            }
        }
}

作为绑定单选按钮列表，您可以像这样在 aspx 代码上执行此操作：

<asp:RadioButtonList ID="RadioCusListC" runat="server" SelectedValue='<%# eval("CollumnName")%>'>
                <asp:ListItem>DNB</asp:ListItem>
                <asp:ListItem>B/G</asp:ListItem>
                <asp:ListItem>B/O</asp:ListItem>
                <asp:ListItem>BUD</asp:ListItem>
            </asp:RadioButtonList>

请记住，如果您获得的值不是来自查询的值，您将得到一个错误。

你还冷在 grdViewOrdersOfCustomer_OnRowDataBound 上找到控件并执行此操作：

RadioCusListC.Items.FindByValue(Editable).Selected = [True]
