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RadioButtonList，因此您可以选择它的类型。

我在ChildGridview中使用grdviewcustomers_onrowdatabound使用.cs和父databind。

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？我感觉很亲密，但还没有金。

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
    }
}

Answer 1

您应该将每个内容代码移动到grdViewOrdersOfCustomer GridView的onrowdatabound事件，以便在绑定之后获取每一行。

List

作为绑定radiobuttonlist，您可以在aspx代码上执行此操作：

请记住，如果您获得的信息不是查询中的值，那么您将收到错误。

你也可以在grdViewOrdersOfCustomer_OnRowDataBound上找到控件并执行此操作：

RadioCusListC.Items.FindByValue（可编辑）.Selected = [True]

使用Radiobuttonlist绑定嵌套Gridview
