问题描述
大家好，
我在母版页左侧和右侧使用Treeview控件，并使用用户控件按Treeview中的选定节点显示现有产品.例如:
>移动
>三星
>诺基亚
>摩托罗拉
> TV
> Onida
>三星
问题:我想显示所有子产品都位于数据列表"用户控件中的一个父节点下，而其他选定的父子节点也是如此.所有数据都应来自树视图中的SQL Server表以及用户控件.
但是我不知道该怎么办?任何人都可以帮助我从中脱颖而出吗?
您能否提供链接或C#代码(我在ASP.NET 4.0中使用C#)?
Hi All,
I am using Treeview control in Master page left hand side and right hand side using user control to display existing product as per selected node in treeview. Ex:
>Mobile
>Samsung
>Nokia
>Motorola
>TV
>Onida
>Samsung
Problem: I want to display all the child product comes under one parent node in Datalist user control and same for the other selected parent and child node as well. All the data should come from SQL server table in treeview as well as user control.
But I have no clue how to do? Can anyone help me to come out from this?
Could you provide me the link or C# code(I''m using C# with ASP.NET 4.0)?
推荐答案
SELECT *
FROM Products
WHERE ProductName = @prodname
3)读取查询返回的数据，并为所选节点添加新节点.
