Treeview C＃与没有parentid的数据库绑定。 [英] Treeview C# binding with database with no parentid.

问题描述

我有类似这样的表格。我创建了一个示例数据库，需要与Treeview绑定。问题是它没有ParentId。而不是在一个步骤过程中它被制作。

I have a similar table like this. I created a sample Database, which needs to be binded with Treeview. The problem is it doesnot have ParentId. Instead in a step process it is made.

dId	step1	step2	step3	step4	step5	dname
1	0	0	0	0	0	drinks
2	1	0	0	0	0	cold
3	1	1	0	0	0	pepsi
4	1	1	1	0	0	zero
5	1	1	2	0	0	light
6	1	1	3	0	0	heavy
7	1	2	0	0	0	cola
8	1	2	1	0	0	zero
9	1	2	2	0	0	light
10	1	2	2	1	0	onelight
11	1	2	2	2	0	twolight
12	1	3	0	0	0	7Up
13	2	0	0	0	0	hot
14	2	1	0	0	0	coffee
15	2	1	1	0	0	black
16	2	1	2	0	0	Espresso
17	2	1	3	0	0	Latte
18	2	1	4	0	0	Cappucino
19	2	2	0	0	0	Tea
20	2	2	1	0	0	Ginger
21	2	2	2	0	0	Lemom
22	2	2	3	0	0	Mint
23	2	2	3	1	0	Peppermint
24	2	2	3	2	0	Normalmint
25	3	0	0	0	0	hotcold
26	3	1	0	0	0	water
27	3	2	0	0	0	lassi
28	3	2	1	0	0	Mango
29	3	2	2	0	0	plain

我尝试过：



我是WPF的新手，treeview是如此新的概念。我无法从哪里开始。我学习了分层数据模板。但我不知道如何使用这个数据库。我找不到类似这样的合适解决方案。所以只有我在这里发布问题。

What I have tried:

I am new to WPF and treeview is so new concept. I couldn't where to start. I learned about Hierarchical data template. But I don't know how to work with this database. I couldn't find a proper solution similar like this. So only I am posting the question here.
