问题描述

我有一个数据表TblTreeView，它有四列：

I have a Data table TblTreeView which have four columns:

ParentID(pk) | ParentName| LeftChildID | RightChildID

我希望在树状视图中显示所有数据;



如同

like as

ParentName

|

|_LeftChildID

|

|_RightChildID

我用的是

I was using

SqlDataAdapter dataAdapter = new SqlDataAdapter("Select * from tblTreeView", SqlCon);
DataSet dataSet = new DataSet();

dataAdapter.Fill(dataSet);

TreeView1.DataSource = dataSet.Tables[0];
TreeView1.DataBind();
