Description:
The
blog post demonstrates how to populate TreeView Control using XML file in
C#.NET.
The TreeView
control has a Nodes collection
with root TreeNode objects. Each TreeNode in turn has its own Nodes collection
that holds more than one child TreeNode.
<TreeNode
object>.Nodes.Add (TreeNode node) method adds a new TreeNode element with a
specified text to the end of the current TreeNode collection.
Procedure:
Step 1: Variables
Declaration
DataSet set = new DataSet(); //To store Tables
from XML Document
TreeNode
parent; //store Main Table Names
TreeNode
child; //store Contents of Main Table
Listing 1
Step 2: XML file contents tables as shown in below
format.

Step
3:
Now retrieve the values from XML File and add it to the Nodes Collection of
TreeView Control.
//Read Contents
of XML Document
set.ReadXml(@"..\..\XMLData.xml");
for (int i = 0; i < set.Tables.Count; i++)
{
//Get
the Name of Main Table
parent
= treeView1.Nodes.Add(set.Tables[i].TableName);
//Get
Contents of Main Table
for (int j = 1; j
< set.Tables[i].Rows.Count; j++)
child = parent.Nodes.Add(set.Tables[i].Rows[j][2].ToString());
}
