XML To TREE VIEW

Use the Following Function to construct Treeview with the help of xml file.

public void XMLToTreeview(TreeView treeView, string fileName)
{

XmlTextReader reader = null;
try
{
// disabling re-drawing of treeview till all nodes are added
treeView.BeginUpdate();

reader =
new XmlTextReader(fileName);

TreeNode parentNode = null;

while (reader.Read())
{
if (reader.NodeType == XmlNodeType.Element)
{


TreeNode newNode = new TreeNode();
bool isEmptyElement = reader.IsEmptyElement;

newNode.Text = reader.Name;

// add new node to Parent Node or TreeView
if (parentNode != null)
parentNode.Nodes.Add(newNode);
else
treeView.Nodes.Add(newNode);

// making current node 'ParentNode' if its not empty
if (!isEmptyElement)
{
parentNode = newNode;
}
}
// moving up to in TreeView if end tag is encountered
else if (reader.NodeType == XmlNodeType.EndElement)
{


parentNode = parentNode.Parent;

}
else if (reader.NodeType == XmlNodeType.XmlDeclaration)
{ //Ignore Xml Declaration
}
else if (reader.NodeType == XmlNodeType.None)
{
return;
}
else if (reader.NodeType == XmlNodeType.Text)
{
parentNode.Nodes.Add(reader.Value);

}

}
}
finally
{

treeView.EndUpdate();
reader.Close();
}

}
