Whenever anyone begs for an urgent answer it usually indicates a homework assignment.

So, start here[^] or go back to your tutor and explain that you don't understand. They will help you.

try this these methods. change filter conditions as your datatable columns.

private void CountryTree()
{

DataSet dsLevels = (DataSet)ViewState["DataSet"];
treeEx.Nodes.Clear();
treeEx.Nodes.Add(new TreeNode("India", "01"));

foreach (TreeNode tn in treeEx.Nodes)
{
DataRow[] drlevels = dsLevels.Tables[0].Select();
int i = 0;
foreach (DataRow drlevel in drlevels)
{
tn.ChildNodes.Add(new TreeNode(drlevel["description"].ToString(), drlevel["value"].ToString()));

ChildTreeNode(tn.ChildNodes[i], dsLevels.Tables[0]);
i++;
}
}
}

private void ChildTreeNode(TreeNode childNode, DataTable dt)
{
try
{
DataRow[] dr = dt.Select("parentId=" + childNode.Value);
int i = 0;
foreach (DataRow drlevel in dr)
{
childNode.ChildNodes.Add(new TreeNode(drlevel["description"].ToString(), drlevel["value"].ToString()));
if (dt.Select("parentId=" + drlevel["value"].ToString()).Length > 0)
{
ChildTreeNode(childNode.ChildNodes[i], dt);
i++;
}
}
}
catch (Exception ex)
{
}
}
