ASP.NET does have a TreeView control that you can use to display a Treeview very similar to the one you show.
If you require the Checkboxes on each and every Treeview node, but sure to set the ShowCheckBoxes attribute to the appropriate setting (i.e. ShowCheckBoxes="All">
Regarding the nodes themselves, you can bind the TreeView to a DataSource which can either be an ASP.NET SiteMap file or an XML Document. Alternatively, you can programmatically add the nodes yourself in code like so:
TreeNode tn = new TreeNode();
tn.Value = "Cities";
TreeView1.Nodes.Add(tn);
tn.ChildNodes.Add(new TreeNode("Cochin 1"));
[etc. etc.]
