Where can I find sample code for displaying FAQs using RadTreeView ?

[gs1711]

In my table I have columns named Ques, Answer, ID, etc. If I want to display these question answers on my page using RadTreeView, how do I implement this ? Like I want the parent node in the TreeView to be the question and child node should be the answer. Any sample code for that in here ?

Hello gs1711,

You can not directly bind the table to treeView. You need to change the relation a little bit. For example you can create a table with the following structure:
  - Column: Id (primary key, int);
  - Column: ParentId (foreign key pointing to the Id of the same table, int, but nullable - the root nodes need to have null for this column);
  - Column: Text (varChar(x), the text that the node should display - i.e. question or answer).

Then having this table you can bind it to the TreeView as follows:

treeView.DataTextField = "Text";
treeView.DataFieldID = "Id";
treeView.DataParentID = "ParentId";
treeView.DataSource = dataTable;
treeView.DataBind();
