I am generating Textboxes dynamically on selection of treeview node.

I am using a treeview control. I am buliding the tree dynamically. sometimes the tree becomes larger and the down scroll bar is need to see the entire tree. user can select a node from the tree. if one node is selected ,i change the color of the node from server side.
my problem is that if a user selected a node which is bottom in the tree(means, the user used the down scrollbar to see that node), after postback it shows the top of the tree.to see the selected node the user need to use the down scroll bar.
I need to show the selected node after postback. How can I do this?

Why does microsoft make objects in .NET with incomplete behavioural methods, then expect everyone to use a client side "language" to help complete the methods? I don't wanna have to use Javascript to keep focus on my leaf node in my TreeView after clicking it. I want a server side answer to my question, but if that's impossible I guess I can run ANOTHER javascript bandaid to do this, since I guess Microsoft doesn't have a solution. Oh and By the Way if your going to post an answer please remember I'm using WEBFORMS not WINFORMS. God help people who try to run my app (or any .net app) and don't have Javascript enabled on thier browsers. Does Microsoft own Javascript? Maybe since they rely so heavily on help from the client side to achieve behaviours, they ought to think about acquiring it.

I am trying to add some filters to a gridview that I am working on, and I'm wondering if it is possible to generate links or buttons above the gridview based on the years returned in the dataset. For example, if my dataset contains dates from 2001, 2009, and 2031 in my date column, I would like to be able to take that data from my SQL query (getting a distinct list of years is not an issue), and generate the buttons. From there, I would filter the data in the gridview based on the user clicking the buttons.
Is dynamic generation of buttons possible in ASP.NET? I do have some other ideas of how to accomplish the same functionality, but I would prefer to do it this way.

View 3 RepliesI have a code that load hierarchy( nodes) into trew view.. by selecting different date, the hierarchy result from SP will show in the treeview..

it;s like the new result node is appended to existing node.. instead of refreshing the node and showing only the new result. How can I clear out the treeview nodes before adding new nodes from different date?
