I'm populating a treeview dynamically. On OnTreeNodePopulate I call a sub and populate the Parent nodes. I do not want to populate the child nodes at this time. Upto this point it works fine.
Now I would like the user to click the parent node and then populate the child node. I tried to use TreeNodeExpanded, but that is called for each parent node, so that didn't work.

When the refresh is done the page is on top again so that i need to scroll down again to see the table. This makes it very unusable for the user.

I have a master page containing a tree and 3 dropdown lists. I am populating a context menu on right click of each node, and when clicked on any item of the context menu, it navigates to required pages.
My problem is after navigating to the required page, the selected values from the drop down lists and the selected node from the tree are getting cleared.
I can set the selected values for the dropdown lists by making some properties in master page.
But how do i maintain the selected node?
In my content page, i have got the valuepath of the right clicked node.
Or is there any other way than setting the properties in master page?

I am trying to determine if the user selected a checkbox for each row in a ListView after hitting a submit button. If so, I need to get the record ID and one other piece of information from that row to insert their selection into a table. I would use a GridView but the questions must be grouped by their categories with the category names displayed followed by their corresponding questions (from what I've read ListView makes this easier).
I tried the code in this forum posting

The problem I am encountering so far is that it keeps returning null even if the Checkbox is checked.
Here is my code:
foreach (ListViewDataItem lvi in lvQuestions.Items)
{
// Find the checkbox in each row
CheckBox cb = (CheckBox)lvQuestions.FindControl("cbQuestion");
// If the checkbox is ticked
