I have an aspx page that contains text boxes to hold a
large number of patient data. Some of these text
boxes are parameters for the select statement. When
the user enters data into one of the parameter boxes
and clicks the "Search for Patients" button, the
results are returned in a listbox below. The listbox
contains only a few of the identifying fields for the
patient as opposed to the text boxes that have
everything. I am using a datatable to fill the
listbox. This part works fine.

What I would like to have happen is that when the user
selects one of the items in the listbox, the
corresponding textboxes are filled with the
appropriate information.

What is happening is that when an item in the listbox
is selected the rows in the datatable are lost. What
is the best, (or any), way around this?


My code is listed below:
