Why won't my datagrid appear?
Hello. Here is my current code, which should display a datagrid, but its not. Let me explain what I am trying to accomplish. I have a drop down list where an account Number is selected and another one that contains territories. The goal is to be able to transfer accounts. Once the user clicks submit, I would like my datagrid to populate with the data that is selected in the stored procedure 'filldatagrid'. Basically the data inserted into the actual table are all numbers, but i want the datagrid to display the actual names. I am using @accountID in the stored procedure to match that item selected from the drop down with the appropriate account number in my accounts table. So, I hope this gives you an idea of what I am trying to do. I just can't seem to get the datagrid to appear.

lbl_error.text = "Welcome to the Account Transfers Page."
