What help do you need. all you provided was some sample code. No detailed question, no error information??

[Pennie_1]

I'm not getting an error. Nothing happens after I hit the search button. This is the code I'm using for my application. Here's the background on the application. The user will enter data on one page and submit. The data is stored in my table I created in mircosoft sql-database. The user then should be able to go back search with last name, first name, or SSN it should retreived that data and display in a gridview that also allows user to edit, delete, and re-save.

Did you copy this code from somewhere? it seems to be incomplete and doesnt seem to be correct.

For example, without actually validating your code and just briefly scanning it, I see that you are building a SQL query, but you dont seem to execute it, then towards the bottom you are trying to bind something to the gridview, but that doesnt make sense regarding your the top portion of the code.

I wrote it. The bind part came from trying different suggestions after researching different websites. Can you advise me with what I should do? What I need to add or delete? Thank you for responding.
