Since it’s largely repetition it should be fairly easy for someone to have built a application that generates the ASPX page to view and edit this data. No need for anything fancy… just display and edit thedata.

I’ve found applications (Visual Studio is one) that does this for a MS SQL database… but does anyone know of an application that generates ASPX pages that interface with a MYSQL database?

I have this issue with ASP.Net where i have to click my link button twice to get my controls to display. Can anyone take a look at my code to tell me why? This is a somewhat urgent request.

My goal is to only show the footer row when one of the linkbuttons are clicked. In the code below, when the Insert_T link button is clicked the entire footer row with drop downs and textboxes (not labels) should display. The footer row displays and I know the data is there, but the controls don’t display until the second click.

I just posted a portion of the vb code since all the buttons work the same way.

thanks!!

VB-Code Behind:

I then tried another approach, I added the table directly from the Server Explorer, configured the defaulted SQLDataSource connection, I set paging to true. I then opened the page in my browser, clicked the button I have on the page to display the gridview’s data(see new code snippet). However, when I click page 2 the gridview dissapears.

That is the problem I’m having. The gridview keeps disappearing when I click a page number. There’s definitely more data to see. I’m sure there’s a solution. I thought I just set the paging to true. But obviously it’s not that simple. (see code snippet below).

Thanks for anyone’s suppout.
