Seat reservation program
Jan 23, 2013 12:13 PM|j0zef|LINK
Hello,
I would like to make a seat reservation program with a access database.
I have 150 seats I use 150 buttons for this.
In my database ik have a columm seatnumber from 1 to 150 and I have a columm booked with "0" and "1" values: 0 = free 1 = booked.
In my page_load i want to make a query that looks which seats are booked en which seats are free.
The free seats buttons are green and the booked are red.
so thats my problem I cant find the qeury that the buttons change the colors.
Can someone help me?

Take a look at this link: http://forums.asp.net/post/5268934.aspx
This was a thread I was part of recently and it sounds like you want to do something similar.

So, how are you generating this layout you show in the picture? The code that generates the grid you are showing, can you show us that?

You could post the page's HTML so we can see what the html is doing.

See where it says Zitjes.aspx.vb? We need to see that file. Can you post what you find in there? There has to be something in there.

j0zef, we want to help you but you have to help us by posting your code behind page. We don't know what your page is doing based on the HTML alone.

Hi j0zef,
Button in asp.net really has the property of BackColor，and Is your Button of a List?

But that's not a list or a collection of Button……
If you insist doing so，you have to create a List<Button>，and then use your codes.

Hi again,
Just create a List(Of Button), and then dynamically add Button to the List instance and show the Button onto webpage.
