I need some assistance with disabling web control button. First, i need to check if the value related to the button is in the listbox. This is done.
If the item is in the listbox, disable the button. I am thinking the possibility of using a loop statement. However, i do not know how to write it to check if the item related to the button matched before disabling button.

Are you doing this client-side, or server-side?
What do you mean by "disable"? Show, but have no effect when clicked? Or, remove the button completely?
I have difficulty understanding your last sentence. Could you rephrase the question?

Server Side.
I am doing a movie booking page and the seats are represented by web control buttons. They are to be disabled when the seats booked values are listed in a listbox known as listbox_seatsbooked.
From the listbox_seatsbooked, it is suppose to check if the value of the button matches the ones listed in the listbox to disable the button from being clicked again. (Seats can't be booked) again.
I have included an image of how it looks for better clarifications.

' Disable the Add button if the ListBox control already contains the item.
Dim name as string
Dim item As ListItem = listbox_seatsbooked.Items.FindByText(name)
If Not item Is Nothing Then
a1.Enabled = False
Else
a1.Enabled = True
End If

Hi f1_fan, thanks for ur assistance.
I cannot find a declaration known as .tag in asp.net (codebehind vb.net). I tried using C# converter to VB.net.
Any suggestions?
