Setting a label = to something kind of as a messagebox

[jtr9999]

Im creating a web application with vb.net in asp and i am trying to have a label appear when the first part of the if statement is false. Here is what i have and it doesnt work.
If listbox1.selectedindex = -1 Then
Label.text = "Please select a name in the listbox"
Label.text.visible = True
Else

if this was a winform, it'd work, but since it's asp i dont know why it doesnt work

I can't see why it would'nt work either but instead of making the text visible why not the whole label?

hi
I assume that the code you wrote is behind a button click.
As Vis781 already mentioned, you need to make the label visible and not the text of it.
Just set the labels property of visibility to false at "page load" and do the next behind the "button click"-event:

If listbox1.selectedindex = -1 Then
Label.text = "Please select a name in the listbox"
Label.visible = True
Else
