you can always use a dataset / datatable, fill it, use a select query to return all the records, count the rows returned, if it's over a certain number then btn.visible = true ?

DataBind() after deleting the record should do the trick

hi,

i don't get you actually. Can you explain how was it base on my code.

[JJCollins]

Well the code would be

ListView1.DataBind()

Basically refreshes the ListView with the current data, so if you've just deleted, you would databind the ListView to show the record has gone and only 1 now exists.

hi,

i'm sorry. i'm totally new to vb.net. where should i add the code on my code. If you don't mine please modify it on my codes. PLEASE !!!!

[JJCollins]

Just before your If statements, ListView1.DataBind()

Which means it will always have the latest data available to it

You don't have to disable your add button just use if ...else statement some thing like this

if listview1.items.count < 2 then
' your code for adding record in listview1
else

messagebox.show("List view is full")

endif

Best Of Luck
