[CLOSED] Combobox validation
I have to validate a combobox which contains the following values: ("...", "One", "Two", "Three")
I need the selected value to be different from "...", but also when it is valid (different from "..."), I have the tip with message "The value in field is invalid."
Here is my sample code:
Test.aspx.vb
Thanks.
