I was hoping to ask you a question about a formatted alert message. I'm currently working on a project where a user makes a bunch of selections from dropdownlists (vehicle year, make, model, mobility device manufacturer, mobility device and mobility device lift) which will be inserted into a sql table as a single record. These selections are for a vehicle compatibility database. In order to eliminate duplicate entries, upon the user clicking the submit button, the code behind is querying the table to ensure the same configuration does not exist. If it does, I want to create an alert message in a red font so it stands out to the user that the configuration already exist. If it does not exist, I still need the alert message but in black font.
Now, I already create the alerts which are highlighted below in yellow, it's the font/color change which I can't figure out how to make it work.
Would you by any chance happen to have any suggestions I could use to make this work?
I greatly appreciate any suggestions you can offer.
Below is my current code. The web page is vb.net 4.0
Thanks
Matt Evans
