Very simple asp.net question
Originally posted by : BeginnerI am a beginner, I installed asp.net v1 and it seems to work right.I bought a wrox book: beginning asp.net with c# and this is the code from them but it seems to be not working for me....here it is void Page_Load() { if (Request.Form["list1"] != "") { message.Text = "You have selected " + Request.Form["list1"]; } } Drop Down List Example Which city do you wish to look at hotels for? Madrid Oslo Lisbon THE problem:the label "You have selected " keeps getting displayed on the 1st time the page is loaded when nothing from the list has been chosen.Can someone tell me why?I have tried the VB.net version of it, it works correctly.
