• Re: Validate the "-Select Item-" in a bound DropDownList

  You don't need a button to fire the client-side validation - a DropDownList has a CausesValidation property you can set to true which will cause the page to be validated and cancel the postback if it fails.

• Re: SelectedIndexChanged not firing for DropDownList

  Without seeing the code it's difficult to say what the problem is. Have you tried debugging to see if the code which populates your DropDownList is run again? (I can't really see it being something to do with the ViewState as I've never seen a problem like that before)

• Re: SelectedIndexChanged not firing for DropDownList

  Your new bug sounds like you're adding the ListItems on every postback. Are you doing it within a if (!Page.IsPostBack) section so it only gets populated on the first load?

• Re: ASP can't read the new value of textbox, this was changed on javascript

  Are you checking Page.IsPostBack in the Page_Load event before setting the textbox value, that is: if (!Page.IsPostBack) { if (!String.IsNullOrEmpty(Request.QueryString[ "LatS" ])) { txtLatSouth.Text = Request.QueryString[ "LatS" ]; } } This way the textbox with only be set to the querystring value the first time the page is loaded and not when it's posted back from the button click.

• Re: SelectedIndexChanged not firing for DropDownList

  Have you hooked the DropDownList OnSelectedIndexChanged event up to your method, e.g. < asp:DropDownList ID= "DropDownList1" runat= "server" AutoPostBack= "true" OnSelectedIndexChanged= "DropDownList1_SelectedIndexChanged" > < asp:ListItem Text= "Red" /> < asp:ListItem Text= "Green" /> < asp:ListItem Text= "Blue" /> < asp:ListItem Text= "Yellow" /> </ asp:DropDownList >

• Re: Drop Down List control and RequiredValidator

  [quote user="callan1"]Here's my drop down, with the intial value set to '--' as it is in the db[/quote] Is it definitely the value of the first item that is "--" and not the text itself, that is the TitleIDNo would have to be "--" for your RequiredFieldValidator to work (rather than the TitleDesc).

• Re: Simple Page_Load Question

  You can't change the order of the events, but you could try moving your code from Page_Load into Page_PreRender which should be executed after the Button_Click event.
