What does the Login control look like?

Bob

 

by: stanvickersPosted on 2006-12-29 at 13:44:27ID: 18216579

Hi Bob,

I'ts just a basic login control for asp 2.0 / visual Basic 2005 - it shows "user Name", "password", "remember me next time" (checkbox) and a "log in" button  

Here is the asp for the login control:
    <asp:Login
        ID="Login1" runat="server">
    </asp:Login>

Also asp for the other two buttons:
    <asp:Button ID="Button1" runat="server" Text="Button" />
    <br />
    <br />
    <asp:LinkButton ID="LinkButton1" runat="server">LinkButton</asp:LinkButton><br />

Thanks for your help -

I'm going to tinker more on it now to see if I can come up with anything... I have another web site using the same method of SQL Server membership provider and it works fine... go figure.

Stan.

Also on the link button when I don't have the following options in my web.config <pages> secton:

 -->           validateRequest="false" enableEventValidation="false"

I get the following error:
Invalid postback or callback argument.  Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page.  For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them.  If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.

OK - getting closer -- tried a button in the Header which is a user control (ascx)  the button in the header user control works, but a test button in the content area does not work....  Note: using a master page... the header user control is in the master page... The content where non working button is placed is within a "content placeholder", default.aspx page based on the master page...

ANSWER:  Don't have more than one form tag!  

Sorry for those of you who were burning time on researching this.  The answer was right under my nose.  I had included a google search on my header.  I had changed all the buttons to asp because standard form stuff google gives you don't work with a master page asp form kinda thing.  I FORGOT to take out the FORM tag that wraps around the search code... I didn't get any errors on compile, but ASP.Net just decided that the first form was the only form to work with... anyway... sorry for the goose chase..  

Special Thanks "TheLearnedOne" / Bob for taking time to work on this.
