How to get Gridview to respond to Select command on Blackberry Browser (Curve 8530)

David Mujica19-Jul-11 4:58

I'm trying to develop a Blackberry friendly web page which has aGridview on the page.

I have tried making the row "Selectable" (select hyperlink is shown) and adding command button as one of the columns in the grid. Neither one of those methods respond to a click by the Blackberry Browser.

Does anyone have a solution for this ?

GridView is bulky. I would suggest to use some repeater control, or something light weight and implement the required functionality using JavaScript. Smile | :)

Explain your problem in detail. "Not working" is not a good explanation. Does it give you an error? What is it supposed to do?

ASP.NET Login Control always logged in

I'm creating a website where I'm using a LoginView control. The code for the control is:

<asp:LoginView ID="LoginView" runat="server">
                    <LoggedInTemplate>
                        <asp:Label ID="lblPrivateClassMessage" runat="server" Text="" Font-Bold="true" Visible="false"></asp:Label>
                        <asp:ImageButton ID="imgAddToCart" runat="server" ImageUrl="~/Images/AddToCart.png" Height="40px" Width="119px" Visible="false"/>
                    </LoggedInTemplate>
                    <AnonymousTemplate>
                        <asp:Login ID="MemberLogin" runat="server"  
                        CreateUserText="Create a new user..."
                        CreateUserUrl="~/Members/Register.aspx"
                        PasswordRecoveryUrl="~/Members/RecoverPassword.aspx"
                        UserNameLabelText="E-mail address:"/>
                    </AnonymousTemplate>
                </asp:LoginView>

I haven't created any code to handle registration or logging in yet, but the controls within the LoggedInTemplate are always being displayed. So I decided to add a LoginName control within the LoggedInTemplate to determine what user name the system is saying I'm logged in as. It displays my corporate login name; in the format MYCOMPANY\UserName. Since the website is interactive with our SQL server to manage products and such I am connected to our corporate network through VPN. If I disconnect from VPN I can't test and debug my website, but if I'm connected the website always has me logged in?

What can I do so when I first go to the web site pages, it does not have me logged in so I can test logging in, logging out, etc. The interesting thing is that on a previous site that I made I didn't have this problem, albeit I did not use a LoginView anywhere on the site. Any ideas, suggestions, etc. Thanks in advance for any help you can provide; it is very much appreciated as my company wants this site done in about 2 weeks.

Nevermind...I figured out the issue. In my web.config file I had the authentication mode set to "Windows" as opposed to "Forms".

Hi, Im working with this method. The problem is that Im creating a new page and then try to assing the Header.Title but it will throw and exception of NullReferenceException.

public static string RenderControl(string controlName)
{
Page page = new Page();
page.Header.Title = "New Page";
page.Controls.Add(header);
UserControl userControl = (UserControl)page.LoadControl(controlName);
userControl.EnableViewState = false;
HtmlForm form = new HtmlForm();
form.Controls.Add(userControl);
page.Controls.Add(form);

StringWriter textWriter = new StringWriter();
HttpContext.Current.Server.Execute(page, textWriter, false);
return textWriter.ToString();
}

Same thing if I try to add

HtmlLink myCSS = new HtmlLink();
myCSS.Href = "~/somecss1.css";
myCSS.Attributes.Add("rel", "stylesheet");
myCSS.Attributes.Add("type", "text/css");
Page.Header.Controls.Add(myCSS);

I try to set a new header but It says

page.Header
(Gets the document header for the page if the head element is defined with a runat=server in the page declaration.

but when you see the new Page() constructor it says <No Parameters> Cant set the header with attr runat=server when initialize the page.

Regards

I haven't implemented it ever but I think issue is with your code try this way:

//page.Header.Title = "New Page";
//page.Controls.Add(header);

HtmlHead head = new HtmlHead("head")
HtmlTitle title   = HtmlTitle()
title.Text = "New Page";
head.Controls.Add(title)
page.Controls.Add(header);

response.redirect afetr few seconds

I have a basic login page. when a user is logged in, I want him to be redirected to a page with a success message and after 3 seconds, I want him to be redirected to my home page.
I know that I can use sleep time, but it's not recommended. So what's the best way to achieve it?

Re: response.redirect afetr few seconds

I think you can implement through refresh tag under head section:

You can use the META HTML tag to redirect the user. Below is an example:

<META HTTP-EQUIV="Refresh" CONTENT="10;URL=http://www.yourdomain.com/">

OR
Try with :

Response.AddHeader("REFRESH","10;URL=http://www.yourdomain.com");

You can use Javascript if you want:

JavaScript

setTimeout( 'window.location = "default.aspx";', 3000 );

You can excute that script from anywhere even in your codebehind.

Hope that helps

Hi
I am creating an extranet site which will use windows-based-authentication (Digest Authentication; http://www.codeproject.com/KB/aspnet/ASPDOTNETauthentication.aspx).

My question is; when using WBA a windows login dialog is displayed for users to provide their credentials. Is there a way to use a web form for this without changing the authentication method? Ie: I would like windows to allow/deny access to the site but I want the user to enter their credentials into a nicely CSS formatted page rather than a nasty windows dialog!

Im very new to APS .NET and web design! Please speak slowly and simply; I wont be offended.

Thanks

Extranet site ... meaning it is hosted outside your corporate network. Right ?

I would think you would want to use Forms based authentication if it is a stand-alone website.

I am currently working on a website which will be using Forms based authentication and the ASP.NET membership provider. I am coding my own login pages and user maintenace pages for this application.

Things you might want to investigate.

AspNetSqlMembershipProvider
Membership.ValidateUser
Membership.GetUser
FormsAuthentication.RedirectFromLoginPage

Just some quick search terms for you to investigate.

I'll be glad to help you if this is the direction you want to go.

You cannot replace the default dialog with your own dialog (or webpage). But you can simulate this by using Forms Authentication, a custom login page and Active Directory API. You just have to authorize your users through the AD API.

How to integrate facebook on a site?

Hi there. It might be possible that what I want to ask has already been discussed on another thread. Still I am not sure.
Here is the scenario:
Must develop a web application site in ASP.NET which deals with hotels. So: hotels will come to register on this site. When a hotel will register new rooms or some other action then the application will have to publish that action as a post on their Facebook account.

Q1: Who can tell me which are the steps to make it possible? I created an app for my website, also.

Q2: Can I test this on localhost? We have the domain but has yet no host.

Take one component at a time and work with that. Search for HowTo: on google for that particular component.

Try to implement it. Then when you have tried and get stuck, or have issues come back and ask specific questions. Now a specific question looks like this;

--------
I am trying to integrate [XYZ component] onto my page, however [this is hapening], and i get [this error] at [this line of code]; The code i am using is below;

All right guys...I am sorry if I disturb you.
I will try to explain again my scenario:
We are developing a website which deals with hotels. A hotel will come to create an account on our website. They will register, for example, new rooms. When that happens need to post on their page of Facebook a message.
First question: Is this possible? And how? I created from developer.facebook an app. Then how will the message me sent without having to press a button.(i am thinking for a webservice).
I will come on with other questions...
Thanks in advance, adrian
