Thank you both, but I might be missing something and I don't know what I am doing wrong.
On my web.config I am using <authentication mode="Windows">
On the IIS Authentication there are 3 options
- Annonimous (this is the one enabled so far)
- Forms
- ASP.NET

What should I do?

What you are using over web.config. I guess some text is missing over there.

In IIS there should have Windows Authentication. You need to select it.

User.Identity.Name will be null if no user is logged in (depends on the Authentication mode).

ASP.NET Provider and DAL

Good Afternoon,

I am new to ASP.NET. I am used to C# windows delveloper. In all my previous projects we had a seperate solution to handle the Data Access Layer. This layer had all the logic for logging in and communicating with the database.

How do I move the Login (currently I am using Memberships that is setup in my config file) to the DAL layer? Should it be in the DAL layer?

Thanks for all your help.
Chris

Membership having it own internal implementation. If you want to move membership, you can use DAL for all database related code. Even inbetween DAL and UI, you can put the Business Layer also (BLL).

You're trying to keep seperation of concerns, as you should. The problem is, Asp.Net web applications are very much dependant on app and web.configs, which don't run in class libraries.

I don't use .Net Memberships. I created my own role-based security model (did this before I started using .Net) and created data providers to go with it. Also, I use a ConnectionProviderFactory (returns an IDbConnection) class to maintain connection strings so my Dals can be completely independant from the applications using them.

There are some useful features provided in .Net but if you require more abstraction and extensibility you sometimes need to break-out a little.

Hi
Thanks for your input. Smile | :)

Is it really worth going through all the trouble to implement a DAL layer? What is the cons of creating your own role-based security model? And how much work are we talking about. I am fairly new to ASP.NET. Coded alot in VB.NET and C#. When you did this how many stops did you find along the way?

Thanks

I have searched the web for articles on how to create a custom membership and provider to move this to the DAL layer and have only find articles that do something simular for legacy programs.
Is this not the right patht to go along anymmore?

DALs are still very popular and play a big role in n-Tier design. It's all about seperation of concerns/code maintenance: Your GUI code and your business logic code don't need to understand the database; they don't need to understand SQL, so abstract this kind of code.

There are some really useful, really cool things in .Net but in my opinion, a few of them ignore good practice - putting connectionStrings in the application is one of them. However, it does depend on how scalable your application needs to be. If your app. consists of a couple of forms for a HR dept to add new staff, and isn't likely to grow much then I'd say...yeah...go with .Net Membership and don't concern yourself too much about design patterns, stick your db properties in the app.config/web.config.

It's all about context really. What kind of application are you working on? Is this a team project or is it an app you're doing on your own?

I'll see if I can find some detailed articles for you.

Hi
I agree that placing connection strings in the UI's config in not a very good practice to persue. My project currently is small and it is only me that develops it. But over time it can grew to a couple of 1000 users and we will have to get in other developers.

The whole membership works cool with roles and everything. I will appreciate the articles. Thanks

Custom Validation inside Repeater

I have to validate SSN which will be entered in 3 different textboxes (txtSSN1, txtSSN2, txtSSN3).

1. If SSN1 is entered and other TWO textboxes are left blank, then CustomValidater should raise an error.

2. If all 3 textboxes are blank, then is a valid scenario. return true and save.

3. If all 3 textboxes are entered with values, return true.

As I have these controls in a Repeater, I cann't able to find the controls from clientside. Need help

Regards,
Ravi K. Kalyan

You can validate on OnItemDataBound event of repeater.

What is the problem with that. Repeater actually places the same html that you define in ItemTemplate and AlternateItemTemplate.

You can easily use OnItemDataBound event to find the controls. Inside it write like this:

if(e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternateItem)
{
TextBox tb = e.Item.FindControl("yourserversideiD");
tb.Attributes.Add("onblur", yourjavascript);
}

Like this way you can easily find any serverside control inside Repeater and apply your javascript.

so try this out.. Rose | [Rose]

Guys, Thanks for the reply.

All I need is a client side validation.

Server side is just a matter of 20min for me... I'm looking for a client side validation.

Thanks

Hey Ravi... Believe me.. I was really talking about client side validation in the code above.

onblur is a client side event, I think.

Just place your javascript there. Call the validation javascript from there.
if you pass like this :

txt.Attributes.Add("onblur", "javascript:func(this)")

you will get the txtbox on the function.
Also you might use txt.ClientId to pass the id. Smile | :)

My requirement is to validate the SSN in Save_Click event.

NOT in "Onblur" event.

I also have "Add Child" button using which I'm adding new Repeater.. So I can add N number of children before clicking on save button. And each repeater is having SSN1, SSN2 and SSN3 textboxes that I need to validate.

Thanks for the replies.
Ravi

Ok.. so for each SSN1, SSN2 and SSN3 you will be having one button..

So do like this :

Button btn = e.Item.FindControl("yourbuttonid");
TextBox SSN1 = e.Item.FindControl("SSN1ID");
TextBox SSN2 = e.Item.FindControl("SSN2ID");
TextBox SSN3 = e.Item.FindControl("SSN3ID");
string script = "javascript:validate('" + SSN1.ClientId + "','" + SSN2.ClientId + "','" + SSN3.ClientId + "');";
btn.Attributes.Add("onclick", script);

Now in the page designer, place a script tag and add a function validate:

function validate(ssn1id, ssn2id, ssn3id){
   var ssn1 = document.getElementById(ssn1id);
   var ssn2 = document.getElementById(ssn2id);
   var ssn3 = document.getElementById(ssn3id);

   // do the logic here.
   
}

I home this is what you wanted. Thumbs Up | :thumbsup:

No need to add Columns. Use AutoGenerateColums = true to make the gridview auto generate columns based on data. Smile | :)
