Check whether ur listbox propery "AutoPostBack" is enabled or not. If it is False, change it to true. then it will work

Please specify more accurate information about your problem.

If the page is not posting back when a selection is made, make sure the AutoPostBack property on the control is set to 'True' on all the ListBoxes.

if (Membership.GetUser() != null)

Hi,
I can't understand, why this line is not working:

if (Membership.GetUser() != null)<br />
            Session.Add("current_user", Membership.GetUser().UserName);<br />

I used this code in my another program, and it works pretty good, but not in my new program. It is just never "true", even when the user is logging in.

Do you know what's wrong?

thanks

1. Membership.GetUser() will only work for an authenticated user. Otherwise, it's going to return null. To verify you're dealing with an authenticated request call "User.Identity.IsAuthenticated" on the page. If you've got an authenticated request, but Membership.GetUser() is still returning null, then that means the username associated with the authenticated user can't be found in the Membership datasource. Verify the username of the authenticated user with "User.Identity.Name".

2. If you're calling one of the Membership.GetUser() overloads which takes the username and it's returning null, then that user doesn't exist in the Membership datasource (or we've got a bug). One way to easily verify this is to try a Membership.CreateUser() with the same username. If this doesn't throw an error because of a duplicate user, then you know the user never existed in the first place.

3. Membership.GetUser() should have never worked for an anonymous user. No support was built into Membership for handling this case.

Hope this helps.

ICallbackEventHandler Help

Fayu1-Dec-07 11:19

1-Dec-07 11:19

I am trying to create a WebControl using ICallbackEventHandler. Here is what im trying to accomplish:

-I want to have an autocomplete textbox control.
-After the third letter is typed, the textbox will hit a datastore on the server and retreive availible options.
-I want to be able to allow a Customers property which will be used to bind the textbox autocomplete to the Customer.ID property.

<code>
public class TextBox: TextBox, ICallbackEventHandler
{
       private Customers[] m_Customers;
       public Customers
       {
          get{return this.m_Customers;}
          set{this.m_Customers=value;}
       }
}

public class Customer
{
       private long m_ID;
       public long ID
       {
          get{return this.m_ID;}
          set{this.m_ID=value;}

       }
}
</code>

Any suggestions?

AFAICS, you haven't implemented the ICallbackEventHandler interface and you haven't written the Javascript plumbing code that initiates the callbacks from the client. You should read the MSDN documentation to learn how to do this.

IMHO, you would be better off using the ASP.NET AJAX framework to do this. The ASP.NET AJAX Control toolkit includes an AutoComplete control. You can view its behaviour here[^].

I could use the ASP.NET AJAX Framework but then i would never learn what is going on in the background. Call me ole fashioned, but i like to know how things work and customize it accordingly. Dont get me wrong, the whole ASP.NET AJAX Framework is terrific, but i want tobe able tocreate all that on my own. Can you give me a simple sample on how touse this interface?

I don't have any code to hand. As I previously stated, the MSDN documentation contains all the information you need, including a sample[^] implementation.

I still think you are better off using the ASP.NET AJAX framework. Writing the Javascript plumbing code to get the client-side callback stuff to work is pretty tedious and takes up time that could otherwise be spent doing more interesting stuff. The AJAX Control Toolkit download comes with source, so you can look at the implemention of the AutoComplete control and modify the code if you need to.

Display Category Hierarchy

Brendan Vogt1-Dec-07 7:52

Brendan Vogt

1-Dec-07 7:52

Hi,

I have a categories which can have multiple child categories, and each child category can also have multiple child categories.

I want to display all the categories with their child categories right down to the lowest level hierarchy like:

Level 1
Level 1.1
Level 1.1.1
Level 1.1.2
Level 1.1.2.1
Level 1.2
Level 1.2.1
Level 1.2.2
Level 2
etc. etc. etc.

Is their a .NET control that does this? If not how would I go about it? Any sample articles would be appreciated. Does the repeater control not do something like this?

Regards
Brendan

What have you tried?

It isn't acceptable to post messages on the forums asking for code without demonstrating that you have made a serious attempt to solve the problem yourself. I suggest you search Google and buy a book.

Agree totally. What is so hard about trying and getting stuck, then asking?
