Send me an email to n_i_c_k_5_4_5_4 _at_ hot_mail ( minus the underscores of course )
I have a forum app ( hate php and we needed a forums webite for my world of warcraft guild ) that I did in c# thats easy to understand without too many tricks. It has forums and private mail enabled. If you send an email I can give you a password to it.
Send me an email and I'll send you the project and we can discuss what and how I did it. It doesn't use any ADO calls inside the pages.
-- theories --
But, as far as the DAL and BLL.
The class exists in the BLL.
The DAL will return a populated class.
But, this also depends on who you talk to also.
I come from a Java and C++ background and move towards SOA. So I don't believe in any ADO.NET calls anywhere but the DAL.
But, people that stem from VB or other scripting languages will use ADO.NET calls anywhere ( the UI, BLL, and DAL ) and think it's proper.
But, by definition it says that the business layer does not know about the source of the data. So if you do not know the source of data, then how could you use ADO? That is tied directly to the data.
One solution I have seen before is the create a class that extends the IDBConnection and what not. But, this is just a hack to disobey the rules of abstracting the data source which a DAL implies.
And also, since the DAL could be hitting xml, oracle, sql, excel, text files, and other sources I believe the DAL should query the data and based on the class requested populate what data it can. This way the BLL is never concerned with how it got there, it just knows its there. Which is the definition of an n-tiered application.
If you send me an email, I can write a small prototype demonstrating what I am trying to infer. And add a visio document that visually shows what I'm talking about. Tell me if you have visio in the email. If not the can paste the picture into a word document.
Hope this didnt confuse you.

Hi all,
I have an asp.net page that has two panels of which one is not visible. The panel that is not visible is an Ajax:DynamicPanel. I want to display this dynamicpanel on the click of an imageButton but without the postback. Is this possible? I'm also new to Ajax and I thought I can do this with Ajax. Need suggestions.
Thanks
VJ

You could just use an asp:image and it put it in some element with a javascript OnClick event.

Only a server operating system will let you use integrated windows security across a network. Is that your problem?

i've installed sql server 2000 on winXP sp2 prof. The SQL server is working properly.

Are you using integrated windows security?
XP is not a server operating system and therefore you probably can't use integrated security unless you are on the server itself.

Your server name is incorrect. and or your password.
Create a test form and add a data source. Use the IDE to log on to it. Then grab the connection from there.
Its always easiest to let the environment create it for you first.
If you have VS2003 its even easier. Use Server Explorer. Find your table and drag it onto the form. It creates the entire connection object for you. Just open up the code and copy and paste.

i'm using VS2003. I tried your method, it displays the following error.
Login failed for user COMP\ASPNET'.

Did you try dragging the table onto the form?
If so, then that means you need to allow the ASPNET user to query your database
I would use a different user tho

cool.
But, going forward heres what I do if I'm unsure of the logins and server paths
I drag a stored procedure into the web form.
This will create 2 objects ( command and connection ) which you can see below the form.
The go into the code behind and inside the initialize created by the ID is your connection object. Just copy staht string and paste it into your web.config file.
You can also just view its properties in the designer.
Thats one of the tricks they taught in vb 6 and all that.

You can add an html table in an item template. That html table can have as many rows / columns as you want.

In design view right click on the datagrid and select edit template. Or just write out the HTML.

If you're not pulling back to many records then you could load all four query results into one dataSet with 4 datatables. You could cache the dataset or store it in viewstate. Then use a dataview to filter your datatable then bind the list box to the dataview.
