Friend  ,I too faced this problem at lot time.
i tried a method and added a ADO control on the form . Connect the control in the code and pass the recordsource i.e ur SQL statement and then set datagrid's datasource using this control.
I think it can solve ur problem . In case u find another solutions please do let me also know abt that.

how to ask a question :
1. speak english
2. use the thread title as a very short summary
3. use the thread body to actually ask your question instead of your boring " "...
4. hope that someone will close one's eyes on this...

You're asking a very general question. One which, just by asking it, tells us you don't understand the basics of developement. It sounds as if your in over your head.
If you don't understand how your data works on paper, no one here can describe it to you.

 HI
CAN ANY ONE TELL ME WHAT IS A "WINSOCK" AND "MAPI" CONTROLS AND THE USES.
ITS URJENT.

MAPI: MAPI is an acronym for Messaging Application Programming Interface. MAPI allows client programs to become (electronic mail) messaging-enabled.
Winsock is an alias for Windows Sockets enables programmers to create advanced Internet, intranet, and other network-capable applications to transmit application data across the wire, independent of the network protocol being used (retrieved from msdn).
I hope it helps,
Marc Soleda.

Hi
I am setting up a simple web form, and for some reason, the controls that I have put on the page are not showing properly. I have 3 labels and 3 link buttons. They are set up in a column, one after the other, all aligned along the left edge. However, when I compile, they all show up as labels, and rather than showing up properly, they show up in a row.
I am pretty sure that it is a simple solution, but I'm stumped.
Any help would be appreciated.

Are they laid out in a table, do they have <br> tags between them, or did you lay them in a column, but not provide any HTML to make them look that way in the browser ?

Hi Christian
Basically, I dragged and dropped the labels from the control list, then the link buttons. In the form layout, they show as 6 controls in 1 column, no table, no
tags. I have never had to use HTML to make them line up before. Whenever I have done this before, the controls have shown up exactly as I placed them in the form layout.

The form layout page is crap, you should never use it, especially in VS2003 ( you didn't say which you're using ).

OK< I am using VS 2002. Another thing, the link buttons are just showing up as text, not as a link. Any ideas ?

Sorry for the multiple post, but this is how the page shows up
Assignment 4 Inventory System Derek Gruenthaler Products Product Sales Employees
The following are labels : Assignment 4, Inventory System, Derek Gruenthaler
The following are supposed to be link buttons : Products, Product Sales, Employees
I'm lost here

First of all, NEVER EVER use the design view again. In fact, you should change the defaults so you never SEE the design view again. The design view on 2002 is crap, it makes a total mess of your HTML, sometimes to the point of breaking it.
Secondly, for a link button to show as a link, you need to set it's target or click event. If you've not set these, they show as plain text ( because they don't know where to link to ). Finally, add that <br/> tag between your labels, and they will show up in a column instead of a row. Tables are the most obvious way to align your stuff on a page, but <br> will work for one column. Also, I believe it's better to use divs, spans and css, but to be honest, I have no idea how that is done.

Welcome to Code Project. I see you're new, and this may well be the most English you've spoken in a single day. So, I'll be polite.
What you've posted is a demand. What I think you wanted to do is ask a question.
And furthermore, MSDN is full of samples to answer this sort of generic question. You should ask here when you have a specific problem.

Hello!
I am developing a cutom module in DotNetNuke.
I have written the correct NameSpace and Assemblyname but I
just keep getting this error in Visual Studio.
Errormessage:
"An unhandled exception of type 'System.MemberAccessException' ocurred

Exception:

----Inner exception: System.MemberAccessException

End Try<br />
End If<br />

End Function
Any help on this error will be much appreciated!

I think the error is perfectly clear. You're trying to create an instance of an abstract class. Abstract classes (MustInherit in VB) must be inherited by another class that provides the implementation code.
You declared your Data class abstract yourself with this line:
Namespace INVID.DNN.Modules.HelloWorld.Data
Public MustInherit Class DataProvider
#Region "Shared/Static Methods"
' singleton reference to the instantiated object
Private Shared objProvider As DataProvider = Nothing
If you want your Data class (bad choice of name too) to be created as a concrete class on its own, you have to get rid of the MustInherit keyword.
