My form has one(1) datagridview and 7 textboxes and i need to save info. from the datagridview as well as textboxes into the database. Pls help

I did a search here on datagridview and got 10 PAGES of articles, with a little refining of the search I am sure you will find 1 or more articles to answer you myriad of questions.
It seems obvious that you have no idea about the DGV, try reading some of the articles before peppering the forum with questions.
Never underestimate the power of human stupidity

Can anyone guide me, how to write the code for searching the deatils in alphabetical order like..........
A B C E F G.... Z..
All the alphabets will be in link format like
If u click on 'A' all the names in 'A' as to be displayed maybe using a list box then put all the buttons on the side of it, then the other side will be list view i have the listview working and also added a listbox i can pull the data thru it but i dont know how to tie buttons to it i am using sql server 2005 express hope someone can help me thank you

You would have logic like for example:
- when button is pressed, you get a connection using SQLConnection
- you create a SQLCommand where you fetch the data and you define the condition using SQLParameter
- then you open SQLDataReader
- you loop through the reader and add the data to the list
- close the connection
Also you should use connection pooling in order to have decent performance.

An ocx cannot work without being registered. On Vista and 2008, this requires an admin. There's no way around it.

 I want to add a button in a form and add Click and DoubleClick events for the button,but the code below doesn't work,why?How should I do?
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim btn As New Button
Me.Controls.Add(btn)
btn.Text = "hello"
AddHandler btn.Click, AddressOf btn_Click
AddHandler btn.DoubleClick, AddressOf btn_doubleclick
End Sub
Private Sub btn_doubleclick(ByVal sender As Object, ByVal e As System.EventArgs)
MsgBox("Double click")

Private Sub btn_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyButton1.Click
MsgBox("Click")
End Sub

is not informative. Does not compile? does throw an exception? which one? etc.
why are you handling Click and DoubleClick differently? (there is a "Handles MyButton1.Click" but there is no "Handles MyButton1.DoubleClick")
why do you have two buttons, one called "btn" and one called "MyButton1"???

The Button control doesn't use the DoubleClick event, so it's never going to get fired.

Eh, both are kinda right. There is a double click event, but it's disabled by default through the control styles.
MSDN: By default, the ControlStyles.StandardClick and ControlStyles.StandardDoubleClick style bits are set to false for the Button control, and the DoubleClick event is not raised.
For more information about handling events, see Consuming Events.
Change the control style or extend the button and the doubleclick method yourself.

Actually I do most of my stuff in C#, so that is all right; reading VB.NET is what might give me the jist if not an itch.

Well, we're all "kind of" right. What happens is that Control exposes all the stuff the's needed for DoubleClick to work, including the mouse handler stuff (WndProc mouse messages), the DoubleClick and MouseDoubleClick events and their subscribe/unsubscribe handlers, and the OnDoubleClick and OnMouseDoubleClick methods that fires those events. This entire chain is enabled by default, like you've said, through SetStyle, which just enables the various window message handlers. When the Button class inherits Control, it's constructor disables the StandardDoubleClick style, cutting off all double-click processing.
But, this is all nice and everything, but why would you want to change the behavior of a Button to include the non-intuitive ability to double-click it?

Let's say I create an object of one of my Forms in Class1
Dim _Form as new Form = pForm
And I know for a fact that the form will contain a method (sub) say..
Public Sub DeleteApproved(pObj as object) Implements IDataForm.DeleteApproved
' Do stuff here
End Sub
To ensure that this method is always there, I Impliment a custom interface IDataForm
How do I call this method from Class1?
This doesn't work:
_Form.DeleteApproved(pObj)
Regards!

It doesn't work because the variable you declared is of the type Form (wich doesn't contain that methode)
Declare the variable as a variable of the type of pForm and you should be able to access it
So something like:
'lets say pForm is a form of the type Form1
Dim _Form as new Form1 = pForm
_Form.DeleteApproved(pObj)
A little warning here if you try to assign a other type (like Form2) to the variable _Form you'll get an error.
If you have multiple forms that need this (Form1, Form2, Form3, ...) a possible way to do this would be to make all those forms inherit from a specific form (InheritForm), declare the methode there (overridable or mustoverride) and make _Form from the type InheritForm. Then in all the other forms just override the methode.
Hope this is a bit clear if not feel free to ask more

Hi again Tom, and thank you!

Then in all the other forms just override the methode.
This was the next thing I was about to try, the problem is that depending on which form it is, I want different code to execute within the method.
In form1 I want to call an update service over WCF to say... delete a row from the DataSource that populates my DataGridView on form1.
etc.
etc.

First you might want to look into Luc's solution, could be the answer for you.
If not you can do what you want with intheritance.
Example:
Form1 is the form where all other forms will inherit from
declare the function on this form like:
public overridable function FunctionName (...) as ...
end function
Form2, Form3, ... all inherit from this Form1
here you place:
public overrides function FunctionName(...) as ...
end function
Now when you call the function from your class the code within the functions on Form2, Form3, ... will be excecuted, this code can be completly differant for every form.
On a side note if you place the following in the functions on Form2,Form3,...:
mybase.Functionname(...)
The code in the function on Form1 will also be excecuted otherwise not.

Hi,
the purpose of an interface *is* to call its members, not just to declare them, so try something like:
Dim _Form as new IDataForm.DeleteApproved = pForm
_Form.DeleteApproved(pObj)

This doesn't look right. Isn't it supposed to be:
Dim _Form As IDataForm = pForm
_Form.DeleteApproved(pObj)
