I have a button in a grid that I created programmatically. The button edits some data in a table using data in a hidden column of the grid that the button is in. Normally I send a hidden field the row data using javascript onclientclick of the button then make the changes to the database using that hidden field. But there must be a way to send the addhandler of the button a parameter. This is the code i have to clarify....
Dim btnedit As New ImageButton
AddHandler btnedit.Click, AddressOf btnedit_Click
btnedit.ImageUrl = "imagesttnEditMini.gif"
From what I understand, when you use AddHandler you're not actually calling a Sub, so you can't pass a parameter. I'm confused on what to do though about this. I've just populated a DataGridView and added a button to it in the codebehind. I'm then using an AddHandler to add a click event to the button. So when I get to the click event, I need to be able to access to the datagridview because clicking the button takes data from the datagridview and loads it into excel. What would I do about this. This is my Method where DataGridView was just populated
Dim btn As New Button btn.Name = dgv.ToString() btn.Location = New Point(0, 0)

I created a Console Application, with a Sub Main(Byval str As String), and when I run the debugger I get the following error:Error1No accessible 'Main' method with an appropriate signature was found in ...
Also I'd like the solution to my problem to apply not only to the debugger, but also to the .exe file that will eventually be created.Also, I found the following code on the internet, but I don't understand how to send the parameter in still.
Public Sub Main() MsgBox Command$,vbOk, "Command Line params" End Sub

When I include () in the AddressOf, VS complains: 'AddressOf' operand must be the name of a method (without parentheses).
When I exclude the brackets, VS complains: Method '...' does not have a signature compatible with delegate...
One of the things that I think is really cool about VB.NET is how built-in functions and subs have extra help text in their ToolTips like "Expression: String expression to search for replace string." as well as the usual "Replace(...parameters...) as string" text. So are the pop up boxes with things like "CompareMethod.Binary" or "CompareMethod.Text." And finally I like how some functions and subs have different sets of parameters for the same routine. For example, New FileStream() starts with either a path (string) parameter or handle parameter, but none of the 15 sets of parameters contain both path and handle parameters. Is there a way that I can set up the classes and functions I write to use these things or do they only work with built in classes and functions? If there is a way, what are the proper names for them so I can look them up in the VS/VB documentation? I would be happy enough if someone would give me an example of them, but it would be nicer if I could go through the documentation and find out if there are other cool things that are related or near by.
I can't figure out why my addhandler is not firing?In the Sub "CreateTagStyle" the AddHandler is not firing when the LinkButton is clicked Is there some reason that addhandlers can't be added at certain points of the page lifecycle?

I am creating a dropdown list in code for a gridview. I want to create an addhandler so I can have access to the selectedvalue. However, here (Rowdatabound) the add handler does not get fired off. How should I go about this?

I have a number of UserControls that have the same event .
When I use an Object instead of UserControl, I can not use Addhandler.
Here is the simplest example of my problem: In this example error is "TextChanged is not an event of Object"
Dim obj As Object = TextBox1 AddHandler obj.TextChanged, AddressOf text_changed_event I have to use this structure, because in a FOR loop I use some different UserControls as obj. All UserControls have the same event.
Is there a way to use this structure without error?
Maybe there is a way to define a new object that covers all my UserControls.

The addhandler function works this way: AddHandler Button1.Clicked, AddressOf Button1_Clicked, However, I have an unknown object: Dim o as Object, But I can't add handler for this object AddHandler o.SomeEvent, AddressOf SomeFunction, How do I add handler for unknown objects as stated above?
been banging my head against this problem for days now. Hopefully somebody could point me in the right direction =) I have some button functionality in my Master Page:

I'm trying to add a handler, but as soon as I'm targetting a method that has parameters, the handler fails. This is the simple code:
