problem with own defined procedure

[Chris]

Hi,

i have a formview in Insert mode.
when a new record is inserted, the text of a textbox becomes: "ok".
Instead of using the ItemInserted or ItemInserting, i use my own procedure
like this:

Protected Sub myproc((ByVal sender As Object, ByVal e As
System.Web.UI.W ebControls.Form ViewInsertedEve ntArgs)
TextBox1.Text = "ok"
End Sub

aspx file:
<InsertItemTemp late>
......
<asp:LinkButt on ID="InsertButto n" runat="server" OnClick="myproc "
CausesValidatio n="True" CommandName="In sert" Text="Insert">
</asp:LinkButton>
......
</InsertItemTempl ate>

But this gives an error (not same signature ...)

This second example works:
<asp:Button ID="Button1" runat="server" Text="Button" OnClick="myproc 2" />

Protected Sub myproc2(ByVal sender As Object, ByVal e As System.EventArg s)
My questions:
1)why does my first example not work and my second does well?
2) how to correct the first example?

Thanks you very much
Chris

The OnClick event doesn't send a FormViewInserte dEventArgs object to the
event handler.

2) how to correct the first example?

Use EventArgs instead, just like in the second example.

Hi, thanks for replying..
It works now (of course).
One more remark:
I guess what the OnClick sends to the procdure is function of the clicked
object, right?
But how can i know what the OnClick sends to the procedure? Does it exist a
list of that for each clickable control or something ..?

For instance: a click on an Image_button like here, what does that send to
the procedure? mean: how do i have to make the declaration of the
procedure?
<asp:ImageButto n ID="ImageButton 1" runat="server" OnClick="myproc "
ImageUrl="~/logos/batman.png" /><br />

Thanks

As far as I know, no Click events send any extra information to the handler.

But how can i know what the OnClick sends to the procedure? Does it exist a
list of that for each clickable control or something ..?

If an event is sent any extra information, it will use some other class
than EventArgs.

For instance: a click on an Image_button like here, what does that send to
the procedure? mean: how do i have to make the declaration of the
procedure?
<asp:ImageButto n ID="ImageButton 1" runat="server" OnClick="myproc "
ImageUrl="~/logos/batman.png" /><br />

The easiest way is to use the designer in Visual Studio. If you add the
event in the designer, it will create a method stub with the correct
parameters.

Otherwise you can look up the events in the documentation.
