OnClick - Method With Databind

[Jl_G_0]

Hey all. hope someone can give me a little advice here.
I have a GridView, and on each line of it there's an
<asp:imagebutto nlike this:

<asp:ImageButto n ID="hlCancel" runat="server" ImageUrl="/details.png"
Width="10px" Height="10px" OnClick=<%#
showDetails(Htt pUtility.HtmlEn code(Convert.To String(Eval("id "))))
%/

The thing is, I need the OnClick event on each line to call the
method showDetails with the ID related to it, like showDetails(LIN E
ID), but this binding tag, while working normally on normal fields
(like label's TEXT) doesn't work here.
I think the error is CASTING related... but Im not sure. I also
tried
to create a function to return the string "showDetails(id )", but it
gives me an InvalidPostback error...

Anyone have a tutorial or lessons on binding with functions/methods ?

Use the standard events rather than trying to kludge this together. There
are plenty of tutorials on the web on getting the ID from a postback,
without attempting to call a custom server side event.

if you must have a call that is fired onClick, you can do something like the
following;

the OnClick is a serverside event for which you cannot change the signature.
the property is expecting the name of a function (with the proper parameter
list),

if you where trying to call client script, see the OnClicntClick property.

thx. I'll have a look at these links. The reason I wanted to do this
its because I tried to do several functions inside the same aspx page,
with UpdatePanels and dynamic stuff. I was avoiding postbacks and pop-
ups to show details...

Working now - just reporting what I did, maybe someone will need:

The method gets the sender AND its CommandArgument , since the
CommandArgument is a string, it can be bound to the ID field. So the
method gets the sender and then the ID of the gridview element.

void showDetails(obj ect sender, EventArgs e)
{
//HERE I CREATE AN INSTANCE FOR THE BUTTON
ImageButton bot = (ImageButton)se nder;
//NOW YOU GET THE COMMAND ARGUMENT
string argument1 = bot.CommandArgu ment.ToString() ;
//AND FINALLY YOU CAN USE IT THE WAY YOU WANT
string sql = "SELECT * FROM tbl01 WHERE id=" + argument1;
......
}

Here's the code for the button, OnClick calls the method above,
CommandArgument is bound to the ID field of my database:

<asp:ImageButto n ID="hlCancelx" runat="server" ImageUrl="~/
details.png" Width="10px" Height="10px" OnClick="showDe tails"
CommandArgument ='<%#
HttpUtility.Htm lEncode(Convert .ToString(Eval( "id"))) %>'/>

The downside: I had to switch EnableEventVali dation to "false" on the
page... but I think it can't be helped...

Thanks for the help, I researched based on what you guys told me.
