function getGrid1Values() {
    var gridArray = [

    return gridArray;
}

Q1/ I need to call that from a server side button_click event, and retrieve the returned array. Can someone show me how to do that?

Q2/ I want the function to return array()(), i.e. an array of arrays, and not a 2D array...

[sapator]

Very bad practice and not sure it can be done on button server event.
I'm under the impression that it can only be used on the load event registerclientscript or something like that.
Let me take a look...

OK, if ever, like here but other than that it's still a very bad idea. You should be using some call (like Ajax) to send what you want on the server side and let it do what it must do.

Q2 I'm very bad with arrays.

[.paul.]

Problem is the button must be run server side. The grid tds, I can display them in page_load, but there’s no way to retrieve user input on the server side. I need to retrieve values on form submit, but I still need the array server side.

Of course there is a way to retrieve user input server side. Call a web service in whatever implementation you want , including the javascript data in Json.
Else, what are you gong to do here? You are stuck.

I'm trying to save the array as a JSON session variable now. I think my array is badly formed. Can you see any way to fix that?

What is the array output?

[.paul.]

I’m still unsure about that. That’s my next step… testing the Array and the JSON string

[sapator]

OK.
I think someone, if not me, will be able to help on the array issue.

I finally got it working. I can handle onclick for server side alongside onclientclick in javascript clientside which runs first. I’ve been able to do what I wanted through page_load and postbacks. I’m pleased with the progress now, after exploring too many dead-ends…
