Calling a function in the .aspx.cs code behind file with jQuery load()

So I have something like this situation:

    $(document).on('click', 'a[data-link]', function () {
        var $this = $(this);
        url = $this.data('link');
        $("#imagePreview").load("imageProcess.aspx?" + url);

where url holds GET parameters. But imageProcess.aspx is different than the file I'm in (dashboard.aspx) and I need to reference some panels within my dashboard.aspx file. So my question is, using the .load() function, or even any function that could get the job done, how do I call a function, with GET parameters, in the dashboard.aspx code behind file? I'm fairly new to the .NET framework so I apologize if the question sounds elementary.

In your imageProcess.aspx.cs create a webmethod like:

[WebMethod]
public static string YourMethod(your parameters)
{
//Do Your Work
}

and in your dashboard page, in javascript use jquery to send request your webmethod like:

$.ajax({
type: "POST",
    url: "imageProcess.aspx/YourMethod",
    data: "{parameter1Name:'" + JSON.stringify(parameter1value) + "', Parameter2Name:'" + JSON.stringify(parmeter2Value) + "'}",
    contentType: "application/json; charset=utf-8",
    dataType: "json",
    success: function(data) {
// do your success work, keep in mind that your returned data will be in data.d
    },
error: function(XMLHttpRequest, textStatus, errorThrown) {
// do your failuer work
}
});

I hope it will give you a guidance to achieve your task.

Just to make sure: You are trying to access functionality from a different aspx page than the one you are currently on. I'm not entirely sure if you can do that the easy way by java script. Maybe someone else knows a better way, but the way I would do it is creating ashx service page which will handle your request so you can provide the data you need (in your case an image)
