Ways to activate JavaScript on a completely dynamic AJAX ASP.NET website

Encountering a dilemma:

I have developed a fully dynamic site with only one update panel on the startpage. All content is generated dynamically through code behind, with different pages as web user controls.

The issue arises when attempting to open two drag-able panels using the Ajax Control Toolkit. Despite wanting to position these panels using JavaScript, the positioning script fails to execute.

It is worth noting that I am still navigating within the first page of the website, hence there is no browser history. Upon inspecting the page source, it displays the code for the login page, which is the initial landing page of the site.

Avoiding any postbacks to prevent altering the page-history, how can I successfully run the required JavaScript for window positioning?

Resolved

Finding a solution, I addressed this challenge by shifting the positioning logic to the server side. I implemented a "Window Manager" to track all open windows on the site. Subsequently, I managed to set the position by including it in the Style attribute of my web user control as follows:

    protected void Page_Init(object sender, EventArgs e)
    {
        PartPanel.Attributes.Add("Style", Position);
    }

    public string Position
    {
        get
        {
            return "position:absolute;left:" + PosX "px;top:" + PosY + "px;";
        }
    }

Answer №1

Can you provide some sample code for reference?

Wouldn't employing a more streamlined approach using a generic handler be more efficient than cluttering up the code behind a webpage? It may help reduce unnecessary overhead as well.

You might want to explore Chrome's developer tools or Firebug for Firefox to examine the source code and manipulate the DOM. These tools also offer additional features like a JavaScript console for logging errors.

Answer №2

 function goToPage(mshtml.HTMLWindow2Class JSFile) {
        target = JSFile;
}
function printScript(){
        window.execScript("alert('Printing is done!')", "JScript");
}

or

Page.RegisterStartupScript("myScript", "<script language=JavaScript>sayHello('" + name + "');</script>");

Answer №3

To address the problem of missing browsing history, you can utilize FireFox's FireBug extension to examine real-time source code.

This method offers a significant advantage compared to using a browser's 'Right Click > View Source' feature, as it may fetch the code directly from the server.
