how JQuery UI Dialog & Asp (web forms) calling event handler

 

Questions


I have a form with a submit button. On clicking the submit button, i display a jqueryUI dialog with Confirm and Cancel. On clicking Confirm, I want to post back and call the submit button’s event handler not the Page_Load event.

I have the following

HTML

<input type="submit" value="Submit" id="submit" runat="server"  onclick="submit" />

JQuery

$("#dialog").dialog('option', 'buttons', {
                "Confirm": function () {
                    $("#ctl01").submit();
                },
                "Cancel": function () {
                    $(this).dialog("close");
                }
            });

so far, this will call the page_load event because i am ‘just’ submitting the whole form.

Server side

protected void Page_Load(object sender, EventArgs e)
    {
        if(Page.IsPostBack)
            result.Text += "hey post-back, we did it!";
    }

    protected void submit(object sender, EventArgs e)
    {
        result.Text += "hey, event handler! ";
    }

Answer

From your post I got that you want to simple go to the server side event while clicking on the button in the Dialog.
So I created a Hidden ASP Server Button and triggering it’s click from the Confirm button.

Here is the working code.

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
    <link href="CSS/ui-lightness/jquery-ui-1.8.16.custom.css" rel="stylesheet" type="text/css" />

    <script src="JS/jquery-1.6.2.min.js" type="text/javascript"></script>

    <script src="JS/jquery-ui-1.8.16.custom.min.js" type="text/javascript"></script>

</head>
<body>
    <form id="form1" runat="server">
    <div id="dialog" style="display: none" title="Empty the recycle bin?">
        <p>
            <span class="ui-icon ui-icon-alert" style="float: left; margin: 0 7px 20px 0;"></span>
            These items will be permanently deleted and cannot be recovered. Are you sure?</p>
    </div>

    <script>
        jQuery(function() {
            var dlg = jQuery("#dialog").dialog({
                draggable: true,
                resizable: true,
                show: 'Transfer',
                hide: 'Transfer',
                width: 320,
                autoOpen: false,
                minHeight: 10,
                minwidth: 10,
                buttons: {
                    "Confirm": function() {
                        $("#<%=btnNew.ClientID %>").click();
                    },
                    "Cancel": function() {
                        $(this).dialog("close");
                    }
                }
            });
            dlg.parent().appendTo(jQuery("form:first"));
        });

        jQuery(document).ready(function() {
            jQuery("#submit").click(function(e) {
                jQuery('#dialog').dialog('open');
            });

        })

    </script>

    <input type="button" value="Submit" id="submit" />
    <asp:Button runat="server" Style="display: none" ID="btnNew" Text="Submit" OnClick="btnNew_Click" />
    </form>
</body>
</html>

In _Default.asp.cs

public partial class _Default : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {


        }

        protected void btnNew_Click(object sender, EventArgs e)
        {
            result.Text += "hey, event handler! ";
        }


    }
