Question

enter code hereMy jquery ui dialog contains an iframe and has the option of two buttons, apply and close.
Here is my javascript generating this:

$(function () {
    $(".btn").click(function() {
        var $this = $(this);
        $('<iframe id="PDFDialog"  frameborder="0" src="' + this.href + '" />').dialog({
            title: ($this.attr('title')) ? $this.attr('title') : 'External Site',
            autoOpen: true,
            width: 700,
            height: 600,
            modal: true,
            resizable: true,
            buttons: {
                Apply: function () {
                    $("#<%= applyHiddenBtn%>").click();                        
                    $(this).dialog("close");
                },
                Close: function () {
                    $(this).dialog("close");
                }
            }
        }).width(650).height(550);
        return false;
    });
});

Im not sure how to execute my code behind that i have prepared for the dialog button “Apply”. As an attempt i have this other server button <asp:Button runat="server" ID="applyHiddenBtn" OnClick="applyHiddenBtn_Click"/> that i try firing at the same time.

The goal is to fire this:

Sub applyHiddenBtn_Click(sender As Object, e As EventArgs)
    lblTest1.Text = "HelloWorld!!!1!"
End Sub

Any help please?

Answer 1

The following will execute a POST to the server executing the handler for your applyHiddenBtn:

__doPostBack('applyHiddenBtn', '');
