I have simple UI in aspx file, with aspx.cs codebehind. No matter what kind of control I use, events from this file wont fire - the only ones that are working are events like Init, PageLoad.
Events are created via designer.
What I tried:
Basic OnClick on markup page
OnClick in designer
Inline c# Code in markup page via javascript
PageMethods
Pure javascript click
Whole new page
When I add for example alert for click event in javascript, it works. But Im not able to run my c# code after user clicks on button.
I have also removed everything from file (validation, other controls...), but not even then my code works.
There are also no errors in console

This code worked in another page
But it's not working in the new page
JS Function to be called:
<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="Server">
<script type="text/javascript">
function myfun() {
alert("test");
}
</script>

Html code:

Code behind:
protected void IMGDetail_Click(object sender, ImageClickEventArgs e) {
LinkButton lbtn = (LinkButton) sender;
GridViewRow gvr = (GridViewRow) lbtn.NamingContainer;
Label LabelTicketId = (gvr.FindControl("LBTicketId") as Label);
Session["TicketId"] = LabelTicketId.Text;
ScriptManager.RegisterStartupScript(this.Page, Page.GetType(), "text", "myfun()", true);
}
I think you need to add following tag in your aspx page.
<asp:ScriptManager ID="ScriptManager" runat="server" />
In Codebehind
ScriptManager.RegisterStartupScript(this, typeof(string), "myfun", "myfun()", true);
I am having problem with the script of passing values from child to parent with tabpanel (controller). Within that Tab there's a textbox. When I tried to pass a value that within the TabPanel it doesn't work. When I removed the panel it works.
Here the html script from
Parent.aspx

The scenario child must pass the value to textbox1 within that TabPanel. Hoping that someone will help me to resolve the problem.
Done, I resolved this problem.

Am I missing something?
I inserted the code above into empty aspx page, removed reference to masterpage and asp:Content and it worked for me. The label changed its text.
If it still doesn't work for you you may use Firefox+Firebug to see the actual server response after clicking on a button. It may contain detailed exception that will give you a hint.
I have 2 pages, Cart.aspx and SelectPartner.aspx. And a JavaScript file, popup.js
In Cart.aspx I have a button that opens the page SelectPartner.aspx (as a new window) by the InvokePop() function.
In SelectPartner.aspx I have a gridview (with Selection enabled), a textbox, and buttons Ok and Cancel. This is what I want to do: when I select an item in the gridview, the value of one column is shown in the textbox, and when when I press the button Ok the function ReturnPartner() is called and should close the this window (SelectPartner.aspx) and show the value of this textbox in another textbox in the Cart.aspx page. If I write something into the TextBox in SelectPartner.aspx I can pass that value to the TextBox in the Cart.aspx page, but when I press a select button in the gridview the value is not passed.
I don't know what happens, please help me...
Here is the code of Cart.aspx
<%# Page Title="" Language="C#" MasterPageFile="~/Site.Master" AutoEventWireup="true" CodeBehind="Cart.aspx.cs" Inherits="NMv01.Cart" %>

And this is the popup.js file:
function InvokePop(fname) {
val = document.getElementById(fname).value;
// to handle in IE 7.0
if (window.showModalDialog) {
retVal = window.showModalDialog("SelectPartner.aspx?Control1=" + fname, 'Choose Partner', "dialogHeight:360px,dialogWidth:360px,resizable:yes,center:yes,");
document.getElementById(fname).value = retVal;
}
// to handle in Firefox
else {
retVal = window.open("SelectPartner.aspx?Control1=" + fname, 'Choose Partner', 'height=360px,width=360px,resizable=yes,modal=yes');
retVal.focus();
}
}
function ReturnPartner() {
var returnString = document.getElementById('txtPartner').value;
RetrieveControl();
// to handle in IE 7.0
if (window.showModalDialog) {
window.returnValue = returnString;
window.close();
}
// to handle in Firefox
else {
if ((window.opener != null) && (!window.opener.closed)) {
// Access the control.
window.opener.document.getElementById(ctr[1]).value = returnString;
}
window.close();
}
}
function RetrieveControl() {
//Retrieve the query string
queryStr = window.location.search.substring(1);
//Retrieve the control passed via querystring
ctr = queryStr.split("=");
}
I would suggest you to remove the use of window.showModalDialog() and use window.open() instead because Window.open() is supported uniformly by all browsers while window.ShowModalDialog() is an MSIE feature only.
showModalDialog() is said to have trouble "posting back" for which a iframe hack is needed.
i tested your code with window.open for all browsers and it worked great.

Firebug throws the following error:
__doPostBack is not defined
[Break On This Error] "OK": function () { __doPostBa...ID, ''); $(this).dialog("close"); },
If anyone could provide a solution with the above, it would be greatly appreciated.
I have spent days looking at different jQuery confirmation box examples but this is the best I can do. Ideally I would want to be use http://jqueryui.com/demos/dialog/#modal-confirmation within gridviews, dataViews and ListViews but can't find examples which exactly provide steps to follow.
Thanks
Or you could use this:
protected void Page_PreRender(object sender, EventArgs e)
{
//If the page doesn't have a control that causes a postback, __doPostBack() won't be output
//as a function definition. One way to override this is to include this line in your Page_PreRender():
Page.ClientScript.GetPostBackEventReference(this, string.Empty);
//This function returns a string calling __doPostBack(); but also forces the page to output
//the __doPostBack() function definition.
}
