Hi,
Me too had similar problem. Try using following code
private void ShowMessage(string message)
{
//This code works if there's no UpdatePanel
//string script = "<script type=\"text/javascript\">alert('" + message + "');</script>";
//Page.ClientScript.RegisterStartupScript(this.GetType(), new Guid().ToString(), script);
//Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler);
// We must do something slightly different with an UpdatePanel
string jScript = "alert('" + message + "');";
ScriptManager.RegisterClientScriptBlock(UpdatePanelNewsLetter, UpdatePanelNewsLetter.GetType(), new Guid().ToString(), jScript, true);
}
now call the ShowMessage() function wherever required in UpdatePanel
Regards...

i have created a multiview which has 4 views.........multiview is placed in a panel.... when the active view is changed.... active views are displayed at different locations of the screen exactly whre they are present in ASPX file.......... i want that whatever view is active it should be displayed on the same location.....
What should i do

|

If you're using the asp.net multiview control it should be working fine, no need for extra panels.

in my .cs file when i write
droplist.Attributes.Add("onclick", "return confirm('Do you wAnt to continue')");
the above is working but when i write
droplist.Attributes.Add("onclick", "click()");
it doesnot what shud i do to solve the problem
i have a function in cs file
public void click()
{
}
|
|
|
|
|
droplist.Attributes.Add("onclick", "click()");
This line of code establishes that a javascript function named 'click()' will handle the javascript onclick event for your dropdownlist control.
i have a function in cs file
public void click()
{
}
You are confusing client-side event handlers (typically written in Javascript, located in the ASPX page) with server-side event handlers (written in your preferred .NET language, located in the code-behind file). There's no server-side onclick event for the DropDownList control, so presumably you want to define a javascript method to execute in the client's browser. You can do this thus:
<script language="javascript">
function click()
{
// add implementation here
}
</script>

Hello everyone,
I was wondering how Google Analytic works. The tool allows website owners to check where their visitor have been prior to coming to their website. If you know how such a tool works and what is required please elaborate. Thank you in advance for your time

severvariables and I believe the one you want is REFERER

Hi MrPlankton,
Thank you so much for responding to my post. I have Googled ServerVariables Referer, Referer, and Server Variables but nothing useful came up. A bunch of the sites that came up were in Chinese. On one of the sites that came up, it said Server Variables are used on Cold Fusion server. I don't know anything about Cold Fusion server at this point. Do you know where I can more info on Server Variables and how to use them? Thank you in advance for your help.

let's say I have a page page.aspx, it includes a class named SampleClass and a method name myMethod.
I want to call this method from a HTML page.
how do I do this?

There are 2 ways of doing this in my experience;
1. Set a flag, say a hidden text field with some indicator of what method you want to call on the server. Then do a self submit in javascript and look for flag on Page_load event. If you see the flag call the method.
2. Use ajax
MrPlankton

I don't know to perform both of your suggestions

I have an article which is basically a control for implementing ajax (which is what your talking about). These days though you should just look into asp.net ajax. www.asp.net
|
|
|
|
|
If it's asp.net (page.aspx would indicate this) you just need an event, say a button click to generate the postback, from which you can call the method you want.
Or, script callbacks, http://www.developer.com/net/asp/article.php/3485991[^]

could you explain to me how to this please?
I mean, what I'm trying to do is to use a method \ function from VB\C#.NET compiled class in the App_Code folder from a simple html page at the OnClick etc. event that has been raised via a HTML and other pure client controls\events.

Hello all,
I am quite in a dilemma at the moment since i cannot find some independent reading which thoroughly describes the characteristics of j2ee vs .net.
I am experienced with .net but would like to know what the j2ee platform offers since several components used are totally free.
can anybody give me his/her views on the subject.
Thank you very much,
Chris

This forum is for programming questions specifically related to ASP.NET.
I suggest you post your question in the 'General Discussions' forum.

I'm working on an application which has a viewstate of approximately 250kb in a Notepad file. When doing a postback (e.g. on changing a dropdownlist's value) it takes a whopping 9 seconds to reload the page. This isn't really workable, problem is that I can't rebuild the application (as much as I'd like to) and I cannot disable the viewstate. Is there any way to speed this entire process off, or anything else that might be causing this besides the viewstate?

Rather than having the drop down list AutoPostBack, have you thought of using AJAX or JavaScript to handle the onchange event? Would be a lot quicker and provied a better user experience all round.
Clean code is the key to happiness.
