Hi friends, I want to pass the data to javascript function when click on the button. I write the code like this.

<asp:button id="Button1" runat="server" onmousedown="del(document.getElementById('TextBox1.Text'))" xmlns:asp="#unknown">
Text="Button" />

In java script function

function del(txt)
{
document.Write(txt);
}

But the answer came as NULL

Can anyone correct it?

<asp:button id="Button1" runat="server" onmousedown="del(document.getElementById('<%=TextBox1.ClientID%>'))">

The issue is that TextBox1, is not called TextBox1 on the client.

Ok. I solve it. Is it possible to pass session variable inside the function?

The session variable is on the server, you'd have to pass it to javascript by writing some script that defines a client side variable and sets it to the server side value. Don't forget to put it in quotes if it is a string.

var myClientsideString = '<=Session["key"]>';

inside a script block, obviously.

I want to check the session variable when the form is unload. I write the code like this.

function del()
{
alert(Session["nam"]);
}

But the unload event is not trigerring. Whats the fault in this code?

Erm, I think you have to pass the TextBox1's value, surely, and not the whole control?
I might be wrong, but that's what i gathered from the del(txt)function.

var question = (_2b || !(_2b));

Page blocker in ASP.NET 2.0 using C#

That would work, if the button he was clicking, was also the textbox he entered text into.

Hi folks,

I am developing the web site in asp.net 2.0 with c#. Suppose there is registration page and when some one clicks on the submit button then that page is block and system display the "please wait..page is loading" (image) before redirecting to the next page. Page block means that user will not be able to do anything else in between the process. I need the code for this.

Any help would be greatly appreciated.

Many Thanks

Kamlesh

I guess you need AJAX to do that.

thanks for your reply. but how can i achieve this using AJAX. any code?

Christian Graus26-Apr-09 22:08

It's not really an ASP.NET question anymore. And no, I don't have the code to do this on hand, b/c it's complex. Whatever process you want to do on the back end, is what you need to do in an AJAX call, or a series of calls, which will allow you to show a progress bar and/or redirect when it's done.

An AJAX Modal PopUp blocker would serve the purpose. Or else you can write your own javascript to set the page Opacity also...

Does the ASP.NET AJAX library work with ASP.NET 2.0 ?

I'm expecting the OP to get the AJAX extension library added, and do the necessary changes in the web.config and all the remaining stuff if in case he wants to use the AJAX control.

Am I expecting too much? Confused | :confused:

I wasn't sure if it worked in the 2.0 framework, that's all

But, nowadays, it's possible you would be expecting too much, in any case...
