Replacing ASP.NET POSTBACK with jQuery form posting -

-

I have a login screen, I have 2 text boxes and 2 radio buttons. I also have an ASP.Net button. The user clicks the button in his code, also clicks from the button, I have the following lines to check the user login 

  string emailId = txtEmailId.Text.Trim (); String password = txtPassword.Text.Trim (); // The code is valid for user checking ... if (isValid) {Response.Redirect ("index.aspx"); } Else {lblMSg.Text = "InValid Login"; }

This is the typical ASP.NET process. Now I want to avoid the posting of the page and I must use the jQuery form to post. Anyone can guide me how to do this? Hey, I can read the asp.net control value as "= txtEmailId.Text". Can I do this in the jQuery form posting method? I know that I am passing an email and password as an email string. Now I do not want to use the query string to do this. Any ideas ?? Use

Thanks in advance

$ Post to post back

Reveal your method as a service method so you can call it "pagename.aspx / methodname"

Call in format.

-
Using Visual Studio 2005, if I open the test in VSMFI and try to run the tests, then sometimes the projects are ready. However, they run very slow. CPU 99% waste and output window VS Shows things associated with compiling it. Is there any way to fix this? It does not make any sense. It is not necessary to upgrade that we are a viable alternative to those people who have to deal with the legacy code. Did you try to upgrade SP1? I do not know of any specific problem in this area, but this will be the first change I tried to do.

I am trying to install Ubuntu on a USB, the problem is that I do not want to repeat the boot once, I want to keep my windows, but I want to boot Ubuntu using the virtualbox and USB to the Ubuntu Want to use my hard drive, but how? The virtualbox will not recognize USB as a hard drive when installing an ISO In virtualbox, you have to create a virtual hard disk. Make a USB drive and tell the virtual box to install a virtual hard drive that you just created. EDIT: To answer some more questions: In the new Virtual Disk dialog, click the button next to the location field, click on the button Virtual Disk on Flash Drive To access, click the arrow next to Save in the Select File in the window next to Save In, and you can access your flash drive from there. I recommend setting the image to be allocated dynamically, because the size of your flash drive is not available disk space.
