  • ASP.NET State Error

    - by Sayem Ahmed
    I am have an asp.net page, where a list of products is shown in a drop down. When a user selects an item, corresponding price, available quantity etc. are shown in the corresponding text boxes. I have used ajax update panel to retrieve these information. This approach seems to work nicely. But sometimes when a product is selected, it takes too long for the price, quantities to change, and sometimes they don't even change. Then I used firebug to see what happened to the ajax request, and I found out that the response that is coming from the server is something like this - 70|error|500|The state information is invalid for this page and might be corrupted.| I have absolutely no idea what is wrong here.............

  • Accessing and binding events to an ASP.NET Grid view using Jquery

    - by Sayem Ahmed
    I have an ASP page which displays a text box when it loads. It takes an input number, send it to the server through post back, and then displays some record in a grid view. After a number is input into the box, the server fetches some data from a database and add records to the grid view. It also contains a link column, whose URL is set to "#", so that the page isn't redirected when it is clicked. Now I want to bind a jquery "click" event to that link. How can I do that ? I have tried that to do myself but failed, because it is not available when the DOM is loaded (since it only contains rows when a number is input through the box), and is being modified through ASP.NET Ajax post back.

  • Computer Quiz Management Software

    - by Asad Jibran Ahmed
    My university is holding a quiz contest in 2 weeks, and I need some sort of software (desktop or web based) that can be used to manage the quiz. I need functionality like an admin panel for adding teams, creating matches between 2 teams, adding questions and answers. I then need the software to automatically display the questions, accept answers, and display and store results. Is there any software (open source/freeware) that I can use for this task. If a pre-built software is not available, which language+library+platform would you suggest I make the software in. It can be either web based or a desktop app. But I need it by 2 weeks. Any suggestions?
