This is very important and small tips for all VS users. Sometimes we need a small piece of code in many places of our application or in some different application. What we do? We just copy the code from one page and paste it to the destination page.

Visual Studio having a great feature, that you can place your code snippet inside the toolbox. For that you need to just select the code snippet and drag the selected snippet on to the general Tab.CodeSnippet

You can rename the selected snippet, by just right clicking on snippet and click on Rename.

RenameCodeSnippet

Now, you can use it anywhere in your application or in any VS Application by just drag and drop of the selected snippet.

Hope this will help you in future from rewrite of code.

How to Freeze GridView Header While Scrolling ?
This is very common problem in Web development that we need to freeze the GridView header at the time of scrolling, Here is one simple tips:
Step 1 : Create a CSS class as following

.HeaderFreez
{
position:relative ;
top:expression(this.offsetParent.scrollTop);
z-index: 10;
}

Step 2 Set Gridview’s HeaderStyle CssClass as follows
CssClass="HeaderFreez"
That’s all. Some times we need also maintain the scroll positions while selecting any data from GridView, and quite difficult to maintain the position while we are using AJAX, I have written a complete article on that, hope this will help Maintain GridView Scroll Position inside updatepanel

    I have tried (and still trying hard) so many times to configure IIS on windows server 2003 standard edition. It seems not to be working despite reference to tens of articles, how-tos and walkthroughs. Can you please give me SURE guides on how to configure IIS on Windows server 2003. I really want to run my ASP.Net website on my Local Network first before hosting them on website. I already have compiled ASP.Net projects I want to setup.

    Thanks for your help

      • I have read this before; but couldn’t get it to work. But I will go through it again; and keep you posted on the progress. Thank you so much for being of help

      • I got this error when i try to browse my website from the IIS Manager:

        The page cannot be displayed
        You have attempted to execute a CGI, ISAPI, or other executable program from a directory that does not allow programs to be executed.
        ——————————————————————————–

        Please try the following:

        Contact the Web site administrator if you believe this directory should allow execute access.
        HTTP Error 403.1 – Forbidden: Execute access is denied.
        Internet Information Services (IIS)

        ——————————————————————————–

      • In Virtual Directory property window, you have a dropdown box “Execute permission”, what is the value of that ?

        And you can register iis using asp.net using aspnet_regiis command.

        Thanks

  25. I just noticed you used php on this website when i submitted this comment. Why? despite your wealth of asp.net knowledge. Is it that php is better than aspx in certain instances?. Kindly enlighten me.

  26. Thank you for the real instant response

    1. “Execute permission”= None. But when i change this to either of the 2 0ther options; i get the message that ‘The Web Application is not available’

    2. On which directory in the command prompt am i to use the ‘aspnet_regiis’ command.

    • Hi,

      Check the security Tab of your Folder and check what permission do you have.
      “Execute permission” should be chnaged script and executable.

      For Ruuning aspnet_regiis form the the Framework Directory. Ideally it should like C:\Windows\Framework\Version\V 2. XXXX\ aspnet_regiis.exe

      Goto Command prompt > navigate to that folder > Run > aspnet_regiis – i

      After that, Goto IIS > Right Click on Virtual Dir > Goto ASP.NET Tab > Set the proper version
      Let me know if it not resolved.

      • Thank you for for your help, i was able to successfully register aspnet with my iis using the instruction you provided.

        Also i changed the execute permission property to ‘Script and Executable’
        i also changed the version of ASP.Net to 2.0.50727

        But when i browse the site from iis manager, i got the following error message:

        Server Application Unavailable
        The web application you are attempting to access on this web server is currently unavailable. Please hit the “Refresh” button in your web browser to retry your request.

        Administrator Note: An error message detailing the cause of this specific request failure can be found in the application event log of the web server. Please review this log entry to discover what caused this error to occur.

        What do i do to resolve this? Thanks

      • Did you create the aplication form : Right Click Virtual Directory > Goto Virtual Directory Tab > Goto Application Setting Section > Click on Create Button.

        You also need to give aspnet user access to that virtual directory.

        Then Reset your IIS.

        You are ready to go..

        Let me know if you need any more help.

  27. Thank you. The error ‘Server Application Unavailable’ is still there even after i did all you said i should do except ‘give aspnet user access to that virtual directory’

    So, how do i ‘give aspnet user access to that virtual directory’

    • Hi, Sorry for late response. There should not be any error. I would suggest you to delete the virtual directory once and create fresh one. Set all the properties properly. Hope this will resolve your issue.

      And regarding how to give user access, I would recomand you to go through my IIS article.

      Thanks !

  45. Hi Sir,
    Well done for your contribution to the society in .NET platform.
    Actually I have one problem. I am kinect using Kinect SDK beta 1.0 SDK. I have one MainWindow.xaml and its code file. I want to open serial port only a single time but when I put it in Mainwindow.xaml.cs file I found that (using debugger ) code is executed several times as image is regenerating continously as I am showing image of the camera of Kinect. So where should I put sp.Open() where sp is Serial Port object so that it will be executed only once in the program i.e. at the beginning of the program.

    Thanks in Advance.

  46. Hi ahhi,

    Continue your good job and many thanks for share your valuable knowledge.
