Customizing ASP.Net MVC Template

Asp.net scaffold templates for controller and view are really useful but often we need to change the default template to fit with particular project. It's easy to do. Follow the steps below to customize the ASP.Net MVC3 built-in T4 template:

1. Go ahead and find the default template from the following location- 
[Visual Studio Installation Directory]\Common7\IDE\ItemTemplates\CSharp\Web\MVC 3 
2. Copy the "CodeTemplates" folder. 
3. Paste the "CodeTemplates" folder to the project's root. 
4. Remove the templates(extension '*.tt') that you do not need to customize from the project's "CodeTemplates" folder. 
5. Select the templates(press and hold ctrl and click on the template) and go to properties(right click and select properties). 
6. Clear "Custom Tool" entry. By doing this, it will not run the template automatically every time you build the project. 
7. Now customize the template as you want and build the project. 
8. Right click on View folder and select add view. From the add view popup dialog box, select the model class and you will find the customized template in the "scaffold template" drop down list.

Unable to evaluate expression because the code is optimized or a native frame is on top of the call stack

Suddenly I am getting the error "Unable to evaluate expression because the code is optimized or a native frame is on top of the call stack" from my asp.net application. After spending sometimes online, I found the following cause and solution for the error. Hope the solution might help you, if you are facing the same problem.

Error: Unable to evaluate expression because the code is optimized or a native frame is on top of the call stack

Cause: If you use either Response.Redirect or Server.Transfer method, you may face this problem. I was calling Response.Redirect method inside the Try...Catch block. This happens because both methods call Response.End internally.

Solution: Pass "false" to endResponse parameter of Response.Redirect method

Response.Redirect ("xyz.aspx", false);

Thats it. Simple.

Top Ten Reasons Behind the Popularity of Sharepoint

There are many reasons behind the popularity of Microsoft sharepoint server. All the details can be found in sharepoint official site . Also I have found some important discussion here too. However, according to my point of view, following are main 10 reasons behind the popularity of sharepoint server:

1. Very easy to use as collaboration platform as it needs browser to access the server
2. Instantly create sites from predefined template
3. Share documents and tracking them with role based security
4. Use as a easy project management tool( manage lists, todo, share files, etc)
5. Plug and play webparts
6. Integrate with microsoft most popular product microsoft office
7. Work from internet as well as intranet
8. Integrated task calendar with microsoft outlook. so accessible from outlook directly
9. Connect developer, manager and client in one platform
10. Document versioning and sharepoint designer support to open and edit sharepoint site

isn't it enough to be popular sharepoint :)

Sharepoint Installation

Sharepoint installation is very easy and straight forward. If anybody is interested then can follow the procedure below:

1. First of all download the WSS 3.0 from the following location- its good for beginner or you can buy MOOS2007(Microsoft Office Sharepoint Server 2007)

http://www.microsoft.com/downloads/details.aspx?FamilyId=D51730B5-48FC-4CA2-B454-8DC2CAF93951&displaylang=en

Maintain the following sequence in a windows 2003 server. If you don't have windows server 2003, you can try with virtual pc or vmware what I am doing now

2. Install IIS

3. Install .net framework 2.0/+

4. Configure server

5. Install WSS

At the final step of installation you will get the link of the server to access. Wish you will enjoy your time with sharepoint.

Make Understand IE6 About 'position:fixed'

Many times we need to use fixed position along with relative, static and absolute position in style sheet, specially in AJAX progress bar. Now question is what it does actually? To show the longer content of a web page, browser use scroll bar which can make your progress message out of the sight. Specially, while we update at the bottom of the ajax update panel, user might not notify about the waiting message or update message. We can easily fix the problem by using 'position: fixed' in CSS. But problem is IE6 or older version of IE, don't understand this. To make it understand on this particular style, we need to write a little javascript code in the CSS. Let see that simple code below:

.updateProgress

     {

       background-color:#CF4342;

       color:White;

       position: absolute; 

       top: expression(0+((e=document.documentElement.scrollTop)?e:document.body.scrollTop)+'px'); 

       right: expression(0+((e=document.documentElement.scrollLeft)?e:document.body.scrollLeft)+'px');}

     }

Now for cross browser support let see the full code below:

<style type="text/css"> 

        .updateProgress 

        { 

            background-color: #CF4342; 

            color: White; 

            top: 0px; 

            right: 0px; 

            position: fixed; 

        } 

        .updateProgress img 

        { 

            vertical-align: middle; 

            margin: 2px; 

        } 

    </style> 

    <!--[if gte IE 5.5]> 

    <![if lt IE 7]> 

    <style type="text/css"> 

    .updateProgress 

     { 

       background-color:#CF4342; 

       color:White; 

       position: absolute; 

       top: expression(0+((e=document.documentElement.scrollTop)?e:document.body.scrollTop)+'px'); 

       right: expression(0+((e=document.documentElement.scrollLeft)?e:document.body.scrollLeft)+'px');} 

     } 

    .updateProgress img { 

       vertical-align:middle; 

       margin:2px; 

     } 

    </style> 

    <![endif]> 

<![endif]-->

That’s all. Enjoy Programming!
