How to do ASP.NET MVC Pagination in 30 minutes?

August 2, 2011 1 Comment

I needed web content pagination in my ASP.NET MVC 3 project. I found few solutions on the web, but end up accessing the first two below.

Telerik
Telerik has ASP.NET MVC extensions which I think is free and cool. To get the Telerik paging working in my MVC application I install Telerik MVC Extension nuget using Visual Studio 2010 NuGet Package Manager. Then I configured the controller, view and off you go. I got something like this.

MvcPaging
MVCPaging is also another easy way to achieve paging. Install MvcPaging nugget using Visual Studio 2010 NuGet Package Manager. Download the source code for MvdPaging form github and see the sample in MvcPaging.Demo. I also found this article useful to understand MvcPaging.

MvcContrib
I did not end up accessing MvcContrib, because MvcPaging fit my requirements. Here is a nice article with source code if you are interested.

I end up using MvcPaging for my application as I needed to be able to display boxes of information and paging on the bottom of the webpage as shown in the MvcPaging image above. But if you have lot of data and need to show it in a grid Telerik is a great option too.

Please let me know if you find any other better solutions for paging.

Keep you MVC Razor view DRY!

July 22, 2011 Leave a Comment

Always keep your view DRY (do not repeat). Suppose your website has any of the following,

  • Top menu
  • Left menu
  • Right menu

Or you have some HTML which is repeated in different view, then you could use the following,

@Html.Partial(“ViewFile”)
Renders the “ViewFile” view to an MvcHtmlString. It follows the standard rules for view lookup (i.e. check current directory, then check the Shared directory).

@Html.RenderPartial(“ViewFile”)
Does the same as Html.Partial(), except that it writes its output directly to the response stream. This is more efficient, because the view content is not buffered in memory. However, because the method does not return any output, @Html.RenderPartial(“MyView”) won’t work. You have to wrap the call in a code block instead: @{Html.RenderPartial(“ViewFile”);}.

@RenderPage(“ViewFile.cshtml”)
Renders the specified view (identified by path and file name rather than by view name) directly to the response stream, like Html.RenderPartial(). However, it seems to always use the current view’s model as the model for “ViewFile.cshtml”.

I prefer using @RenderPage(“ViewFile.cshtml”) only because the syntax is easier and it is more readable. If you are using MVC Area RenderPage by default will look into the View and Shared folder of the Area. If you want to point it to the common View folder in the root, then you have to mention the path. See example below.

@RenderPage(“~/Views/Shared/ViewFile.cshtml”)

More security steps to secure your Facebook profile

December 30, 2010 Leave a Comment

I thought I have secured my Facebook profile by doing the following steps, but I was wrong.

1. Change “Privacy Settings“.
2. Turn on “Account Security”.

As mention above, I have lock down my “Privacy Settings” to friends only list and changed “Account Security”. I think this is not enough.

Some times you add people to your Facebook because you met them once, got a Facebook friend invitation from them and you do not want to be rude by not accepting them. You are also not comfortable sharing your family photo album or wall messages with them. What do you do?

Your ‘Once met and do not trust’ friends in Facebook can also share your photo albums in their wall, which will give access to all their friends. You may not know your friend’s friend or you may not want to share your family album. What do you do?

In short, create a new list under friends, add only people you trust, go to various “Privacy Settings” and give access to only the new list you created.

See the detail steps below,
1. Login to Facebook.
2. Go to Account/Edit Friends and click on the “Create List” button.
3. Add all the people you trust in that list.
4. Go to Privacy Setting/Customize Settings. Click on drop down box and select ‘custom’.
5. “Custom Privacy” dialogue box will appear. Under ‘These people’ drop down box select ‘Specific People’.
6. In the text box below type the name of the new custom trusted friend list you created.
7. Start step 4 again for different privacy settings e.g. Album, website, applications, bock list etc.

Now, if you boss send you a Facebook friend request you can accept without hesitation and not add him/her to your custom friend list. Your boss will only see things which the default Facebook friend list has access to.
