Question

I am working with MVC 3, Razor and Entity Framework. I am making a blog using MVC 3, so on the blog there are many posts. On the homepage I am showing for now say 10 posts.

I am using the following code to display posts.

 <h1 class="postTitle">@Html.ActionLink(post.PostTitle, "SinglePost", "Post", new { postID = post.PostID}, null)</h1>

 <div class="postDateTime"><b>Posted on :</b> @post.PostDateTime</div>
 <br/>
 @if(post.PostContent.Length > 500)
 {
     <span>@post.PostContent.Substring(0, 500) [Read More...]</span>
 }
 else
 {
     <span>@post.PostContent</span>
 }

 <hr class="postSeparator"/>
 </div>

I am a little confused as to how to implement paging for this, or better something like this implemented at SO.
Please guide me on this fellas.

Answer 1

The key point is to use Skip() and Take() LINQ methods when querying your model:

EG

int page;
int pageSize;
var postsToDisplay =db.Posts.Where(x => x.Tag == "EF")
                            .Skip((page -1) * pageSize)
                            .Take(pageSize);

You should place this in a ViewModel, and then use View which is strongly typed to your ViewModel.
