Hi James,

Here's some razor I've used to do paging - you should be able to pick something from it:

@{
    var pageSize = 5;
    if(Model.Content.HasValue("numberOfItemsPerPage")){
        pageSize = Model.Content.GetPropertyValue<int>("numberOfItemsPerPage");
    }
    var page = 1; int.TryParse(Request.QueryString["page"], out page);
    var items = Umbraco.TypedContent(Model.Content.Id).Children.Where(x => x.DocumentTypeAlias == "Article" && x.IsVisible());
    var totalPages = (int)Math.Ceiling((double)items.Count() / (double)pageSize);

    if (page > totalPages)
    {
        page = totalPages;
    }
    else if (page < 1)
    {
        page = 1;
    }


    foreach(var item in items.Skip((page - 1) * pageSize).Take(pageSize).OrderBy(x=>x.Name)){
        <div>
            <h2><a href="@item.Url">@item.Name</a></h2>
            <p>@item.GetPropertyValue("introText")</p>
        </div>
    }


    if (totalPages > 1)
    {
        <div class="pagination">
            <ul>
                @if (page > 1)
                {
                    <li><a href="?page=@(page-1)">Prev</a></li>
                }
                @for (int p = 1; p < totalPages + 1; p++)
                {
                    <li class="@(p == page ? "active" : string.Empty)">
                        <a href="?page=@p">@p</a>
                    </li>
                }
                @if (page < totalPages)
                {
                    <li><a href="?page=@(page+1)">Next</a></li>
                }
            </ul>
        </div>
    }
}

It would be something like this:

foreach(var item in items.Skip((page - 1) * pageSize).Take(pageSize).OrderBy(x=>x.Name)){
    <div>
        <h2><a href="@item.Url">@item.Name</a></h2>
        <p>@item.GetPropertyValue("introText")</p>
        <img src="Umbraco.Media(item.MyMediaPickerAlias).Url" alt="" >
    </div>
}

Pretty close! This should work:

@Umbraco.Truncate(item.GetPropertyValue("introText"), 150)

@{ var pageSize = 5; if(Model.Content.HasValue("numberOfItemsPerPage")){ pageSize = Model.Content.GetPropertyValue

if (page > totalPages)
{
    page = totalPages;
}
else if (page < 1)
{
    page = 1;
}


foreach(var item in items.Skip((page - 1) * pageSize).Take(pageSize).OrderBy(x=>x.Name)){
    <div>
        <h2><a href="@item.Url">@item.Name</a></h2>
        <p>@Umbraco.Truncate(item.GetPropertyValue("introText"), 150)</p>
    </div>
}


if (totalPages > 1)
{
    <div class="pagination">
        <ul>
            @if (page > 1)
            {
                <li><a href="?page=@(page-1)">Prev</a></li>
            }
            @for (int p = 1; p < totalPages + 1; p++)
            {
                <li class="@(p == page ? "active" : string.Empty)">
                    <a href="?page=@p">@p</a>
                </li>
            }
            @if (page < totalPages)
            {
                <li><a href="?page=@(page+1)">Next</a></li>
            }
        </ul>
    </div>
}

}

hmmmm it not working ...got the error....it show this... Compiler Error Message: CS1502: The best overloaded method match for 'Umbraco.Web.UmbracoHelper.Truncate(System.Web.IHtmlString, int)' has some invalid arguments error i guess is about this @Umbraco.Truncate(item.GetPropertyValue("introText"), 150)

What do you get if you just output item.GetPropertyValue("introText").GetType()?

As you can see in your error, Umbraco.Truncate only accepts a string.

You could also try:

@Umbraco.Truncate(item.GetPropertyValue("introText").ToString(), 150)

Hello, I'm new with Umbraco and I'm working with my first website, I'm trying to implement the feature of pagination following the code displayed in this post. I'm using LeBlender for my grid editors, but I'm getting this error:

c:...\umbraco\Views\Partials\Work.cshtml(5): error CS1061: 'Lecoati.LeBlender.Extension.Models.LeBlenderModel' does not contain a definition for 'Content' and no extension method 'Content' accepting a first argument of type 'Lecoati.LeBlender.Extension.Models.LeBlenderModel' could be found (are you missing a using directive or an assembly reference?)

And here is my code:

@inherits UmbracoViewPage<Lecoati.LeBlender.Extension.Models.LeBlenderModel    @{
var pageSize = 6;
if(Model.Content.HasValue("numberOfItemsPerPage")){
    pageSize = Model.Content.GetPropertyValue<int>("numberOfItemsPerPage");
}
var page = 1; int.TryParse(Request.QueryString["page"], out page);
var items = Model.Items;
var totalPages = (int)Math.Ceiling((double)items.Count() / (double)pageSize);

if (page > totalPages)
{
    page = totalPages;
}
else if (page < 1)
{
    page = 1;
}


foreach(var item in items.Skip((page - 1) * pageSize).Take(pageSize).OrderBy(x=>x.Name)){

     <h2><a href="#">Olaaaaaaaa</a></h2>    
}


if (totalPages > 1)
{
    <div class="pagination">
        <ul>
            @if (page > 1)
            {
                <li><a href="?page=@(page-1)">Prev</a></li>
            }
            @for (int p = 1; p < totalPages + 1; p++)
            {
                <li class="@(p == page ? "active" : string.Empty)">
                    <a href="?page=@p">@p</a>
                </li>
            }
            @if (page < totalPages)
            {
                <li><a href="?page=@(page+1)">Next</a></li>
            }
        </ul>
    </div>
}

}

Would really appreciate some help on this.

Thank you very much!
