Have you tried Model.Content.HasValue("gridAlias")?

Hi,

First you Need this: https://github.com/skybrud/Skybrud.Umbraco.GridData

than you can get the GridDataModel like this:

/*var json = entity.GetValue<string>("grid");
GridDataModel grid = GridDataModel.Deserialize(json);*/ 
GridDataModel grid = Model.Content.GetPropertyValue<GridDataModel>("bodyGrid");// thanks to Streety

With this function you get a boolean if the grid has data or not

using Skybrud.Umbraco.GridData;
using System.Linq;

namespace Web.Helpers
{
    public static class GridHelper
    {
        public static bool HasData(this GridDataModel grid)
        {
            bool hasData = false;
            if (grid == null)
            {
                hasData = false;
            }
            else
            {
                hasData = (from section in grid.Sections
                            where section.HasRows
                            from row in section.Rows
                            where row.HasAreas
                            from area in row.Areas
                            let hasGridData = area.HasControls
                            select hasGridData)
                            .Any(hasGridData => hasGridData == true);
            }
            return hasData;
        }
    }
}

Finally you can check for the grid if it is empty

if (grid.HasData() == false)
{
    //grid is empty
}

I hope this helps you :)

It has some basic JSON markup, so it's never empty. It never said the following ;) you could check for stringlength of the gridvalue, beneath 120 is empty.

OK so i got this to work but the above suggestion doesn't and its rather confused.

So the first bit, get the

https://github.com/skybrud/Skybrud.Umbraco.GridData

to get access to the gridmodel

Put a using statement to access the Model & your Gridhelper method

@using Skybrud.Umbraco.GridData et al

next paste in this block

@{GridDataModel json = Model.Content.GetPropertyValue<GridDataModel>("bodyGrid");

if (json.HasData())
{
          Do stuff if the grid has content
}

}

You actually don't want to deserialise at all.

Works for me.

Thanks for the Gridhelper Aaron Morf

GridDataModel doesn't seem to have a HasData()-method in the 1.5.1 release. How should it be checked? I really don't want to count characters :)

Hi,

Is there any solution to that problem that doesn't involve getting the https://github.com/skybrud/Skybrud.Umbraco.GridData ?

I have the same issue and don't want to download this package as it can mess things up for me, and specially that I'm still not clear on how to use it

Hi

We have an extension for checking is there a grid value:

public static bool HasGridValue(this IPublishedContent contentItem, string alias)
    {
        try
        {
            if (contentItem.HasValue(alias))
            {
                var stringValue = contentItem.GetPropertyValue<string>(alias);
                if (!string.IsNullOrWhiteSpace(stringValue))
                {
                    var grid = Json.Decode(stringValue);

                    if (grid.sections[0].rows.Length >= 1)
                    {
                        return true;
                    }
                }
            }

        }
        catch (Exception e)
        {
            CustomLogHelper.Error<UmbracoViewPage>(e.Message, e);
        }


        return false;
    }

Use it like:

if (contentItem.HasGridValue("body"))

Thanks,

Alex

quick and dirty with ModelsBuilder....

var dev = Model as DevelopmentPage; var hadGridContent = dev.GridContent["sections"][0]["rows"].Count() >= 1;

My 2 cents. Adding empty sections/rows should also count as an empty grid, so i check on any editors being present. You can get the value of the grid as a JToken en just query it that way

public static bool HasGridValue(this IPublishedContent content, string alias) 
{
    return content.Value<JToken>(alias)["sections"]?.Any(s => s["rows"]?.Any(r => r["areas"]?.Any(a => a["controls"].Any()) == true) == true) == true;
}

is working on a reply...
