    Can't Reference Individual Values - Razor Newbie

    Hi, I'm having trouble with pulling the individual values from the data grid. I can get the full string with both label and value, but i'm new to razor and having trouble.

    @widget.featureBlock gives me everything within the datatype.

    [ { "blockTitle": "Feature Block 1", "blockParagraph": "Feature Block 1 Content", "blockIcon": "1094", "urlPicker": "1062" }, { "blockTitle": "Feature Block 2", "blockParagraph": "feature Block 2 Content", "blockIcon": "1095", "urlPicker": "1054" } ]

    My razor macro is

    @{
    var widgetsFolder = Model.WidgetsFolders.Where("Visible").First();
}

@foreach (dynamic widget in widgetsFolder.Children.Where("Visible and nodeTypeAlias.StartsWith(\"Widget_\")")) {

    string widgetType = widget.NodeTypeAlias.ToString();

    switch (widgetType) {
        case "Widget_FeatureBlocksReveal":
        @showFeatureBlocksReveal(widget);
        break;
        default:
            <b>Unknown Widget!</b>
            break;
    }

}

@helper showFeatureBlocksReveal(dynamic widget){


    if (!string.IsNullOrEmpty(widget.featureBlock.ToString()))
    {
        foreach(dynamic content in widget.featureBlock)
        {
            @content.blockTitle
        }
    }   
}

    Any help would be grateful.

    Hi Martin.

    Which version of umbraco do you use?

    Your helper looks fine..

    Try to use the example from the project page:

     

    @helper showFeatureBlocksReveal(dynamic widget){
            if(!string.IsNullOrEmpty(widget.featureBlock.ToString()))
            {
                foreach(var content in widget.featureBlock)
                {
                <p>    @content.blockTitle</p>
                }
            }   
    }

    Hi Gilad, thanks for your help.

    I tried to use the example razor from package page, but using CurrentPage didnt validate inside the macro and gave the following error.

    "error CS0103: The name 'CurrentPage' does not exist in the current context"

    @helper showFeatureBlocksReveal(dynamic widget){
    if(!string.IsNullOrEmpty(widget.featureBlock.ToString()))
    {
        foreach (var content in CurrentPage.widget.featureBlock)
        {
            <p>@content.blockTitle</p>
        }
    }   
}

    Using the following helper, I am given an error of

    "Error loading MacroEngine script (file: RenderWidget.cshtml)"

    @helper showFeatureBlocksReveal(dynamic widget){
    if(!string.IsNullOrEmpty(widget.featureBlock.ToString()))
    {
        foreach (var content in widget.featureBlock)
        {
            <p>@content.blockTitle</p>
        }
    }   
}

    When I remove the .blockTitle and leave just @content, the macro works, but outputs all the values of the grid data type.

    Again, any help would be appreciated. Martin

    Edit: Sorry im on the latest version of Umbraco installed through nuget
