I can display an image with the code in a partial macro as follows:

@inherits Umbraco.Web.Macros.PartialViewMacroPage

@{
    var vkindEventsParentPageId = Model.MacroParameters["kindEventsParentPage"];
    //var vkindEventsFilter = Model.MacroParameters["kindEventsFilter"];


    var vHomeNode = Model.Content.AncestorOrSelf(2);
    var vParentPageNode = vHomeNode;
    vParentPageNode = Umbraco.Content(vkindEventsParentPageId);

    int vCtr = 0;
    foreach (var vEventItem in vParentPageNode.Children)
    {
        if (vCtr == 0)
        {
            @:<div class="row clearfix">
        }
        <div class="col-md-4 column">
            <div class="panel panel-default">
                @{
        if (vEventItem.HasValue("logo", true))
        {
            var mediaItem = Umbraco.TypedMedia(vEventItem.GetPropertyValue("logo", true));
            <div class="panel-heading">
                <div class="panel-title">
                    <div style="float:left; width:25%">
                        <img src="@mediaItem.GetPropertyValue("umbracoFile")" alt="@mediaItem.GetPropertyValue("Name")" />
                    </div>

This works fine. But if I use similar code in a Partial View "Umbraco.TypedMedia is not available:

@model UmbracoWebsites.Models.kindEvents

@using System;
@using System.Data;

@{
    int vCtr = 0;
    foreach (DataRowView vRow in Model.kindEventsView)
    {
        dynamic vEventNode = vRow["EventNode"];
        if (vCtr == 0)
        {
            @:<div class="row clearfix">


        }
        <div class="col-md-4 column">
            <div class="panel panel-default">
                @{
        if (vEventNode.HasValue("logo", true))
        {
            var mediaItem = Umbraco.TypedMedia(vEventNode.GetPropertyValue("logo", true));
            <div class="panel-heading">
                <div class="panel-title">
                    <div style="float:left; width:25%">
                        <img src="@mediaItem.GetPropertyValue("umbracoFile")" alt="@mediaItem.GetPropertyValue("Name")" />
                    </div>

What am I doing wrong?

Your help would be much appreciated.

Thanking you in anticipation.
