Question

I use asp.net and c#.

I have a DetailsView and I need get the data bound to it.

I receive this error: Do you have an idea how to fix it?
Thanks for your time.

Please provide me a sample of code.

// Get the data for underlying DetailsView
DetailsView myDetailsView = ((DetailsView)sender);
WebProject.DataAccess.DatabaseModels.CmsContent rowView (WebProject.DataAccess.DatabaseModels.CmsContent)myDetailsView.DataItem;

Unable to cast object of type 'System.Web.UI.WebControls.EntityDataSourceWrapper' to type 'WebProject.DataAccess.DatabaseModels.CmsContent'.

To get object from DataItem you need to use approach described here: http://blogs.msdn.com/b/diego/archive/2008/05/13/entitydatasource-to-wrap-or-not-to-wrap.aspx
i.e. create class

static class EntityDataSourceExtensions
{
    public static TEntity GetItemObject<TEntity>(object dataItem) where TEntity : class
    {
        var entity = dataItem as TEntity;
        if (entity != null)
        {
            return entity;
        }
        var td = dataItem as ICustomTypeDescriptor;
        if (td != null)
        {
            return (TEntity)td.GetPropertyOwner(null);
        }
        return null;
    }
}

And then call

var row = EntityDataSourceExtensions.GetItemObject<WebProject.DataAccess.DatabaseModels.CmsContent>(myDetailsView.DataItem)
