Problem using \citep{} w/ biblatex and @online

Question

Got the following
Document:

\documentclass[a4wide,11pt]{report}

\usepackage[dutch,english]{babel}
\usepackage{blindtext}
\usepackage{biblatex}

\usepackage{hyperref}

\bibliography{Bibliografie_AG.bib}

\begin{document}

Something blablabla \citep{MendeleySearch}

\printbibliography
\end{document}

Bibliografie_AG.bib (e.g.):

@online{MendeleySearch,
 author               = {John Doe},
 month                = {5},
 title                = {Mendeley | Search},
 url                  = {http://www.mendeley.com/research-papers/},
 year                 = {2012},
 }

I'm using biblatex to reference URLs. But now I cannot use /citep or something listed here.

Is there any way to make this happen?

Answer 1

The following, simplified form of your MWE works fine if one remembers to run bibtex after the first LaTeX pass, and then run LaTeX twice more:

\documentclass[11pt]{report}

\usepackage[citestyle=authoryear,natbib=true,backend=bibtex]{biblatex}
\renewcommand\nameyeardelim{, }

\bibliography{Bibliografie_AG.bib}

\begin{document}

Something blablabla \citep{MendeleySearch}, \ldots

As shown by \citet{MendeleySearch}, \ldots

\autocite{MendeleySearch} % same output as \citep

\printbibliography
\end{document}

Answer 2

As mentioned in the comments, \citep is not a biblatex command. It is a natbib command. You can get biblatex to work with \citep by using the option natbib=true. However, you could also try biblatex's own command: \parencite.

For author year citations, you should also use one of the author year bibliography style options:

\usepackage[natbib=true, style=authoryear]{biblatex}

See section 3.3 of the biblatex manual for a list of styles. These include: authoryear, authoryear-comp, authoryear-ibid and authoryear-icomp.
