Stopping Automatic Downloads

I have most apps set to update automatically as it's very convenient. I shall soon be going to parts of Europe that are outside the EU and where data download is horrendously expensive.

I shall mainly use wi-fi when it's available but I may occasionally need to access the web for a short time. My worry is that if I turn on data transmission it will start updating apps and cost me a small fortune in download charges.

Is there any way of doing a batch alteration, where I can switch off auto updating for all my apps, or must I go through them one by one?

If I have to do them individually how is this possible? I can find no way of turning off auto updates in an application and looking at my apps in Google Play appears to offer no such choice.

Thanks.

I've answered my own question. I assumed that Google Play, accessed on my PC would give me some control over this, but found nothing.

I have since accessed Google Play on my phone and found an option to only update when using wi-fi, which should solve my problem!
