Problems when adding custom viewstyle to vwstyles.xsl and vwstyles.xml

Question

I've been trying for quite a few hours to customize the thumbnail view on a picture library in SharePoint 2013 without luck.

What I want to do is add the date the picture was taken underneath the title of the image. So that it displays both when the thumbnail view is collapsed, and when it's moused over.

I've tried to google this alot, and tried both jQuery solutions and editing the vwstyles.xml and vwstyles.xsl files. Doing iisreset everytime I edit something, but without any luck.

It feels like the class names and id's in the xml and xsl files aren't present in the actual page, and the other way around.

So I was wondering if anyone in here had done the same earlier, because I'm running out of ideas on where to edit these files to make the changes appear on the page.

I made a new ViewStyle in the xml file (copied from the "ViewStylePicLibDetailsName" style) and copied the same ID in the xsl file and gave both new ID's and a new name for my ViewStyle. That seems to work well, but none of the changes I make appear on the page.

Here's the ViewStyle in my vwstyles.xml file:

<ViewStyle ID="21" DisplayName="CustomThumbnail" BaseType="1" Type="109" Preview="_layouts/15/images/prvpicl.gif" Description="$Resources:core,ViewStylePicLibDetailsDesc;">

And here's the parts of the xsl file I've tried to edit, I've added some

tags to see if they appear in the table on the page, but they never do.

<xsl:template match="View[ViewStyle/@ID='21']" mode="RenderView">

Solution

From personal experience: Editting .xsl (like vwstyles.xsl or fldtypes.xsl) files of SharePoint requires a recycle of the app pool. Only when you recycle the app pool will SharePoint load the files again from disk. Otherwise it gets it from its cache.

OTHER TIPS

Taking a quick look at it (since this is a wall of a post :P), there are a few things that I noticed that MIGHT have an impact on this working or not.

I looked at your xml file, and it seems you have the ViewStyle and ViewBody tag, but no ViewHeader and ViewFooter. They are required to create a custome ViewStyle.

Another point, that may be the more glaring issue, is that you have these two lines of code:

  g_RequiredFields[6] = new Array;
  g_RequiredFields[6]["RequiredField"] = true;

You are passing in 6, but you need to pass in the ID of the custom ViewStyle you have created. So try changing 6 to 21. If I find any more issues as I go through the code, I'll let you know.
