Convert code from a static html to place into a repeater

Dcode warner asked on March 24, 2017 17:59

  1. How can convert the below code into ASCX? {%Documents[CMSContext.CurrentDocumentParent.NodeAliasPath].Children[Documents[CMSContext.CurrentDocument.NodeAliasPath].NodeOrder - 2].NodeAliasPath#%}/

  2. Also need to implement next/previous into blog to go to the next posts. The below only works in the current month. I need all months and all posts to be included.

    < a href="{%Documents[CMSContext.CurrentDocumentParent.NodeAliasPath].Children[Documents[CMSContext.CurrentDocument.NodeAliasPath].NodeOrder - 2].NodeAliasPath#%}/" title="previous room">Back < a href="{%Documents[CMSContext.CurrentDocumentParent.NodeAliasPath].Children[Documents[CMSContext.CurrentDocument.NodeAliasPath].NodeOrder].NodeAliasPath #%}/" title="next room">Next

1: Although a bit messy (you may want to create a Custom Transformation Method to contain this logic)

If(Eval<int>("NodeOrder") > 1, CMS.DocumentEngine.TreeHelper.SelectSingleNode(Eval<int>("NodeParentID")).AllChildren.Where(x => x.NodeOrder == (Eval<int>("NodeOrder")-2)).FirstOrDefault().NodeAliasPath, "")

2:

Since you want to go beyond months, i would recommend you create a custom transformation method since the logic is hard to fit into 1 line, but if you did want to...it would look like tihs mess

CMS.DocumentEngine.DocumentHelper.GetDocuments("CMS.BlogPost").Path(CMS.DocumentEngine.TreeHelper.SelectSingleNode(Eval<int>("NodeID")).Parent.Parent.NodeAliasPath+"/%").OrderBy("BlogPostDate").Where("BlogPostDate > '"+Eval<DateTime>("BlogPostDate").ToString()+"'").Take(1).FirstOrDefault().NodeAliasPath

With the note that the above will ERROR if it's the latest blog post since there isn't one that beyond it, hence why a custom transformation method that can check to see if the object is NULL before calling it's NodeAliasPath would be helpful.

This should be the documentation on how to create custom methods for transformations in K7

You'll probably need to adjust my logic then, i put it in Kentico 10, so the methods and classes are probably a bit different, Kentico 7 is pretty ancient.
