I want to allow on a list web part a mutually exclusive selection for the items, so that I can force the user to select a single item and retrieve the item id using the SP.js JSOM.

There is a problem in achieving this:

1) Leaving default view configuration: I can use SP.js to retrieve the items but the user will be able to select multiple items.

2) I can disable in the view the Tabular View option (Allow Individual item checkboxes) to force the user single selection, but then I will not be able anymore to retireve a selected item, as it seems that selection is removed at all.

I need to execute a single custom action on a single selected item (for example through a button on the page); that's why I'm thinking about a way to force single item selection.

Please advise.

  • What do you want to do (with the id) when the user clicks an item? Commented Aug 4, 2015 at 13:58
  • @DannyEngelman for example read some field from the item. Commented Aug 4, 2015 at 14:49
  • So you mean: You have a View which does not include all fields and you want to retrieve a field? Then what do you want to do with it? Commented Aug 4, 2015 at 14:54

There is all sorts of ways to skin this cat.

  • Add a Custom Action which can only be used once
  • Use CSR to render a button for each item

This all requires some coding.

For quick prototyping I stuff HTML+JavaScript in a Calculated Column (and then instruct the 5 US$ an hour programmers in India to replicate the behaviour in more solid code, although to be honest most often the client is fine with my ductape approach)

  • Create a Calculated Column
  • Set the datatype to Number
  • Paste the Formula

    ="<button class=""myButtons"" style=""cursor:pointer;"" onclick=""{"
    &"  event.preventDefault();"
    &"  var TR=this;while(TR.tagName!='TR'){TR=TR.parentNode}"    
    &"  var id=TR.id.split(',')[1];"
    &"  alert(id);"
    &"  [].forEach.call( document.getElementsByClassName('myButtons') , function(me){"
    &"      me.style.display='none';"
    &"  });"
    &"}"">My ID is ... </button>"

You can click a button once, it then hides all buttons.

For more inspiration see how we recenlty used this to kick off a Workflow for an Item:
Can I add a start workflow link to a column in a list view?

CalcMaster Bookmarklet to edit Formulas

It is a PITA to debug Calculated Columns. Because you don't get feedback until you save a Formula and you end up having to click multiple times to get back to your Formula.

I have written a small 'CalcMaster' bookmarklet which hooks into the formula-editor and does a save of the Formula on every keypress; giving immediate feedback.
