I know I can filter a SharePoint list by adding ?FilterField1=fieldname&FilterValue1=value to the URL. Microsoft's documentation also lists a property FilterOperator1 that you can use if you want an operator other than equals.

However, if I add &FilterOperator1=Lt to the query string, I just get an error. How do I specify this property?


You need to call it FilterOp1 in the URL.

e.g. for less-than: ?FilterField1=fieldname&FilterValue1=value&FilterOp1=Lt

MSDN has the full list of operators.

  • Spent ages googling this before finding an example in another question. This seems to be completely undocumented. – John Fouhy Jun 16 '13 at 22:15
