Conditional Formatting based on empty Date column

[Amapola67]

Good Morning

I have a SharePoint list and I want to apply conditional formatting if an item hasn't been submitted, in which case a Date field will be empty.

I have applied other formatting based on whether a column contains data by simply picking the column, 'is equal to' or 'is not equal to' and then leave the last field blank. But that doesn't seem to work with a Date field.

I've also tried to put the condition as 'Column' 'is not equal to' '1/1/1990' - in the hope that picking a date long ago, nothing will match but this doesn't work either.

I have other conditions so I didn't really want to go to JSON. I don't know enough to work out how to put 3 conditions together!

Is there any way to conditionally format based on the empty Date value?

Thanks,

Christine

@Amapola67 you can format the date column in advanced mode as follows:

{
  "$schema": "https://developer.microsoft.com/json-schemas/sp/column-formatting.schema.json",
  "elmType": "div",
  "txtContent": "@currentField",
  "style": {
    "background-color": "=if(Number(@currentField) == 0, '#541417', 'green')",
    "color": "white"
  }
}

@RobElliott Thanks!

But that only formats that field while I'm trying to format the entire item. As a work around, I've introduced a Status column but that means I need to manually update it ..

@Amapola67 If you want to format entire row based on empty date column, you have to use view formatting.

Example:

{
  "$schema": "https://developer.microsoft.com/json-schemas/sp/view-formatting.schema.json",
  "additionalRowClass": "=if([$StartDate], '', 'sp-field-severity--severeWarning')"
}

Similarly, you can apply any of the predefined classes instead of 'sp-field-severity--severeWarning' as given in below links as per your requirements:

1. Predefined classes
2. Reusable SharePoint Online Classes for Modern UI

As I have multiple conditional formats, I need to put your code into what was generated. I made the read bit Date is not some date but it generates an awful lot of code compared to your string.  (I know from VBA that a well-structured code is easier to read but JSON seems to go a bit over the top! It's no longer well structured, it's blown up.)

And quite frankly, I can't make head or tail of the code.  There's no if that I can see. 

Can I incorporate your code string in this?

          {
            "operator": ":",
            "operands": [
              {
                "operator": "==",
                "operands": [
                  {
                    "operator": "Date()",
                    "operands": [
                      {
                        "operator": "toDateString()",
                        "operands": [
                          {
                            "operator": "Date()",
                            "operands": [
                              "[$EnteredPhoenix]"
                            ]
                          }
                        ]
                      }
                    ]
                  },
                  {
                    "operator": "Date()",
                    "operands": [
                      {
                        "operator": "toDateString()",
                        "operands": [
                          {
                            "operator": "Date()",
                            "operands": [
                              "Sun Jan 01 2012"
                            ]
                          }
                        ]
                      }
                    ]
                  }
                ]
              },

@Amapola67 "But that only formats that field while I'm trying to format the entire item" - it would have been helpful if you'd said that in your original post!

@RobElliott 

Sorry, must be my wording. I have been trying to avoid learning SharePoint .. I thought 'item' was an entry, i.e. the line. Vs. column which is a field?

So when I said I'm trying to format the item, I meant I'm trying to format the line. Trying to speak SharePoint and obviously failing.

No need to apologise, I sounded irritated which I didn't mean to but one of our staff had done something incredibly stupid on one of our sites just before I posted.

@RobElliott Good staff is so hard to find these days 

I'm learning more about SharePoint these days than I ever wanted to know!!

Have a good day!

@Amapola67,

I realize this is a bit dated now, but I believe this can still be done with the out-of-the-box conditional formatting style editor --for those interested in just formatting an individual date column, by simply choosing the "is between" comparison and leaving the date selections empty.

@Kregg1122

Nice. I will have to try that. - Never too late to learn! 

Thank you!
