How to format date column in DetailsList?

[kthirapatpibul]

By default, the date column in a Fluent DetailsList show both date and time, how do I format the date so that it only show the date? Also, it seems that null date are being displayed as 12/31/1969, how do I make it show "blank"?

Hi @kthirapatpibul,
You can use AddColumns. E.g.

1. Edit the Items property to include an additional column that formats your date:

AddColumns(
Accounts,
"ColDate",
Text('createdon',"yyyy-mm")
)

2. Add the new date column to the Fields property by clicking on Items
3. Update your columns definition to display the 'ColDate' property - but set the ColSortBy property to the original date so that you can sort by the real date field.
4. If you were using automatic sorting - you will now need to change to use manual sorting as described by https://learn.microsoft.com/en-us/power-platform/guidance/creator-kit/detailslist#manual-sorting

Hope this helps!

Hi Scott,
This is exactly what I need. I already have a filter statement in the Items property and I can't get the syntax right to include both the filter and the add column statement. If you could let me know how to do this that would be great.

Kind Regards, Craig

Hi @scottdurow,
in Yours solution we will get problems with delegation limits. Is any other way?

I use date only and working totally fine so far for around 2k records .

With Addcolumns? Check the "Data row limit..." and compare with yours number of records.

I'm currently out of the office. Yes with AddColumns, I keep at 2000 row limit. And records is around 650-800. It was more than 2000k records and I redesign tables to reduce duplicate records.

Sometimes when I'm working in coding, no delegation when I use AddColumns(), With() as well as collection, just you need to try different techniques. I would suggest you to try out with collection. If still facing same issue probably data type issue.

if still facing same issue then try add new column for date only, do not delete that column if you are already using that column in production.

I explain why I need extra column. I'm try to prepare some kind of time tracker app for Production Dept.
The dataverse table has columns
Data_start (date and time)
Data_finish(data and time)
Operation_time (this field is a calculted: DiffInMinutes).
With data source as a raw table from Dataverse I got in detail list some value in Data_finish where fiels is empty.
Thats the only reason*.
Maybe there is some othere way to avoid this issue. I dont know.

*Of course, it would be nice if I could fully customize displaied data.

There is a solution, you need to try different techniques. Usually collection solve some delegations try below.

ClearCollect(
colTracker,
ForAll(
Tacker,
{
DateStart: Data_start,
Datefinish: Data_finish,
Operationtime: ….
}
)
)

Then add colTracker into Detailslist.item
