Incomplete dropdown values

[Neil6]

Hi Everyone,

I have a drop down control on the app that I am currently developing. And my issue with this drop down is that it doesn't seem to get all the values from the SQL server database.

Here is a screenshot of the drop down control:

As you can see, there are only two values present, when it should be 3. What's missing is the "Probationary" value.

My script on the items  property is simple, it queries the Employment_type column and I used the Distinct function to filter out duplicates. Here is the screenshot of the Items property:

I only tried refreshing my data source, still no luck.

Hope you can help me solve my problem.

Thanks in advance

HI @Neil6 ,

The Distinct() Filter is not Delegable, so I would assume that the missing item is not present in the first 500 (your can increase this to 2000 in Advanced Settings) records.

If you only are going to have limited options of values, then hard-code them

["Rsgular","Third Party","Probationary"]

Hi @WarrenBelz ,

I tried to query the top 500 on my data source and the value "Probationary" is included. Also, which property in the advanced settings should I change?

Best regards

I created a view on SQL which queries the column Employment_type and filters it. It turns out I have 4 distinct values. Though they are now all present in my drop down control. however, i still have an error on the update property.

What should be in the update property of my Drop down control?

Hi @Neil6 ,

What type of field are you writing back to, and what is the Items property of the drop-down and what is the error message?

Hi @WarrenBelz 

The data type is varchar.

Here is the Items property. I'm calling a view from SQL database.

Sort('[dbo].[DrpDwn_Emp_Type]', Employment_Type,Ascending)

Here is the error: "Name isn't valid. This identifier isn't recognized"

Hi @Neil6 ,

I think you need 

DataCardValue4_1.Selected.Employment_Type
