Symptoms
We are facing some issue in the filter feature of list view where we have employee ID column is one of the search criteria.
The issue is that the user is not getting any search results when he gives space before or after the EmployeeID (DataType = number) in the search text box.
As per our analysis , K2 identifies the space as a string and so the reason it doesn't give any seach result.
one sample employee ID which give issue : --> ' 12345678 '
Diagnoses
I believe we can't modify this system control to trim the value for the filter.
Resolution
Disable “Enable Filtering” then and use a TextBox control then use the rule and expression to filter the list.
