SSRS error- Exception Details: System.InvalidOperationException: Operation is not valid due to the current state of the object when you select all parameter values.
I never used to face this issue as I was able to select all and get all the values.
The values are basically codes -
e.g xyz123
xyz234
xyz456
but today all of a sudden its showing this error
As per google it says because of Microsoft security patch.
The dataytype of this column is string
