Changing Table Filter Returns Blank Values

Posted on by kochbd

I have a dropdown that I want to change the source of based on a radio selection. Items property of the dropdown is set to the collection SystemNumbers. I have a table with 3 different columns that correspond to the 3 different radio options. When I select the 1st option, it correctly displays the items in the dropdown, but the other 2 radio options display a ton of blank records.

Here's what that looks like:

Here is the code I am using currently in the OnSelect function of the radio button:

ClearCollect(SystemNumbers, Switch(
 SiteSelector.Selected.Value,
 "AAA",Filter(SystemLookup[@AAA], Len(AAA)>6),
 "BBB",Filter(SystemLookup[@BBB], Len(BBB)>6),
 "CCC",Filter(SystemLookup[@CCC], Len(CCC)>6)
))

For reference, if I set the items property of the dropdown directly to BBB or CCC like this, it works correctly:

Filter(SystemLookup[@BBB], Len(BBB)>6)

For whatever reason the switch statement (I've also tried with IF statements) causes issues. Has anyone seen anything like this or know how to fix it?

This worked! I enclosed it in the ClearCollect statement I had originally, and then once I initialized the collection SystemNumbers with the column name "Value" it started switching the dropdown correctly. Thank you so much for the help!
Collect(SystemNumbers, {Value: ""});

Can you give a try like below:

ClearCollect(SystemNumbers, Switch( SiteSelector.Selected.Value, "AAA", Filter(SystemLookup, !IsBlank(AAA)), "BBB", Filter(SystemLookup, !IsBlank(BBB)), "CCC", Filter(SystemLookup, !IsBlank(CCC)) ) )

@kochbd - the column names need to be consistent. Consider using RenameColumns (not delegable):

Switch( SiteSelector.Selected.Value, "AAA", RenameColumns( Filter( SystemLookup, Len(AAA) > 6 ), AAA, Value ), "BBB", RenameColumns( Filter( SystemLookup, Len(BBB) > 6 ), BBB, Value ), "BBB", RenameColumns( Filter( SystemLookup, Len(CCC) > 6 ), CCC, Value ) )
