ComboBox Search Doesn't Work while Selection Works Ok

(0) Share

Report

Posted on by Kazanskyi

My data sources are Sharepoint Lists.

Here is a formula I use:

Filter([@SECurity_CATegories_PBI], CAT_TYPE = ComboBox2_1.Selected.Value)

It works perfectly with "Allow Searching" turned off, but once it's on, I can only see an empty field.

I thought it might be some delegation errors so I changed it to

Filter([@SECurity_CATegories_PBI], StartsWith(CAT_TYPE , ComboBox2_1.Selected.Value))

But nothing changed.

Help!

Hi @Kazanskyi ,

What type of field is CAT_TYPE ? If a Choice or Lookup column

Filter( [@SECurity_CATegories_PBI], CAT_TYPE.Value = ComboBox2_1.Selected.Value )

Hello @WarrenBelz,

In SharepointList settings CAT_Type is a regular string.

Hi @Kazanskyi ,

Assuming the drop-down selection exactly matches the CAT_Type Text field, the issue is that there is potential for a Delegation issue on Searching (Power Apps does not know how big the list will get) - If the filtered outcome is never going to be bigger than your Delegation limit, you can do this

With( { _Data: Filter( SECurity_CATegories_PBI, CAT_TYPE = ComboBox2_1.Selected.Value ) }, Sort( _Data, YourDisplayedFieldName ) )

Thank you for the idea.
The search field is still empty, unfortunately.

I tried to change the formula to distinct values, but it did not help as well.
Distinct(Filter([@SECurity_CATegories_PBI], CAT_TYPE = ComboBox2_1.Selected.Value),CAT_NAME)

With isSearchable turned off, both options work great.

@Kazanskyi ,

If you want Distinct values, you might try the process from this blog of mine.

Hi @WarrenBelz,

Ok, I got it. Distinct values are unnecessary as all the values in the column CAT_NAME are unique. I am testing all the options with no clever ideas.
Do you have anything else on your mind as to why the search doesn't work?

Have you displayed the correct field in your combo Box (Edit icon at right)

All seems correct. Here is a screenshot.

Please correct me if that's not what you mentioned.

@Kazanskyi ,

Probably my last shot as based on what you posted, it simply should work - I assume CAT_NAME is a Text field.

With( { _Data: Filter( SECurity_CATegories_PBI, CAT_TYPE = ComboBox2_1.Selected.Value ) }, Sort( _Data, CAT_NAME ).CAT_NAME )

Yes, CAT_NAME is a text field.
Unfortunately, it did not help.
