PowerApps show error message to user if it's not within the range.

[Anonymous]

Hi Team, 

I have created an app link to sharepoint list. Under Title colum, it contain numbers and alphabets + number as per below. 

 

On my Powerapps screen, searchbox, let's call it textsearchbox1. i want it to show error message in red color if user key in any number that is not in the SharePoint list. For example, in my sharepoint list Title column it contain number 78,79,IT01 and AJ0001. If user key in BA on textsearchbox1, a red error message will show. 

Any suggestion will be much appreciated 

Thanks

I'm trying with 

If(Or(IsBlank(TextSearchBox1.Text),If(And(!IsBlank(TextSearchBox1.Text),!IsMatch(TextSearchBox1.Text,"Title")),true,false)),false,true)

Nothing change on the text box. it is always remain hidden

Hi @Anonymous ,

Based on the formula you provided, I think there is something wrong with it. I have made a test on my side, please consider take a try with the following workaround:

Set the Visible property of the ErrorMsgLabel to following:

If(
   !IsBlank(TextSearchBox1.Text) && Not(TextSearchBox1.Text in '20190325_case13'.Title),
   true,
   false
)

On your side, you may type following formula (set the Visible property of your ErrorMsgLabel control to following😞

If(
   !IsBlank(TextSearchBox1.Text) && Not(TextSearchBox1.Text in JobCodeMatrix.Title),
   true,
   false
)

Please consider take a try with above solution, then check if the issue is solved.

Best regards,
