Hi Team,

I am working on a power app where I need to to make sure individual controls on the form are not blank, I am able to validate not blank(using IsBlank), but I am unable to show the validation message for individual/each control, able to show a single validation message for all controls. I am using a SQL Server data source to fetch the data, using patch function(on a button click) to insert the data.

Please let me know if more information is required.

Thanks,

Salil

Hi @SalilSingh ,

Below are 2 possible ways to achieve this based on your scenario:

Scenario 1: If you have many fields and would simply don't want any fields to be blank. Then make them required.
Whenever you patch or submit the Form and those fields are blank, it will throw blank error that needs to be filled in order to submit the form.

Scenario 2: If you need custom way of handling some fields that make not be required but it is in some cases based on xyz conditions.
Then you can use this code on your Submit Form button
UpdateContext({IsBlankFieldsPresent: (IsBlank(Field1.Text) && IsBlank(Field2.Text)) }); If( !IsBlankFieldsPresent, SubmitForm(Form1); )

For all your Fields,
on default Error label or custom Error label,
Use this on Visible property
If(IsBlankFieldsPresent && IsBlank(Self.Text))

The error will be shown when there's error on the form and self values are null

Hope this helps 👍🏻
