If() function to evaluate multiple unrelated conditions in your data card.
If you want to validate that the text input is not blank and has more than 3 characters.
You can use this formula in the DisplayMode property of the data card:
If( IsBlank(TextInput1.Text) || Len(TextInput1.Text) < 4, DisplayMode.Disabled, DisplayMode.Edit )

Disable the data card if the text input is blank or has less than 4 characters, and enable it otherwise.

If you have any questions or feedback, please let me know. Have a great day! 😊

You could also use it for Required
If( Len(TextInput1.Text) > 3, true, false )

@MudassarSZ365 - I'm not sure what you're using to generate these answers, but data cards do not contain a Valid property.

@Mikellas - I would suggest that you take @SpongYe's advice here in terms of adapting the Required property to carry out this validation.

Hi @Mikellas ,
First Solution Attempt: @PowerYsa suggested using the If() function in the DisplayMode property to disable the data card if the text input was less than 4 characters. However, @Mikellas clarified that they did not want to disable the card but wanted it to show a validation error.
Second Solution Attempt: MudassarSZ365 proposed using the "Valid" property in the data card, with a formula Len(DataCardValue.Text) > 3 to check if the text has more than three characters. However, this approach was later corrected by another community member, stating that data cards do not have a 'Valid' property.
Third Solution Attempt: The same user, MudassarSZ365, then suggested adapting the Required property with an If statement. But @Mikellas expressed confusion about this solution, fearing it might only make the field not required rather than enforcing a character limit.
Final Suggestion: @timl recommended adapting @SpongYe's initial advice to use the Required property for validation. This approach aims to validate the character count without disabling the card or breaking other controls.
The conversation highlights the iterative process of problem-solving in community forums and the need for clear understanding of PowerApps functionalities and properties.
Best Regards,
Hassan Raza
