Basically i have a gallery with three input fields in each item. I want first input_field to allow only 11 characters , similarly second input should allow < 6 characters and third one should allow only 1 character.

Now i want to check in the whole gallery if any input field is not obeying the rule , i want to hide the submit button in that case.

For Better Understanding ----->

GALLERY

1 item = 3 input fields with the above validation rules mentioned.

2 item = 3 input fields with different validation rules.

And the submit button should be disabled in-case any input field is not following the validation.

I know its complex and thats why I need some help.

Hi @PAJ,

You can actually enforce the maximum allowed characters in a Text Input by using the MaxLength property of that control. The first would be set to 11, second to 5 and last to 1. Typing more characters will simply not be possible within those inputs.

In case you don't want to enforce the max length via that property, you can use the following code in the DisplayMode of the submit button (change to the correct control names):

If(
 CountIf(
 Gallery1.AllItems,
 Len(TextInput1.Text) > 11 || Len(TextInput2.Text) > 5 || Len(TextInput3.Text) > 1
 ) > 0,
 DisplayMode.Disabled,
 DisplayMode.Edit
)

In case you don't use the MaxLength property, you may want to color the Text Input's border red when too many characters have been entered:

//BorderColor property of TextInput1
If(
 Len(Self.Text) > 11,
 Color.Red,
 RGBA(0,18,107,1)
)

If this solves your question, would you be so kind as to accept it as a solution & give it a thumbs up.

Thanks!
