I am developing an app in Teams - power app.

Want to disable the submit button till the mandatory field is not filled.

Tried to control it via Dataverse table, by selecting Colum Required property to : Business required.

But seems it has no effect, may be updated the property later

Therefore, trying to control it via, So if the field is not filled/Blank, the submit button will remain disabled.

Below is my code and error image on the screen,

If(

IsBlank(DataCardValue1.Value) || IsBlank(DataCardValue1.Value), DisplayMode = DisplayMode.Disabled, DisplayMode = DisplayMode.Edit)

pls. guide correction

@MIA27

Sorry. It was a simple problem, but it took us a long time because of misunderstanding . I hope you understand.

.Text obtains value from both number format and text format. Number format is used for real-time validation during input.

Text – Text that appears on a control or that the user types into a control.

Applies to Add picture, Button, Check box, Export, Import, Label, Text input, and Timer controls.

Value – The value of an input control.

Applies to Check box, Radio, Slider, and Toggle controls.

Does ".value" of Text Input field work?

Thank you for your support , at last it worked ... Oh.....

Just for my learning, Its strange :
The code accepts .value for Text Format field
The code accepts .Text for number format field
surprised, as it is opposite method acceptance.

Any learning link or material to understand more on this,

Best regards

If any one of the two is empty, it is disabled" - I misunderstood the condition

Oh.. I didn't noticed Value was used instead of .Text. Text is correct.

Re: How to Keep Disabled the Submit Icon till DatacardValue is empty

sorry,
Can not understand what mistake I am doing, applied the revised code (.value did not accepted was underlining red for error), so applied the below and no error lining but still not the perfect result.
It gets applied for datacardvalue1 but dont get in effect if the datacardvalue5 is blank.
Below is the image

note: datacardvalue1 is a text field
datacardvalue5 is a number field

If(
IsBlank(DataCardValue1.Value) && IsBlank(DataCardValue5.Text),
DisplayMode.Disabled, DisplayMode.Edit)

Can notice field SvcSMR is blank, still the Tick mark Icon is enabled

Please guide

Thank you
Applied the code, it accepted, no error underline now.
BUT has no impact on the result.
For test purpose, on the previous record, if removed the value from field and made it blank, found it has no impact on the Icon, It remained enabled. While the requirement is what ever the Form Mode be (Edit, View, New), If these 2 fields blank, it should be disabled,

I dont know if I am approaching the requirement in the right way.
Please guide
