Stop form submission if fields are blank

[RHADAVE]

Sorry if this has been posted before. 

I have a form linked to a sharepoint list. Im trying to make the forms mandatory and reading around i can use displaymode on the button with this command 

If(IsBlank(DataCardValue2) && !IsBlank(Title) && !IsBlank(DateValue3) && !IsBlank(HourValue3) && !IsBlank(MinuteValue3) && !IsBlank(DataCardValue21) && !IsBlank(DataCardValue22) && !IsBlank(DataCardValue25),DisplayMode.Disabled)

But its not working. have i done something wrong?

Thank you in advance

Hi, select the datacard, the select Required from the menu and change to true

You need not do all the comparisons (and, you will want to compare the property of the control, not the control - i.e. DataCardValue22.Text, not just DataCardValue22).

If your field is required in the form, then simply set your submit logic to:

  If(yourForm.Valid, SubmitForm(yourForm))

It will do all the other comparisons for you.

I hope this is helpful for you.

Oh, and noticing that you were using this for the DisplayMode...so the formula would be:

  If(Form7.Valid, Edit, Disabled)

Hi mate, using

  If(Form7.Valid, Edit, Disabled)

As soon as i fill in "requester" and "title" the button goes to orange which is the enabled colour...

This will most likely be because you have not set the other fields as required. the Form7.Valid function is deciding if the form is ready to go, so if for example all fields had required set to false, your button would always be orange / in edit mode, but if all fields were set to required (true) the button will not change to orange / edit mode until the last input value has been filled out in the form.

OMG!!! IT WORKS!!! Yeeeeeeeeeeeeeeaaaaaaaaaahhhhhhh! 

You have no idea how much i appreciate the help. 

I have never used PowerApps until 2 weeks ago, and its been a steep uphill climb trying to build this. Last bit of coding i touched was visual basic 16 years ago in I.T boot camp!

Just wondering, is there a command i can use to display a message if the disabled "send request" button is pressed when the form is blank, instead of using a tool tip. Just a friendly prompt if someone has missed something out. It Avoids me getting lots of phone haha

thank you

If it is disabled...then users can't click on it!
