Posted on by Masum172

Hello PowerApps Community,

I am looking for some help on disabling this button unless all combo boxes & Text Inputs have input.

Here are my OnSelect values

(ComboBox1.Selected.Value, ComboBox4.Selected.DisplayName, TextInput1.Text, User().Email, TextInput2.Text, ComboBox4.Selected.Mail);

It would be a massive help if someone can advise as it is driving me nuts! I have tried a few suggestions online but unfortunately had no luck, any help is appreciated thanks!

HI @Masum172 ,

Something like this should do it

If( Len(ComboBox1.Selected.Value) > 0 && Len(ComboBox4.Selected.DisplayName)> 0 && Len(TextInput1.Text) > 0 && Len(TextInput2.Text) > 0 && Len(ComboBox4.Selected.Mail) > 0, DisplayMode.Edit, DisplayMode.Disabled )

@WarrenBelz solution will work. But when you start getting a large number of controls to validate against I usually find its easier to set the OnChange events of the controls themselves to increment and decrement a counter of how many controls are empty. Then set the button to activate if the counter is 0. It takes a bit of planning, but its much easier to maintain when you get a large number of controls on the screen because it isolates the logic down to each control.

Hi WarreBellz,

Thank you for your suggestion 🙂

I have tried this and looks as though it likes the formula but nothing happens? The status of the button remains enabled and doesn't change for odd reason not sure!

Hi Pstork1!

Thanks for your suggestion!

Do you mean set an OnChange command for each Combo box & Text Input values and then setting the OnSelect for the button accordingly? how would I accomplish this please.

Thanks for your help so far!

Yes, Set an OnChange event for each control that either increments or decrements a variable based on whether it is filled in or deleted. Then use the variable with the total count to determine whether all the controls are filled in.

Lets say you have 6 controls on the page and in the OnChange event of each control it increments a counter called varCounter each time the control goes from empty to filled in. When varCounter reaches 6 you make the button active. If you add a 7th control you set its onChange event the same way and increase the check on the button to 7, but you don't have to change any other control or maintain a complex list of If statements in the button.

Just to follow up on this. Here is a sample of the code I use.

In App.OnStart

Set(requiredFields,<<Number of Fields Required>>); Set(targetRequireds,<<Target fields not empty at start>>);

In each required control's OnSelect

Set(currentValue1,Len(Self.Text))

In each required control's OnChange

If((currentValue1=0&&Len(Self.Text)>0),Set(targetRequireds,Sum(targetRequireds,1))); If((currentValue1>0&&Len(Self.Text)=0),Set(targetRequireds,Sum(targetRequireds,-1)));

In DisplayMode on Submit Button

If(targetRequireds >= requiredFields, DisplayMode.Edit, DisplayMode.Disabled)

If a Required Control is changed from blank to filled in the targetRequireds will be incremented. If changed from filled in to blank targetRequireds will be decremented. Otherwise the count won't change. There is a CurrentValue# for each required control.

Thank you all for your suggestions 🙂

Unfortunetaly, I haven't managed to get far with this after trying WarreBellz solution, it accepts the formula fine but buttons are still enabled so not exactly sure what the code is doing. I am really new to Power Apps so apologies If I do ask questions which may sound stupid (This is my first app)

@Pstork1 Thanks, I'm not sure exactly where to start with this one and don't want to risk breaking any controls in my app as will end up staying up a whole night to try and figure out where it went wrong! 😞
