Making three fields required in a canvas app using if statements

Hello, 

 

I am trying to enable my submit button's display mode depending on the values of three fields.  My three fields in my canvas app are: 

 

Case_Number (text input)

Sessions (Drop Down)

Reviews (Drop Down).

 

I basically want to have something that states that if Case_Number is blank and both Sessions & Review Drop Downs Start with "Please Select...", then displaymode.Disabled.  But if they are then entered / selected - to make it displaymode.edit.  

 

How do I write something like that simply?

@ianallen13 ,

No frustration on my part, but this blog of mine may be worth reading - it may save you some frustration in the future. Are you sure you  have the Please Select  . . . exactly as it is in the drop-downs ? How about this

If(
   Len(Case_Number.Text) = 0 ||
   StartsWith(
      Sessions.Selected.'CU Sessions',
      "Please"
   ) ||
   StartsWith(
      Reviews.Selected.'CU Quarterly Reviews',
      "Please"
   ),
   DisplayMode.Disabled,
   DisplayMode.Edit
)

@zmansuri - Unfortunately that will not work.  The drop down fields are not blank to begin with.  They have "Please Select..." already listed. 

Hello @WarrenBelz  - I just gave this a go and i was very hopeful, but unfortunately it doesn't do exactly what I need.  It disables my submit button, which is great, but as soon as I start typing a case number into the case number field, it becomes enabled.  I need it to be for all three fields where they are satisfied.  Is that possible?  

 

Here is what I have so far:

If I use selected instead of selected text, I get read error squiggles. 

@WarrenBelz 

 

Here is my form:

So under the case number field, as soon as I start typing in there - the submit button becomes enabled.  Looking to have it where that, the session and the quality review need to be entered / selected before the button can become enabled.  Thank you for your help!

Hi @ianallen13 ,

This code

If(
   Len(Case_Number.Text) = 0 ||
   Sessions.Selected.Value = "Please Select ..." ||
   Reviews.Selected.Value = "Please Select ...",
   DisplayMode.Disabled,
   DisplayMode.Edit
)

assuming you have the Please Select  . . . exactly correct as per your default on the drop-downs) will not enable the button until both drop-downs have something else selected AND there is some content in the Text box. Have you checked this ?

Hi @WarrenBelz 

 

Here is what I just tried but sadly didn't work. 

 

ianallen13_0-1668552834096.png

If I do the one you sent over verbatim, I get the red error lines.  Sorry for being a pain, but I appreciate your help. 

 

This is what it looks like when I try yours.  Says 'Value' isn't recognized.

@ianallen13V2 ,

That is useful information - the issue is the output of your combo boxes (not the code logic, which is correct). What are the Items properties of the Combo Boxes ?

These are excel tables that I have the drop downs connected to.  Does that help a bit?  

 

Thank you again!
