But so far I haven't had any success. All I'm trying to do is basically display "Input number" if a field is left blank and the form is submitted. I realize this probably isn't super difficult, but try as I might, I haven't been able to figure it out. Go to Solution. I covered it in this video Conditional Formatting in PowerApps. View solution in original post. Sorry, I was out all afternoon. Can I recommend you do it slightly different? Leave the submit button disabled until the form is filled out. If not happy to help more. This video covers a lot of these concepts. Conditional formatting in PowerApps. Maybe give it a watch, give it a try, and let us know if you get stuck. Everything you want to do seems to be there. Thanks for the input! I'm still a bit confused as to how what you suggested will allow me to change the text that is displayed on error. Am I missing something? Maybe I misunderstood? I thought your goal was to show a message that says something like "This isn't a valid email address, please try again" or "Name is a required field". Is that your goal? First, thank you so much for taking the time to get back to me on this and for your help in figuring this out. I really do appreciate it! My goal is to display the error message, "Input number" if a field is left blank and someone tries to submit the form. Currently, the default error message is displayed, and I can't figure out how to change it to what I want. Click for the top entries.

Blank, Coalesce, IsBlank, and IsEmpty functions in Power Apps

I am creating a form which the data will get saved to a collection and i would like to disable the button until all the fields are filled in. If all the fields are empty then the button is disabled. But as soon as text is entered into 1 of the fields, the button is enabled regardless of the fact the other fields still need data. The form consists of 4 dropdowns and 2 textinput fields. Go to Solution. Your statement reduces to disabled if all criteria are met. What that means is that if one of the criteria is false, then the entire statement is false and the button is enabled. What you need is for the button to be disabled unless all criteria are true. View solution in original post. You can use as many as necessary to complete the logic of the IF function.

What a great last few days for PowerApps! I hope you have been enjoying the announcements in the Spring Update Blog bundle. Many of you will yawn. But for some this will be a big deal because PowerApps can now write Null values to databases. We mark features in this manner when:. All of these reasons apply in the case of Error handling. So we are going to keep the feature turned off for both old and new apps, and allow those of you who want to play with it and desire its benefits to opt-in. The description says we will be turning this feature on for all apps in September. We do plan to eventually turn this on for everyone, without a switch, but only when the time is right. This feature will not just disappear. This feature is not experimental — we are done with it, it is here to stay, and you can you depend on it. This was merely a convenient place to put the setting. It is no secret that PowerApps is inspired by Excel. But there is one aspect of Excel that PowerApps had not embraced: error handling. Errors in PowerApps would result in a simple Blank or Null value. Which caused issues because Blank values are legitimate non-error values in most databases. We have a small number of sources for errors at present. Division by zero, converting non-numbers to numbers, Text function usage with an invalid locale string. We are retrofitting some of the other functions to also return errors, such as Patch. To ease the transition, errors operate like Blank values in most contexts.

I need to disable the submit button if the empty value is selected. I figured out how to disable the button for the "traffic" value but I do not know the name of that empty value to make my formula work. See screen shots. Go to Solution. View solution in original post. Let me know if that works out for you. I need to disable the submit button both if the textbox is blank OR if the dropdown value is blank. Right now both of the below formulas work on their own but I've tried to figure out how to combine them and it's not accepting anything I type. I was literally up for hours attempting every if statement variation I can think of so thank you for your speedy reply. You saved me time! I will post an explanation of the nested statement, hopefully tonight but definitely by tomorrow. Okay, here we go on this explanation. This may be something you already know, so forgive me if this is too basic but I thought I would get into the And and Or functions. Without going too in depth or getting to basic, these functions compare two or more Boolean true or false statements and return a true or false based on the result. For Andif all the compared statements are true, it returns true; otherwise, it returns false. For Or if just one of the compared statements is true, it returns true; otherwise, it returns false. To return true, both of these statements must be true i. Otherwise i. If it never becomes visible i. Otherwise, it will return false. Now, the result of the Or statement is what then sets the true or false section of the If statement. Otherwise, it will be enabled. I am typing this on very little sleep so I hope it makes sense. Feel free to comment back if I need to better word things or if it was total gibberish. So, with that understanding, I was able to add a 3rd condition on the Or Statement that I needed to add. I would not have been able to do so without your teaching so thank you!
