The timing is just impeccable. Right in the middle of a project and this has given me more ideas for validating input fields. Yes, the IsMatch video is needed, Shane... Thank you

@ShanesCows Год назад

Thanks Douglas and good luck!

@chrisundery6132 Год назад

Great as ever Shane. Literally had an accidental entry the other day as the user missed a field that should be set to mandatory. Can now easily fix. Keep them coming.

Thanks Chris! 😎

The timing on this is great! I'm trying to control data being put into a PowerApp and visualizing it in PowerBI...well timed. And your answers are more useful than ChatGPT (Yup, I used it as an aide) And yes, please, an in-depth isMatch video would be appreciated.

You are welcome Franks. Thanks for the feedback.

@manojroy8862 Год назад

Really, helpful video to understand the basics of controls and work to it, this would also help the freshers to understand the properties of the controls and how to implement it.

I would love an IsMatch video (and especially if it includes a very quick tutorial on regex expression syntax?) Appreciate all your work!

@ShanesCows 11 месяцев назад

Noted. In the meantime Tracy I would ask ChatGPT to help write your Regex expressions. It is pretty good at those types of things that us mortals have no clue how to do. 🙃

Nice video as always--i always smile every time you correct your own words. Anyway, it seems i need your assistance here! I want to build an app to take care of the exit clearance process in my office. I do watch a lot of videos on how to build an app using this PowerApps but I still couldn't figure out how to make this exit clearance into the app. Any advice from you would be very much appreciated. Cheers!

Roy I am sorry, I don't follow what you are looking for.

@ophemtech Год назад

I must confess that this is really an angel coming to my aid cuz i just hitted this validation problem. though if i had continued with using my head and tweaking things, i couldve gotten it but maybe not as better as you taught it here. but i really do have a problem, i seem to not be able to create a dataverse or sharepoint, and i still dont know why i can't create that, is it that i dont have access to do so or what do you think could be the problem. but anyways, thank you for these tutorials, its life saving

@ShanesCows Год назад

James do you need to add a connection to SHarePoint or do you need to go to SharePoint and create a site. Sorry, I don't follow what you mean by cannot create a SharePoint.

@ophemtech Год назад

@@ShanesCows uhm the issue is, I haven't been able to connect to a SharePoint. And from your videos it seems you create a SharePoint site which I don't know how to do. So I'm clueless on how to do that as well as connect to dataverse created by me.

@ShanesCows Год назад

James from Office.com click on SharePoint and should be able to create a new site. This would be your own SharePont site. Then you could create a SHarePoint list there. Finally you would add that as a connection to your Power Apps app. I wonder if my free 101 class would help you with the basics? training.powerapps911.com/courses/power-apps-and-power-automate-getting-started

Great video! Though since the lblWarnEmail only shows up when the email is invalid and not blank, if the email is blank the user could actually click on the button Thats a demonstration so no one cares but it might surprises some people that copied pasted haha

@lwhite3225 6 месяцев назад

Great stuff! I use form.valid to set display mode for buttons. Does form.valid pick up IsMatch errors? Or do I need to add that to the button's display mode property? Not sure this makes sense to anyone but me.

@ShanesCows 6 месяцев назад

I haven't tried but I am going to guess that Form.Valid does not identify IsMatch errors as they are logic outside of the Forms own logic. My guess. :)

@josecarlosbenitezmeyer645 8 месяцев назад

Hi How can I validate that the new data be equal or greater than the data already stored in a data card ?

@zekeskinner3346 Месяц назад

Hey Shane, How would I disable a button with a form field instead of a table field. I am using powerapps to automate an application into a sharepoint list and I need to make it to where the data field that is required will not allow me to continue in my application without filling out that portion. I have tried the IsBlank and IsEmpty but neither are working.

I'm needing to validate a date field by radio button choice. If the radio button choice = "No", date must be after today, if the radio button choice = "yes", date must be before today. Any help is greatly appreciated.

@ShanesCows Год назад

If((Radio.Selected.Value = "No" And datepicker.selectedDate > Today()) Or (Radio.Selected.Value = "Yes" And datepicker.selectedDate < Today()), "Good", "Bad") Something like that should get you started :)

Can anyone out there give me some insight into this issue? On Submit, it says that 'field_3" is required. all of the fields on the form have been completed, and none are named field_3. By default the MI field has Displayname: DataSourceInfo([@AccessRequests],DataSourceInfo.DisplayName,"field_3") Other fields likewise have display names of field_1, field_2 etc. But again, all fields have been populated, so this issue is baffling me.

@ShanesCows Год назад

Tess it sounds like your Data Source has a field named Field_3 and the data source is required. I would start by checking that. I assume it is SharePoint? That is a quick thing to check. If you find it then you can decide do you want to change the field in SharePoint not to be required or add the field to your form in Power Apps.

@TessAlmond Год назад

@@ShanesCows None of my fields are named 'Field_number" . The datasource (SP list) fields are appropriately named, as are the fields on the form. In PowerApps on this field and a few other fields, the DisplayName property of the datacard: DataSourceInfo([@AccessRequests],DataSourceInfo.DisplayName,"field_9") That is the only place I see reference to field 9.

@ShanesCows Год назад

Tess watch this video real quick. It will show you how to see your columns real names, you most likely imported from Excel and the system names are field_3 even though you think it is Department. :( ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-mwXnJUkTug0.html
