CRUD in Single-Page (Tablet Mode)

Monday’s Guru Best Practice:


PowerApps Group has provided an excellent Phone-Layout 3-Screens CRUD Apps and generate automatically using existing data.


For PC-Tablet Layout, it is yet to be included by PowerApps Group.


Nevertheless, 3-Screens CRUD may NOT be so practical for Big-Screen devices. Hence, I have resorted to making app for PC-Tablet Layout with ONE-SCREEN CRUD, so that it looks neat, faster response, no-navigation and hopefully, with less resources used, the apps will response much more smoothly.


Step 1:

- Create a Database, e.g: TableMMD


Typical Equipment Reg List (as of ISO 9001: 2015 QMS 7.1.5)Typical Equipment Reg List (as of ISO 9001: 2015 QMS 7.1.5)


Step 2:

- Design a simple Layout, with:

  • Title, BackButton and AddNewButton
  • Headers for each fields
  • Gallery with TextInputs
  • Gallery with DataSource, EditButton (To cover the whole record, with No-Fill Color)
  • SaveButton & CancelButton

Step 3:


Connection to DataSource - TableMMD


Link to datasource:

Gallery.Items (DataSource😞




UpdateContext({rst: false}); UpdateContext({rst: true, EquipMLH: 664, EquipMLY: 104, AddPopUp: false})


Gallery.Items (with TextInput):


TextInput.Reset: rst



Y: EquipMLY

Height: EquipMLH

[Purpose: to Re-Size Gallery to show/cover Gallery(TextInput) Area]


Button.OnSelect:  [Inside Gallery.Items (DS), Color: No-Fill]

UpdateContext({AddPopUp: true, EquipMLY: 166, EquipMLH: 602, EditEquipMaster: ThisItem})



If(ThisItem.IsSelected, RGBA(255, 255, 1, 0.2), RGBA(0, 0, 0, 0))

Click On (Invisible Button): Any Record (inside Gallery (DS)

- SaveButton & X Button will Show-Up (Visible)

- Edit Data inside TextInput

- The selected record will be highlighted with color (e,g. here: LightYellow)




UpdateContext({AddPopUp: true, EquipMLH: 602, EquipMLY: 166}); UpdateContext({EditEquipMaster: Defaults(TableMMD)})


Click On: Add Icon

- SaveButton & X Button will Show-Up (Visible)

- Add Data inside TextInput


SaveButton.OnSelect: [Red Font: Saving Formula; Can be Replaced with SubmitForm & other saving method]

Patch(TableMMD, EditEquipMaster, {No: If(!IsBlank(TableMMD.No), EditEquipMaster.No, Text(Max(TableMMD, No) + 1)), Serial_No: TextInput3_14.Text, Controlled_No: TextInput3_15.Text, Equipment_Name: Proper(TextInput3_21.Text), Brand: Proper(TextInput3_22.Text), Manufacturer: Proper(TextInput3_23.Text), Model_No: TextInput3_24.Text, Location: Proper(TextInput3_25.Text)}); UpdateContext({AddPopUp: false, EquipMLH: 664, EquipMLY: 104})


UpdateContext({AddPopUp: false, EquipMLH: 664, EquipMLY: 104})

Final Thought


PowerApps is the perfect tools in creating ERP / Productivity Program in manufacturing. Combination with Mobile Apps to expedite workaround input will expedite the whole data capturing and data analysis process.


Challenge Point....

- DeleteButton: may interested parties add a DeleteButton (next to Save Button and Cancel Button) with formula to deleted selected record.


Really love the idea of a single page app that efficiently does all CRUD operations! Bravo!

Hi Audrie, really glad to have your appreciation and I wish other readers can continue to take the challenge by adding DELETE button.

Have a nice day.

Thanks a ton @hpkeong - I was tinkering building my own CRUD based applications and having easily viewable information like this really helps the learning curve!

Hi @jarrystowe


You ae most welcome.

I am sorry that I should not have "Challange Point..." for DELEE function after advice from Audrie.

Anyway, once you had problem with DELETE function, do let me know.

It is a trick but quite easy.




For several days, I tried to build an application which enables users to view and edit a data in a single page but I couldn't.

This is very helpful.Great!Smiley Happy


Hi @Anonymous @jarrystowe @Audrie-MSFT


Thanks and appreciate your reference to my blog.


As pointed out and advice from @Audrie-MSFT, I should have complete explanation instead of giving challanges..


Here it is:


Save Button & Cancel (X) Button are stand-alone, but Delete Button must be bound to the database.

So, here it is.the Delete Function


Add a Gallery, have the Items set to:

- Gallery.Items = Table(EditEquipMaster)

- Gallery.Visible = AddPopUp


Insert a DELETE button or Trash Icon or anything you wish and set

- Button.OnSelect = Remove(TableMMD, ThisItem)



- When you click inside "Data Gallery, "+" button", all of them (Delete, Save & X) will pop-up

- In this case, Delete Button will be append the selected record into "Delete Gallery - but invisible" (This is what I mean as a trick to create Delete to make it look better) - Table(EditEquipMaster)

- So, when you click on any record, you can EDIT and also DEELTE with Remove(TableMMD, ThisItem).


So it is dynamics and you don;t have to navigate different scressn nor hassle in select and unselect different records to delete.


I hope this is my reply to my own question in the nlog.



If you are wish to have second thought before deleting, you can have extra action:

-  Set the *Gallery.Visible = AddPopUp1 (different visible variable)

- Modify the Gallery to have extra Cancel / Back Button inside the same area, with

Button.OnSelect = UpdateContext({AddPopUp1: false, EquipMLH: 664, EquipMLY: 104})


Insert another independent Delete Button / Icon / Trash next to the Save & X, and

- Set the Button.OnSelect = UpdateContext({AddPopUp1: true})


(Make sure to move the * Gallery to a better location to avoid overlapping)
