Disable a button with a condition

Posted on by Community Power Pla... Microsoft Employee

Hello,

I would like a button to be accessible only the first time the user visits and that he fills out the form and validate, once this is done the button should be disabled

To do this I would like to apply a condition: if the user has filled in the information, then logically we will find his name and we will be able to compare him with the connected user if we find his name the button is disabled otherwise he can access and enter the information.

example of what I want to do, but I have a mistake, probably 'patient'.

I hope I was understandable enough,

Thank you for your help

Hi @Anonymous ,
Is Patient a list or a field in a list?
Assuming it is a field, try the below - firstly at App OnStart to avoid Delegation issues
Set(vUserName,User().FullName)
Then your button DisplayMode
If( IsBlank( Lookup( YourSPListName, Patient=vUserName, Patient ( ), DisplayMode.Edit, DisplayMode.Disabled )

Please click Accept as solution if my post helped you solve your issue. This will help others find it more readily. It also closes the item. If the content was useful in other ways, please consider giving it Thumbs Up.

You’ll want to use LOOKUP to see if the user’s name is already in your datasource

If(IsBlank(LookUp(your_datasource_name, your_column_name=User().FullName)), DisplayMode.Edit, DisplayMode.Disabled)

Note: my solution assumes your column is single line text
