Hi @PowerApps11 :

Do you want to update the value of 'glbCustomers' when user select a new address on the dropdown?

If so,you could set the dorpdown's OnChange property to:

Set(glbCustomers,Self.Selected.Addresss)

Best Regards,

Bof

Hi @v-bofeng-msft
Sorry for delay for replaying but is not what I wanted , some reason someone accepted and close the post ?
let me explain my intension normally if I need to get an particular details like address of an user to searched from the main list against an text input like I have a joe jones, need to get his address I need to do lookup from the user list Lookup(Userlist,Name= txtUserbocx.text ).Address, which will give me the address, but I would like to minimize the calls to the database and add on AppStart so I run only one time like an Variable, please correct me if am wrong
so now on the form how can i use that variable to reuse within the app
Thank you

Hi @PowerApps11 ,

Instead of creating variable, you can go with Collection. So on start you can collect your data as below-

ClearCollect(glbCustomers,Customers.Addresss)
Now you can use this collection in your form on any screen. You can do lookup, apply filter as well.

Good Luck!

Hi @PowerApps11 ,

Same as you mentioned in your reply
Lookup(Userlist,Name= txtUserbocx.text )
Instead of UserList, use collection name.
