simple button textbox quesiton

[tehdeadhand]

Hey im trying to have onbutton press take text from 2 textboes add them and display it into textbox 3.

i can do it in everyother language but power apps is baffling me.

something like in vb

 on button press

textbox3.text = textbox1.text + textbox2.text

or

var txtb1

var txtb2

txtb1 = textbox1.text

txtb2 = textbox2.text

textbox3.text = txtb1 + txtb2

i cant figure out how to get power apps to update a textbox from a button without assigning the textbox text to a dynamic variable.

Thank you

PowerApps doesn't provide a way to directly set the formulas for control properties, but you can achieve your desired behavior by using context variables:

button.onSelect = UpdateContext({textboxSum: textbox1.text + textbox2.text})

textbox3.text = textboxSum

Hi

Allowed me to share.

- Sum(TextInput1.Text, TextInput1_1.Text)

https://powerapps.microsoft.com/en-us/tutorials/function-aggregates/

You can use either:

- Sum( Table, NumericalFormula ), or

- Sum (value1, value2, value3, ...)

Is that what you want?

PowerApps can be quite straightforward instead of declaring either local variable or global variable as of other programming language.

Hope this helps.
