Hi Experts,
Could anybody please help me in how to set the clearing business card contents functionality.
I have created a canvas app for phone and I'm not able to clear the business card as well as the values retrieved from business card in each field.
I want to achieve something like "if a button is clicked, reset the business card as well as the contents" or once the lead is captured and saved successfully clear the power app field contents
Kindly guide
Best regards,
Sumaira

@Sumaira
Currently, the Business card doesn't support Reset function. please vote for this idea which is in plan.
However, as an alternative workaround for resetting the form content, use variable to pass the BusinessCardReader value, and show on the form. when you want to reset them, just set these variables to blank.
For example:
1. set OnChange property of BusinessCardReader1:

UpdateContext({VarName:BusinessCardReader1.FullName,VarPhone:BusinessCardReader1.BusinessPhone})

2. set Default property of text box in the form to Variables
3. set OnSelect property of Reset button:

UpdateContext({VarName:Blank(),VarPhone:Blank()})

Did you reset the businesscard reader control? Else, could you share a screenshot of the build with the tree view for the componenets?

But it didn't work for the fields which stored business card data
Nor the previously uploaded business card was cleared

Hello,

Are they added to a form? In which case create a button with onselect: reset(form_name)...

If not, I would use Reset(xxx) where xxx is the text input field name...

Hope it helps
