Handling Dialog Submissions

Dialogs have a specific dialog_submit event to handle submissions. When a user submits a form inside a dialog, the app is notified via this event, which is then handled to process the submission values, and can either send a response or proceed to more steps in the dialogs (see Multi-step Dialogs).

In this example, we show how to handle dialog submissions from an Adaptive Card form:

@app.on_dialog_submit
async def handle_dialog_submit(ctx: ActivityContext[TaskSubmitInvokeActivity]):
    """Handle dialog submit events for all dialog types."""
    data: Optional[Any] = ctx.activity.value.data
    dialog_type = data.get("submissiondialogtype") if data else None

    if dialog_type == "simple_form":
        name = data.get("name") if data else None
        await ctx.send(f"Hi {name}, thanks for submitting the form!")
        return TaskModuleResponse(task=TaskModuleMessageResponse(value="Form was submitted"))

Similarly, handling dialog submissions from rendered webpages is also possible:

@app.on_dialog_submit
async def handle_dialog_submit(ctx: ActivityContext[TaskSubmitInvokeActivity]):
    """Handle dialog submit events for all dialog types."""
    data: Optional[Any] = ctx.activity.value.data
    dialog_type = data.get("submissiondialogtype") if data else None

    if dialog_type == "webpage_dialog":
        name = data.get("name") if data else None
        email = data.get("email") if data else None
        await ctx.send(f"Hi {name}, thanks for submitting the form! We got that your email is {email}")
        return InvokeResponse(
            body=TaskModuleResponse(task=TaskModuleMessageResponse(value="Form submitted successfully"))
        )
