What's the diffent between ScrollIntoView(object item, ScrollIntoViewAlignment alignment) and ScrollIntoView(object item)

Question

Hello All.

When I use ScrollIntoView(object item), the parameter 'item' can be 'null'.

But when I use the ScrollIntoView(object item, ScrollIntoViewAlignment alignment),  the parameter 'item' can't be 'null'.

Why is that?

Answer 1

Hi Shirley,

Think of the following scenario, if you set "item" as "null" in ScrollIntoView(object item, ScrollIntoViewAlignment alignment), then which item can be applied with ScrollIntoViewAlignment?

Best Regards,

--James

Answer 2

Nothing....,

I thought ScrollIntoViewAlignment would be used to the first item.

I just want to know if it has other thing to be noted when I use  ScrollIntoView(object item, ScrollIntoViewAlignment alignment), I'm affraid to miss something.
