POPrevent LongListMultiSelector from "auto scrolling" when inserting items at the beginning
text
Body
copied!<p>I am using a LongListMultiSelector to show messages. Newest messages are at the botton - like in a messenger. I know have a button in the ListHeaderTemplate, that allows me to load earlier messages and insert them at the top at the list (<code>ObservableCollection.Insert(0, item);</code>).</p> <p>Inserting works, but it looks like that the list scrolls automatically to the last inserted item - it actually does not scroll, but it feels like it scrolls, because after the insert, the new item is displayed, but i rather looking for a solution that keeps the item visible that was the first before the new items where inserted and that i have to do another vertical scroll to the new top to reach the list header again.</p> <p>Any clues?</p> <p><em>EDIT 1</em></p> <p>consider, <code>oldFirstItem</code> is the current first item, then I insert a new item in front of the item. now the new item, becomes the first item, and since the scroll position does not change, the new item is visible: it feels like the list scrolls to the new inserted item, but it only pushed items 1 to n down. what i want is, that it pushes all new items up - into the area that the user does not see - and <code>oldFirstItem</code> at the top of the items that are visble. using ScrollTo makes that list jump.</p> <p><em>EDIT 2</em> I added a picture trying to show what I want to achieve. The area above the red line is not visible.<img src="https://i.stack.imgur.com/bv9st.png" alt="enter image description here"></p>
