问题
I want to show the tooltip on my scrollviewer on page scrolling which shows the current page number in it which i asked here- Tooltip on scrollviewer in documentviewer.
I have implemented the answer after making some changes in the proposed solution but i face some problem. If i write this in my scroll_changed event if (Mouse.LeftButton == MouseButtonState.Pressed) it works perfectly fine but if i have a deferred scrolling enabled on my custom document viewer, the popup(tooltip) never appears..:(
Is there any workaround for it??
