scrollviewer

问题 Based on the link scrollviewer to scroll to textbox position I tried to resolve scrolling issue when keyboard is launched but there is a problem in landscape mode. Problem in using (App.Current as App).RootFrame.RenderTransform = new CompositeTransform(); in landscape mode. Above solution helped me to generate a behaviour similar to New Appointment page as in the default calendar app for windows phone 7.5. But this (App.Current as App).RootFrame.RenderTransform = new CompositeTransform();does

问题 Ok, so I am not that versed in the mighty WPF, but I attempted an interesting project to jump into it. I have made a simple RSS/ATOM feed viewer that pulls the HTML out of and RRS or ATOM feed and sticks it in a Browser control which is added to a stack panel... which is the content of a ScrollViewer. Whew. Anyways the problem is, I am doing this all in the code behind and have found that the ScrollViewer doesn't work, or isn't recognizing the size of the content, so there is no scrolling. I

问题 We are developing a touch application in WPF. Our ScrollViewers have the property PanningMode set to Both to enable swipe scrolling. This works fine when swiping in empty areas and even on CheckBox and ComboBox controls. However when swiping on a TextBox (hold the finger briefly on the textbox and move it up or down), the ScrollViewer doesn't scroll. Is there a way to enable swipe-scrolling on all controls and only focus them on tap? This behaviour can be reproduced with the following code:

问题 How do I get the width available for the children of a scroll viewer in XAML? Thanks. 回答1: There's no direct way of doing this that I know of, since WPF automatically passes the available space in to the child controls' Measure() function so that they size to fit the available space. Note that, by default, it passes in infinity for the vertical direction, since content can scroll forever vertically. You can change the visibility of the scroll bars in both the vertical and horizontal direction

问题 I'm developping a WPF touch application. I have a scrollviewer containing buttons. I want to scroll the display when I touch-drag the buttons, and call the button's command when I tap.

问题 Is there a way to create a ScrollViewer which only allows content to scroll vertically? The horizontal (width) must be constrained in the same manner as a StackPanel's width is constrained to its parent (when HorizontalAlignment=Stretch). I have a resizable window which contains content I want to allow to scroll vertically. The window contains a ScrollViewer. Inside there is a lot of TextBoxs (a data entry form). When I type lots of text in a TextBox, the control just keeps growing to the

问题 I would like to make a horizontal listbox that could be infinite scrolling (looping listbox/scrollviewer, or circular listbox/scrollviewer), means that when I scroll to its end, its would scroll over from beginning. I have tried to make the listbox horizontal, but it wouldn't scroll so I put it inside a scrollviewer to have it scroll horizontally. However it's not the listbox that scroll and I need them somehow to scroll over from beginning. This is what I have so far: private void

问题 I have a WPF UserControl (inside an ElementHost ) with a ScrollViewer that contains an ItemsControl . The HorizontalScrollbarVisibility is set to Auto , so if no scrolling is necessary, the ScrollBar gets hidden. My requirement is, that if the ScrollBar gets shown/hidden, the ElementHost does adjust it's height accordingly. To achieve that, I'm listening to the SizeChanged event, I get the DesiredSize of the ScrollViewer in the EventHandler , then I pass DesiredSize.Height to the ElementHost
