由 主宰稳场 提交于 2019-11-30 08:13:19
I have a TextBlock within a ScrollViewer that aligns with stretch to its window. I need the TextBlock to behave as the following: Resizes with window, no scrollbars When resized below a certain width the TextBlock needs to keep a MinWidth and scrollbars should appear TextWrapping or TextTrimming should work appropriately How can I get this functionality? I have tried several ways, involving bindings to ActualWidth & ActualHeight , but can't get it to work. This can't be that difficult, what am I missing? Here is a code sample to put in XamlPad (no MinWidth is set yet): <Window xmlns="http:/

How to make scrollviewer work with Height set to Auto in WPF?

由 风流意气都作罢 提交于 2019-11-30 06:57:15
问题 I have learned that if the height of a grid row, where the ScrollViewer resides, is set as Auto , the vertical scroll bar will not take effect since the actual size of the ScrollViewer can be larger than the height in sight. So in order to make the scroll bar work, I should set the height to either a fixed number or star height However, I now have this requirement, that I have two different views reside in two grid rows, and I have a toggle button to switch between these two views: when one

The Application I am building an application which includes a range selector. This consists of two custom drawn Slider controls contained within one UserControl derived class. The range selector control is then contained inside a ScrollViewer which has the HorizonalScrollBar visible most of the time. Sample Application Code: ( appologies for the wall of text ) Window.xaml ( the Window file ): <Grid> <ScrollViewer x:Name="ScrollViewer" HorizontalScrollBarVisibility="Visible" VerticalScrollBarVisibility="Disabled"> <local:SliderTest x:Name="slider" LowerValue="0" UpperValue="10" Minimum="0"

I am building a photo application, using a FlipView and a listView as a Pagination. When I click on the thumbnail picture in the ListView it shows me the same picture in the FlipView . And when I swipe into the FlipView , any photo selected will select the same picture in the ListView . This is done by adding to both of them: To the ListView : SelectedIndex="{Binding Path=SelectedIndex, ElementName=flipView1, Mode=TwoWay} And to the FlipView : SelectedIndex="{Binding Path=SelectedIndex, ElementName=listView1, Mode=TwoWay} And to the ListView SelectionChanged event I added: if (e.AddedItems

WPF ListView Always show complete items

由 懵懂的女人 提交于 2019-11-30 03:58:21
问题 I've got an app with multiple ListView controls where there's a requirement that the item's in the ListView must be fully visible. There should never be partial ListViewItem's showing in the list. If the user releases the ScrollViewer at a position that ends up showing a partial item, then the list should "snap" and correct itself so that only complete items are displayed. Has anyone done this before? I think I'm going to need to overload ListView and/or ScrollViewer to do this. I'm looking

How to place a ScrollViewer on top of the content it should scroll

由 混江龙づ霸主 提交于 2019-11-29 18:53:06
问题 I would like to put my ScrollViewer in such a way that it overlaps/sits on top of the content it scrolls. I would set the Opacity of the ScrollViewer so that the content is visible underneath.

EDIT: I understand that the ScrollViewer is a Decorator and that the content is not aware of the ScrollViewer. This
