scrollviewer

I have a GridView with GridView.ItemsSource set to a collection that implements ISupportIncrementalLoading . By implementing this, I am aiming to improve load time and UI responsiveness by only loading items that are needed for display. The framework handles this for me and it works great. <GridView ItemsSource="{Binding Items}"> <GridView.ItemTemplate> <DataTemplate> <TextBlock Text="{Binding Text}"/> </DataTemplate> </GridView.ItemTemplate> </GridView> However , if I wrap the above XAML in a ScrollViewer like the following, the entire collection of Items loads as though the GridView is

Can anybody please explain to me why the MouseDown event is not reaching the ScrollViewer in this easy example? <Window x:Class="MouseDownTest.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="MainWindow" Height="350" Width="525"> <Grid> <ScrollViewer Name="scrollViewer" Background="Green" MouseDown="ScrollViewer_MouseDown" PreviewMouseDown="ScrollViewer_PreviewMouseDown"> <Canvas Name="canvas" Background="Beige" MouseDown="Canvas_MouseDown" PreviewMouseDown="Canvas_PreviewMouseDown"> </Canvas> <

The structure of my wpf application is like: <Scrollviewer> <Grid> <Scrollviewer> <DataGrid> My Goal is, if the DataGrid exceeds the height of the screen to use it's own Scrollviewer. At the Moment only the outside ScrollViewer is used and so i have to scroll the whole Grid. Can someone please tell me how to do this? Rachel You need to set a height on the inner ScrollViewer, otherwise it'll stretch as much as it needs based on it's content's size. <Window x:Name="RootWindow"> <ScrollViewer> <Grid Height="{Binding ElementName=RootWindow, Path=ActualHeight}"> <Grid.RowDefinitions> <RowDefinition

I am writing my custom WPF ItemsControl to display a list of item. The items are shown embedded inside a ScrollViewer: <Style TargetType="MyCustomItemsControl"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="MyCustomItemsControl"> <ScrollViewer x:Name="PART_MyScrollViewer" > <ItemsPresenter/> </ScrollViewer> </ControlTemplate> </Setter.Value> </Setter> </Style> I want to make sure that when I move the mouse into the control, a particular item (marked as selected) will be scrolled into the mouse position. In my OnMouseEnter method I am able to find the item but I don't

I have a ScrollViewer and in that I am showing the Vertical Scrollbar, Now on changing resolution of the system I want to get the width of the scrollbar. I went through One StackOverflow Post there they mention to check for SystemParameters.ScrollWidth Property but again I din find any help from their. Can anybody please help me to fix my issue. Any answer will be appreciated. I think SystemParameters.VerticalScrollBarWidth is what you are looking for. I am not sure if this is the correct answer. Every WPF control can be restyled so even the scrollbar. So SystemParameters

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 view is shown, the other one is hidden/disappeared. So I have defined two rows, both heights are set as

In the example below I have a ListBox with dozens of font names in it. I would have thought it would automatically have a vertical scrollbar on it so that you can select ANY font, not just the first ones in the list, but it doesn't. So I added a "ScrollViewer" and that puts a "scrollbar area" on the right but there is no scrollbar in the scrollbar area so that you can scroll (!). Why isn't a scrollbar automatic and how do I force it to have a scrollbar? <StackPanel Name="stack1"> <Grid> <Grid.RowDefinitions> <RowDefinition Height="2*"></RowDefinition> <RowDefinition Height="*"></RowDefinition>

I have a ScrollViewer in my WPF App, and I want it to have smooth/animated scrolling effect just like Firefox has (if you know what I am talking about). I tried to search over the internet, and the only thing I've found is this: How To Create An Animated ScrollViewer (or ListBox) in WPF It works pretty good, but I have one problem with it - it animates the scrolling effect but the ScrollViewer 's Thumb goes directly to the point pressed - I want it to be animated aswell How can I cause the ScrollViewer 's Thumb to be animated as well, or else is there a working control with the same properties

I have some paths drawn to the screen in wpf. The coordinates being used are quite small so they have been made to fill the screen with a view box. I am now trying to implement pan and zoom functionality. I would like to be able to zoom to wherever the mouse is in relation to the ui (i.e zoomed screen center is equal to mouse coordinates). The current outcome is that the center of the screen when zoomed is not reflective of the exact mouse position on the ui. If you want to see what is happening... Here is my current solution file . Or Heres some code: View Xaml <Grid Name="MasterGrid"
