wrappanel

问题 I installed Windows 7 . I then installed Web Developer 2010 Express from here with the Web Platform Installer . I then installed the the April 15 release of Silverlight 4 Toolkit from here. I then added this reference : alt text http://www.deviantsart.com/upload/ijk0lm.png Then in my XAML, I reference it like this but it gives me no intellisense and tells me that I am missing an assembly reference : alt text http://www.deviantsart.com/upload/cd4vrj.png update: xmlns:tk="clr-namespace:System

问题 does anyone have a functioning virtualising WrapPanel I can use in a WPF application? I have downloaded and tried the implementation at http://virtualwrappanel.codeplex.com/. However, I get the following exception: "Layout measurement override of element 'MyNamespace.VirtualizingWrapPanel' should not return PositiveInfinity as its DesiredSize, even if Infinity is passed in as available size." This is when trying to apply the wrappanel to a ListBox 回答1: This is probably a bug that you might be

问题 I need to list items (all of same size) vertically (with a ScrollViewer). I want the items to spread through x columns if the container is large enough to display x columns I first tried that : <ScrollViewer> <toolkit:WrapPanel Orientation="Horizontal" ItemHeight="30" ItemWidth="100"> <Button Content="1" /> <Button Content="2" /> <Button Content="3" /> <Button Content="4" /> <Button Content="5" /> </toolkit:WrapPanel> </ScrollViewer> Result - The WrapPanel works like I want but my items are

问题 Does anyone know if it's even possible to enter a line break into a WPF Wrap panel? It goes against what the wrap panel is for, so I'm not sure if it's possible. And if it's not, is there any other WPF control that actually allows me to enter a line break into it and supports adding children (my own custom controls?) 回答1: This is a line break in a WrapPanel : <WrapPanel> <TextBlock Text=" "/> </WrapPanel> Update I think I figured out what you're trying to ask. If you have a WrapPanel that is

问题 I have implemented custom itempanel for gridview to support variable item height using this link posted by JerryNixon.My Custom panel supports 3 different sized template(depending on image dimension I am deciding which template to use).This custom Gridview should have pagination and it should support more than 200 items. Right now i could load only 50 items and it crashes because of out of memory exception event in 1GB device . Its one of the requirement in out project. I know when we

问题 Essentially I want a wrapPanel, but I would like items to snap to a grid rather than be pressed up to the left, so I can get a nice uniform looking grid, that automatically consumes available space. WrapPanel handles the resize part. WPF.Contrib.AutoGrid handles a nice automatic grid. Anyone got a control that combines them? My use case is I have a series of somewhat irregularly shaped controls. I would like them to appear in nice columns so the wrap panel should snap to the next "tabstop"

问题 I have an empty grid with no data but with all the columns in the XAML - is there way to create multiple of these grids in the code-behinds ie .cs file I know how to create new grids in the code-behind but not existing grids...any ideas? Thanks Ram 回答1: You can do that by making your "existing grid" a separate UserControl . First, you need to add a UserControl via [Add]->[User Control...]->[User Control (WPF)]. Next, put your "existing grid" inside the added UserControl .

问题 I have a class defined this way: public class CustomClass { string Name; int Age; Usercontrol usercontrol; } where Usercontrol is a visual element that I want to insert in a WrapPanel. CustomClass is organized in a static ObservableCollection. public static class CollectionClass { public static ObservableCollection<CustomClass> MyCollection = new ObservableCollection<CustomClass>(); } I am looking to bind the usercontrol property of the CustomClass in the collection to be visualized in the

问题 Normally a WPF WrapPanel (Orientation="Vertical") will stack items vertically (and grow vertically) until it runs out of space from the parent container, and then it will "wrap" to the next column. I want this functionality, but I want to add a hard limit to the number of items in a column. For instance, if my height is 100 and I have 3 items that are 30 pixels high, normally it could fit them all without wrapping. However, say I want to force it to wrap after 2. In that case, I want it to

问题 I need to configure a wrap panel where I can set the max rows or max columns in it. This is really necessary, I'm using WPF 4.0. But the another day, I was programmin Metro applications and I remember that one of its controls has this properties, but in WPF not (until I know). Is exists such control in WPF 4.0? Or do I need to create a new one? 回答1: You can set ItemHeight and ItemWidth properties to set the max rows and columns... For more info, have a look here 回答2: Here is an implementation
