Rich ListView 4是一个完全基于.NET的ListView控件，也是目前为止市面上功能最强大的.NET ListView开发工具。与当前业界大部分的ListView工具都专注于基于网格的或者数据库的应用程序不同，Rich ListView则主要关注于更轻量级，更高性能以及功能丰富的解决方案。Rich ListView4是您的windows窗体应用程序的绝佳解决方案。

Rich ListView并非仅仅是Richer一个产品，也是我们用户的。我们的用户都知道，我们认真的获取使用反馈。从软件的实作之日起我们即认真获取用户的功能请求（我们将向用户发送使用的.dll程序但是在正式发布前将进行完备的测试）。到目前为止，该产品已经投入市场6年时间了，这意味着我们能获得更多的用户反馈以及进行更多的改进，以使得该软件更加优秀。

Rich ListView4提供了所有用户对于ListView的能想到的功能，所有的基础功能：包括自定义颜色，字体，标签以及其他诸如控制宽度，通过行设置，甚至通过子条目设置等。

特征综述

控件特征 完全的列自定义宽度以及重绘（并非单一的线性移动） 行和列跟踪 根线（请勿在拥有10k以上的节点的列表中使用该选项） 自定义网格设置（颜色，宽度，线的样式） 极其快速，可处理100k以上的节点 列分解 自动换行 自动调整行高 标题垂直对齐 自定义字体 控制宽度 行 子条目 自定义颜色 控制宽度 行 子条目 激活的嵌入功能 内置的网格中的编辑 内置的日期时间编辑 内置的复选框

性能

　　Rich ListView 4已经为性能经过了大量调整。无论是一次性添加大批量的条目还是升级大容量数据集，其都能轻松满足即使最苛刻的需求。

　　当前大多数网格和树列表都是面向数据库的，因此在显示大批量数据的时候都变现不佳。Rich ListView 4通过其极高的性能的.Net控件（无ActiveX控件或非托管代码）来尝试改变这种状况

　　右边的第一个视频显示的是ListView加载100k的网格（两列50k行），其加载时间仅为1秒钟。而Microsoft TreeView加载同样的数据则需要一个多小时。

　　右边的第二个视频显示的是带1000行和12列的ListView（12000个网格）每秒更新30次。是的，你没看错，确实是每秒更新30次！！！你可以试试用Microsoft的与我们的软件对比。

　　用户无需像使用Microsoft的控件一样，使用bug多多的虚拟列表以维持控件的高性能，其即可快速的运转。ListView还附带了一些样例程序，以展示该demo是如何执行的。

控件嵌入

嵌入式日历和进度条

　　控件嵌入是Rich ListView控件的一项很强大的功能。在该软件内部有大量内置插件，可以使得软件内嵌更简单，当然，用户也可通过手动重写代码的方法用其他方式自定义控件。在Rich ListView中，内嵌往往是基于列进行的，每一列均可嵌入不同的控件（或者不嵌入），（这也意味着一列中控件将无法影响到另一列）其有两个属性可对嵌入的控件进行管理：EmbeddedControlType和EmbeddedDisplayConditions。

　　可内置在网格中的编辑控件种类有文本框，复选框以及时间和日期选择器。用户也可以选择“UserType”，然后为之添加自己选定的激活的嵌入控件。

自定义绘制例子

　　为了能进行完全的网格编辑，用户也可以选择预先编辑和发布需要编辑的事件，只要控件在列表中被激活，即可联机加载预设值和自定义的内容。

自定义绘制

　　Richer控件系列的自定义绘制功能使得用户可以对绘制过程的每一部分进行自定义。自定义绘制不但对提供给用户的绘制功能进行了扩展，而且用户还可以进行发布和预绘制，以将之添加至已经绘在控件表面上。

　　用户可以查看控件安装时随带的自定义绘制样例，以便了解其可以进行何种程度的自定义绘制。这是我们软件最受欢迎的功能之一，用户可自由的根据自己的想象的极限对控件进行定制。

强大的排序功能

　　我们的创造性的分类排序功能，功能强大且完全可以自定义。用户可以在 Rich ListView中使用我们内置的分类机制或者使用用户自己的，其即可满足用户的所有分类需求。Rich ListView支持稳定以及不定排序。

　　用户可以通过使用Sort属性查看在 Rich ListView中列是如何进行分类的。 Rich ListView的分类功能是基于每一列的，允许用户定义多个分类。分类包括两个方面：分类方式（用于分类的算法）和比较器类型（分类基于的方式）。

Rich ListView is a product not just of Richer but of our customers. As all our customers know, we take feedback seriously here. We have had feature requests that have been implemented that very day (we will send you the beta dll but you have to wait for full testing to get release). This control has been out for 6 years now which means a lot of hard work and customer feedback have gone into making this control the best it can be.

Rich ListView 4 comes with all the features you would expect in a ListView. All of the basic abilities including Custom Colors, Fonts, Tags, and more can be set Control Wide, by Rows or even by Sub Items!

Features Overview

Control Features Full column resize redraw (not single line movement) Hot tracking for rows and/or columns Root Lines (don't use this option on lists with 10k+ nodes) Custom grid settings (color, width, line style) Extremely fast, can handle 100k+ nodes. Column Spanning Word Wrap Auto Height Vertical Headers Custom fonts Controlwide Rows SubItems Custom colors Controlwide Rows SubItems Activated Embedding Built in cell edit functionality Built in DateTime edit Built in ComboBox

Performance

Rich ListView 4 is heavily tuned for performance. Whether adding large numbers of items or updating huge sets of data at a time, Rich ListView 4 can easily handle even the most demanding needs. Most grids and ListViews today are heavily DB oriented and tend to perform poorly when presented with large amounts of data. Rich ListView 4 attempts to fill this gap by providing an extremely high performance .Net control (no ActiveX or unmanaged code). The first video to the right shows the ListView being loaded with 100k cells (2 columns of 50k rows). The ListView loads in just over 1 second.  The Microsoft ListView would take upwards of an hour to load that many. The second video to the right shows the ListView with 1000 rows and 12 columns (12000 cells) updating 30 times a second. Yes, every single cell is updating 30 times a second. Let's see you try that with Microsoft or our competitors offerings! You don't need to use buggy virtual lists to support the high performance of this control like you do with the Microsoft controls. They work this fast right out of the box. Included with the ListView are example programs that demonstrate exactly how this demo was performed.

Control Embedding

Control embedding is a powerful capability of the Rich ListView control. There are a variety of build-in types in Rich ListView that help make control embedding easier, although you can customize the controls in any way you want through manual overriding of the code. In Rich ListView, embedding is always based on the column; each column can have a different (or no) control embedded. (This also means that the controls in one column cannot affect another column!) There are two properties that manage the embedded controls: EmbeddedControlType and EmbeddedDisplayConditions. Built in cell edit types are Textbox, ComboBox, and DateTimePicker. You can also select the 'UserType' and add your own activated embedded controls! To give you maximum control over your cell editing, you can subscribe to pre edit and post edit events so that you can load presets or customizations on the fly as your control is being activated in the list.

Embedded Calendar and Progress Bars

Custom Drawing

Custom drawing in the Richer control series allows a user to customize nearly every part of the drawing experience. Custom drawing not only extends to replacing the drawing that is provided for you, but you can 'Post' or 'Pre' draw so that you can add to what has already been drawn onto the control surface.! Check out our custom drawing application example that installs with the control to see just how deeply you can go with the customization of the drawing. This has been one of our most popular features as you can literally customize this control as far as your imagination can take you.

Powerful Sorting

Out of the box, our sorting is powerful and fully customizable.  Use one of our built in sorting mechanisms or roll your own, Rich ListView can satisfy all of your sorting needs. Rich ListView also supports both stable and unstable sorting! You can set the way columns are ordered in a Rich ListView instance using the Sort properties. Sorting with Rich ListView is on a per-column basis, allowing you to have multiple sorts defined. There are two aspects to sorting: the sort type (the algorithm used to sort) and the comparer type (what the sort is based on).
