刚刚开始程序设计的码农生涯,也许一些开发工具上的控件可以满足我们的需求,但是随之时间的迁移,我们对控件的呈现形式需求越来越多样化,这个时候就需要我们来自定义控件,我是一个刚刚入职没多久的菜鸟,接触软件开发也没有超过两年的时间,在以前的日子里,开发工具上的控件基本可以达到我学习的目的。但是现在工作了,用户的需求多样化,也造就了我们程序员的鬼斧神手。
今天由于需求,我需要作出如下图这样的界面并绑定数据库数据,开始我有几个思路,并且一个一个去尝试,对于winform的这种格式,之前从来也没有做过,如果是asp.net这种格式的话就非常的简单了。
思路一:listview控件,看上去listview控件可以实现这种界面,但是由于界面的局限性,做出这种效果似乎不大可能,在尝试过一两天的时间后,我觉得绑定数据是没有任何问题的,但是,问题就是在listview控件中实现如下图这种格式的布局。所以我选择了放弃,不知道各位用listview控件实现过这种效果没有。后来听说重写listview的方法可行,但是我没有去试过。
思路二:datagridview控件,开始没有往这个方面去考虑,部门里大牛们说可以,我仔细的看了一下datagridview控件的一下属性,其中列的类型里面控件格式没有我需要的控件,可得的话,又要方法重写了。这个工作量估计很大,而且布局能不能布局成这样的效果我也不知道。这个我想了一下也没有去尝试。
思路三:自定义控件,以前在学校里面接触过自定义控件,但都是简单的拼接一下各个不同的控件,没有什么特别的功能,今天特意的学习了一下字典控件,最终做好了一个类似于IDE里面的控件一样可以轻松使用。
实现效果不再熬数,这里我记下我写过的代码:
using System.Data;
using System.Data.SqlClient;
namespace menu
{
partial class MyControl
{
/// <summary>
/// 清理所有正在使用的资源。
/// </summary>
/// <param name="disposing">如果应释放托管资源,为 true;否则为 false。</param>
protected override void Dispose(bool disposing)
{
if (disposing && (components != null))
{
components.Dispose();
}
base.Dispose(disposing);
}
