dot net 2005 提供了datagridview 这个控件，但是总感觉不好使，尤其当想在datagridview中显示combobox,checkbox时，并把结果写到数据库时总是感觉不太方便，于是决定自己改写datagrid自己加入combobox,checkbox

我把两个类封装在XUIControls包中了，提供了XUIControl.dll供大家使用

下面说说如何 定制自己的datagrid风格

  一。 打开dot net(2005 or 2003 2005中好像找不到datagrid控件 需要自己new个

1. 文件--〉新建--〉项目 选择 visual c# |类库 文件名定义为XUIControls

2. 选中XUIControls 项目右键 添加新项 选择c# 类文件,命名DataGridComboBoxColumnStyle.cs(如果想定制checkbox,可以命名为DataGridCheckBoxColumnStyle.cs,其它类似)

3.打开DataGridComboBoxColumnStyle.cs文件 添加代码：

using System;
using System.ComponentModel;
using System.Collections.Generic;
using System.Diagnostics;
using System.Text;
using System.Windows.Forms;
using System.Drawing;

namespace XUIControls
{
    public partial class DataGridComboBoxColumnStyle : System.Windows.Forms.DataGridColumnStyle
    {

        private ComboBox X_ComboBox = new ComboBox();//define new component
        private bool IsEditing;                     

       public DataGridComboBoxColumnStyle(IContainer container)
        {
             container.Add(this);//add this component to container
             InitializeComponent();// initialize the component
        }

        //the default construct fuction
        public DataGridComboBoxColumnStyle(): base()
        {
            // TODO: Add constructor logic here
            X_ComboBox.Visible = false;// the default setting is unvisible
        }

        /* 备注
         当 DataGridColumnStyle 方法的 Commit 方法返回 false 时，Abort 方法被 DataGrid 使用。在这种情况  下，列值滚动回原先的值。
         在返回之前，DataGridColumnStyle 必须结束所有编辑操作。使用 Abort 方法来实现该操作。
         System.Windows.Forms.DataGrid 控件的 EndEdit 方法间接调用 Abort（如果其 ShouldAbort 参数设置为 true）。
        */
        protected override void Abort(int rowNum)
        {  // this method override the parent's method.
           //when it is invoked,it will originate an request to interrupt the edite.
            IsEditing = false;// set the component unedited.
            X_ComboBox.Click -= new EventHandler(this.ComboBoxValueChanged);//remove the dispose fuction
            Invalidate();//constrain or enforce the component repainted.
         }

         /*在派生类中被重写时，将启动一个请求来完成编辑过程。
         参数
          dataSource DataGridColumnStyle 的 CurrencyManager。
          rowNum     所编辑行的行号。
         返回值      如果编辑过程成功提交，则为 true；否则为 false。
         备注
                对继承者的说明:   Commit 方法应该由从 DataGridColumnStyle 类中派生的类使用以重设它们的编辑状态，例如，如果 DataGridColumnStyle 承载一个编辑控件，可以放弃焦点。请参见 ConcedeFocus 方法。

        }
    }
}

 

其实两个类的代码类似，如果你想添加其它的控件也可以用类似的方法，注意在 X_CheckBox.Click += new EventHandler(this.CheckedChanged); 添加自己欲使用的事件，并且在下面一定要定义这个处理函数

当然也可以添加其它函数，比如设置文本显示，大小，颜色风格等，传值。

4。接下来要做的就是生成.dll，因为没有main()所以是不能执行的，编译后会提示

警告 1 设计器必须创建类型“System.Windows.Forms.DataGridColumnStyle”的实例，但该类型已声明为抽象，因此设计器无法创建该类型的实例。  0 0 

这已经成功了，如果有别的错误，那就有问题了需要修改。

然后会在debug文件夹中找到 XUIControls.dll，以后就可以引用它了。

二。使用自定义风格的datagrid

//----------------------------------------------------------------------------------------------------------------------------------------------

1. new project->c# project->choose [the windows applications ]->projectname: NewDataGrid

then we have builded the new c# project  NewDataGrid 

next

2. open the project  and add a datagrid component to the panel. you may can't find it in dot net 2005 .

you have to new a datagrid and modify the designer to add it. if in dotnet2003 ,no problem.then next

3 .if you are in dot net2003 ,add a datagrid from the component panel to the workarea and

    skip to the next step.   when in dot net 2005,we must do :

    open the FROM1.DESIGNER.CS  (choose the FUn:InitializeComponent(),then skip to the definiton)

  add    " this.dataGrid1 = new System.Windows.Forms.DataGrid();"

             "((System.ComponentModel.ISupportInitialize)(this.dataGrid1)).BeginInit();"

    and   set the style:

            this.dataGrid1.CaptionText = "adsfsadfsadf";
            this.dataGrid1.DataMember = "";
            this.dataGrid1.HeaderForeColor = System.Drawing.SystemColors.ControlText;
            this.dataGrid1.Location = new System.Drawing.Point(12, 12);
            this.dataGrid1.Name = "dataGrid1";
            this.dataGrid1.Size = new System.Drawing.Size(407, 260);
            this.dataGrid1.TabIndex = 1; 

   and add the control-----

                                                     this.Controls.Add(this.dataGrid1);

                                                      ((System.ComponentModel.ISupportInitialize)(this.dataGrid1)).EndInit();

                   ----------- in the bottom in the function

now it's ok
