在datagridview中使用按钮的字段 [英] Field with a button in the datagridview

问题描述

我有一个有界的Da​​taGridView。如何在一个字段中添加数据按钮？我将附上我如何看待它的屏幕截图 https://ibb.co/gjQi8H 。你有什么建议吗？



我尝试过：



它是WinForms，我认为我需要编写一个自定义列类型。

  class  TextAndButtonControl：UserControl 
 {
  private  TextBox textbox1; 
  private 按钮button1; 
 
  public  TextAndButtonControl（）
 {
  this  .textbox1 =  new  TextBox（）; 
  this  .Controls.Add（ this  .textbox1）; 
  this  .button1 =  new  Button（）; 
  this  .Controls.Add（ this  .button1）; 
  this  .RenderControl（）; 
  this  .button1.Click + =  new  EventHandler（button1_Click）; 
} 
 
  void  button1_Click（ object  sender，EventArgs e） 
 {
 MessageBox.Show（ 嗨）; 
} 
 
  public   string 文字
 {
 获取 {返回 此。 textbox1.Text; } 
  set  { this  .textbox1.Text = 值; } 
} 
 
  public   string  ButtonText 
 { 
 获取 {返回 此 .button1.Text; } 
  set  { this  .button1.Text = 值; } 
} 
 
  public   void  RenderControl（）
 {
  this  .textbox1.Location =  new  Point（ 0 ， 0 ）; 
 此 .textbox1.Width =  2  * 这 .Width /  3 ; 
 此 .textbox1.Height = 此 .Height; 
  this  .button1.Location =  new  Point（ 2  * 此 .Width /  3 ， 0 ）; 
 此 .button1.Width = 此 .Width /  3 ; 
  this  .button1.Height =  this  .Height; 
} 
} 

然后以主要形式：

  private   void  Form1_Load（ object  sender，EventArgs e）
 {
 TextAndButtonControl bcol =  new  TextAndButtonControl（）; 
 bcol.Text =  按钮列; 
 bcol.ButtonText =  点击我; 
 bcol.Name =   btnClickMe; 
 bcol.RenderControl（）; 
 dgMainGrid.Controls.Add（bcol）; 
}

请在此处查看答案：在C＃Windows应用程序中向DataGridView添加命令按钮 [ ^ ]

如果您只想让按钮出现在活动单元格中，您将不得不做一些自定义单元格绘制我害怕，请参阅： DataGridView.CellPainting事件（System.Windows.Forms） [ ^ ]

另一种方式可能是这样做ComboBox示例： DataGridView.CellPainting事件（System.Windows.Forms） [ ^

I have a bounded DataGridView. How can I add a button in one field with data? I will attach a screenshot of how I see it https://ibb.co/gjQi8H. Do you have any recommendations on this?

What I have tried:

it's WinForms and I think that I need to write a custom column type.

class TextAndButtonControl : UserControl
{
   private TextBox textbox1;
   private Button button1;

   public TextAndButtonControl()
   {
       this.textbox1 = new TextBox();
       this.Controls.Add(this.textbox1);
       this.button1 = new Button();
       this.Controls.Add(this.button1);
       this.RenderControl();
       this.button1.Click += new EventHandler(button1_Click);
   }

   void button1_Click(object sender, EventArgs e)
   {
       MessageBox.Show("Hi");
   }

   public string Text
   {
       get { return this.textbox1.Text; }
       set { this.textbox1.Text = value; }
   }

   public string ButtonText
   {
       get { return this.button1.Text; }
       set { this.button1.Text = value; }
   }

   public void RenderControl()
   {
       this.textbox1.Location = new Point(0, 0);
       this.textbox1.Width = 2 * this.Width / 3;
       this.textbox1.Height = this.Height;
       this.button1.Location = new Point(2 * this.Width / 3, 0);
       this.button1.Width = this.Width / 3;
       this.button1.Height = this.Height;
    }
}

Then in main form:

private void Form1_Load(object sender, EventArgs e)
{
    TextAndButtonControl bcol = new TextAndButtonControl();
    bcol.Text = "Button Column ";
    bcol.ButtonText = "Click Me";
    bcol.Name = "btnClickMe";
    bcol.RenderControl();
    dgMainGrid.Controls.Add(bcol);
}

But I'm getting: https://ibb.co/dgTaNc

See the answer here: Add Command Button to DataGridView in C# Windows Application[^]
If you only want the button to appear in the active cell, you will have to do some custom cell painting I'm afraid, see: DataGridView.CellPainting Event (System.Windows.Forms)[^]
Another way might be doing it like in this ComboBox example: DataGridView.CellPainting Event (System.Windows.Forms)[^]
