向 Winforms DataGridView 添加按钮 [英] Adding a button to a Winforms DataGridView

问题描述

有没有办法在 C# 中向 Winforms DataGridView 单元格添加控件(例如按钮)?

Is there a way to add a control (e.g. a button) to a Winforms DataGridView cell in C#?

(我的目标是在网格的不同单元格中放置各种控件...)

(What I'm aiming at is putting various kinds of controls in different cells of the grid...)

推荐答案

你可以这样做....

有两种方法可以做到这一点:

There're two ways to do this:

• 1).将 DataGridViewCell 转换为存在的特定单元格类型.为了例如，将 DataGridViewTextBoxCell 转换为DataGridViewComboBoxCell 类型.
• 2).创建一个控件并将其添加到控件的集合中DataGridView，设置其位置和大小以适合要显示的单元格主持人.

请参阅下面的示例代码，其中说明了这些技巧.

See my sample code below which illustrates the tricks.

代码片段

    private void Form5_Load(object sender, EventArgs e)
    {
        DataTable dt = new DataTable();
        dt.Columns.Add("name");
        for (int j = 0; j < 10; j++)
        {
            dt.Rows.Add("");
        }
        this.dataGridView1.DataSource = dt;
        this.dataGridView1.Columns[0].Width = 200;

        /*
         * First method : Convert to an existed cell type such ComboBox cell,etc
         */

        DataGridViewComboBoxCell ComboBoxCell = new DataGridViewComboBoxCell();
        ComboBoxCell.Items.AddRange(new string[] { "aaa","bbb","ccc" });
        this.dataGridView1[0, 0] = ComboBoxCell;
        this.dataGridView1[0, 0].Value = "bbb";

        DataGridViewTextBoxCell TextBoxCell = new DataGridViewTextBoxCell();
        this.dataGridView1[0, 1] = TextBoxCell;
        this.dataGridView1[0, 1].Value = "some text";

        DataGridViewCheckBoxCell CheckBoxCell = new DataGridViewCheckBoxCell();
        CheckBoxCell.Style.Alignment = DataGridViewContentAlignment.MiddleCenter;
        this.dataGridView1[0, 2] = CheckBoxCell;
        this.dataGridView1[0, 2].Value = true;

        /*
         * Second method : Add control to the host in the cell
         */
        DateTimePicker dtp = new DateTimePicker();
        dtp.Value = DateTime.Now.AddDays(-10);
        //add DateTimePicker into the control collection of the DataGridView
        this.dataGridView1.Controls.Add(dtp);
        //set its location and size to fit the cell
        dtp.Location = this.dataGridView1.GetCellDisplayRectangle(0, 3,true).Location;
        dtp.Size = this.dataGridView1.GetCellDisplayRectangle(0, 3,true).Size;
    }
