一列的DataGridView细胞不能有不同类型 [英] DataGridview cells of one column can't have different type

问题描述

以及我有一个DataGridView，和我有一个专栏，我想要做的就是控制单元在此列，有时使其组合框，有时textBox中....等

well I have a datagridview , and i have a column, all i want to do is controlling the cells in this column, sometimes make it combobox, sometimes textBox ....etc

我可以做一个列的单元格只有一种类型，我可以使许多细胞在一列中键入？

I can make the cells of a column have only one type , can i make many cells type in one column ?

希望这是显而易见的。

推荐答案

有两种方法可以做到这一点：

There are two ways to do this:

1. 蒙上了DataGridViewCell的到一个真实存在一定的细胞类型。例如，转换DataGridViewTextBoxCell到的DataGridViewComboBoxCell类型。


2. 创建一个控件并将其添加到DataGridView的控件集合，设置它的位置和大小以适应单元格，要成为主机。

请参阅我下面的代码示例，它说明的技巧。

See my sample code below which illustrates the tricks.

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;
        }
