DataGridView的单元格中键入 [英] DataGridView cells type

问题描述

我有一个复选框列的DataGridView，但我想，一些列细胞是文本框细胞。结果，是否有可能具有多个小区类型中的一列？ ？如果是的话，那么怎么

I have datagridview with checkbox column, but I want, that some of the columns cells are textbox cells.
Is it possible to have multiple cells types in one column? If yes, then how?

推荐答案

这里有两种方法可以做到这一点：

There're two ways to do this:

1. 蒙上了的DataGridViewCell 来存在一定的细胞类型。例如，将一个 DataGridViewTextBoxCell 到的DataGridViewComboBoxCell 键入


2. 创建一个控制并把它添加到 DataGridView的，设置它的位置和大小的控件集合以适应单元格，要成为主持人。

1. Cast a DataGridViewCell to a certain cell type that exists. For example, convert a DataGridViewTextBoxCell to DataGridViewComboBoxCell type.
2. Create a control and add it into the controls collection of DataGridView, set its location and size to fit the cell that to be host.

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;
}

从的这里。
