我有一个datagridview,我有一个列,我想做的就是控制这个列中的单元格,有时候使它成为组合框,有时候是textBox ....等等。
我可以让列的单元格只有一种类型,我可以在一列中输入多个单元格吗?
希望很清楚。答案 0 :(得分:7)
有两种方法可以做到这一点:
请参阅下面的示例代码,其中说明了这些技巧。
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;
}
