有没有办法在C#的Winforms DataGridView单元格中添加控件(例如按钮)?
(我的目的是将各种类型的控件放置在网格的不同单元格中...)
(我的目的是将各种类型的控件放置在网格的不同单元格中...)
您可以像这样做...
有两种方法可以实现此目的:
请参见下面的示例代码,其中说明了这些技巧。
代码段
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;
}
DataGridViewButtonColumn
是一种提供的列类型,其中包含可点击的按钮。您可以将自己的控件添加到单元格中:

请记住,这并不总是简单的,但我曾经看到有人将整个DataGridView
放入一个单元格中——看起来很奇怪。DataGridViewButtonColumn
DataGridViewCheckBoxColumn
DataGridViewComboBoxColumn
DataGridViewImageColumn
DataGridViewLinkColumn
DataGridViewTextBoxColumn
我会在设计器中添加它,并创建一个模板字段。这是一个简单的方法,可以将任何你想要的东西放入 datagridview。
示例
<asp:DataGrid ID="somedatagrid" runat="server">
<Columns>
<asp:TemplateColumn>
<ItemTemplate>
<asp:Button ID="somebutton" runat="server" Text="some button" />
</ItemTemplate>
</asp:TemplateColumn>
</Columns>
</asp:DataGrid>
