Adding a button to a Winforms DataGridView

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

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

I would add it in the designer and make a template field. Easy way to go and put anything you want in the datagridview

Example

<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>

you can do like this....

There're two ways to do this:

  • 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.

See my sample code below which illustrates the tricks.

Code Snippet

    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;
    }

The DataGridViewButtonColumn is a provided column type that contains a clickable button. You can add your own controls to the cells:

http://msdn.microsoft.com/en-us/library/7tas5c80.aspx

Bear in mind it isn't always trivial, but I have seen someone put an entire DataGridView into a cell - looked weird.

There are also other provided columns:

DataGridViewButtonColumn
DataGridViewCheckBoxColumn
DataGridViewComboBoxColumn
DataGridViewImageColumn
DataGridViewLinkColumn
DataGridViewTextBoxColumn

You can change these in the column editor in the designer in Visual Studio, or add them in code to the Columns collection.
