C# DataGridView Colspan

Question

I want to dynamically create a excel-like table with datagridview, but I want to have the option to set colspan to some columns.

The idea is just to display data, the user will not type anything, but it should be in table/spreadsheet look. If I cannot have datagridview with colspan is there any other type of table-like tool which has a colspan?

I other hand the columns will be created dynamically from database query result.

I'm using windows forms.

Any ideas?

You might take a look at the TableLayoutPanel Class, which has a TableLayoutPanel.SetColumnSpan Method.

Here's a code sample, which spans the one of the text boxes on 2 columns:

var dt = new DataTable();
dt.Columns.Add("Id");
dt.Columns.Add("Value1");
dt.Columns.Add("Value2");

dt.Rows.Add(1, "aa", "xx");
dt.Rows.Add(2, "bb","yy");
dt.Rows.Add(3, "cc", "zz");
tableLayoutPanel1.CellBorderStyle = TableLayoutPanelCellBorderStyle.Single;
tableLayoutPanel1.ColumnCount = 4;
tableLayoutPanel1.AutoSize = true;
for (int i = 0; i < dt.Columns.Count; i++)
{
    var l = new Label();
    l.Dock = DockStyle.Fill;
    l.Text = dt.Columns[i].ColumnName;
    tableLayoutPanel1.Controls.Add(l, i, 0);
}
var emptyLabel = new Label();
emptyLabel.Text = "Empty label";
tableLayoutPanel1.Controls.Add(emptyLabel, 4, 0);
for (int i = 0; i < dt.Rows.Count; i++)
{
    for (int j = 0; j < dt.Rows[i].ItemArray.Length; j++)
    {
        var tb = new TextBox();
        tb.Multiline = true;
        tb.Dock = DockStyle.Fill;
        tb.Text = dt.Rows[i][j].ToString();
        tableLayoutPanel1.Controls.Add(tb, j, i+1);
        if (i == 1 && j == 2)
            tableLayoutPanel1.SetColumnSpan(tb, 2);
    }
}
