DataGridView put text in ColumnHeader of RowHeader

问题:

Is it possible to add text into ColumnHeader of the RowHeader. I put autoincrement into Rowheaders of my DataGridView and I would like to put "No." above that.

Something like:

//Autoincrement RowHeaders
foreach (DataGridViewRow row in myDGV.Rows)
{
    row.HeaderCell.Value = String.Format("{0}", row.Index + 1);
}

No. | myColumn 1 | myColumn 2

1   | myText     | myText
2   | myText     | myText

//the "No." column are actually RowHeaders

回答1:

So basically you need to display "No." in top left corner?

That area is called TopLeftHeaderCell. It is just like the other DataGridViewCell, you can set its Value property to achieve the task.

dataGridView.TopLeftHeaderCell.Value = "No.";
