DataGridView选择了单元格样式

Question

如何更改DataGridView（winforms）上的“选择样式”？

Answer 1

You can easily change the forecolor and backcolor of selcted cells by assigning values to the SelectedBackColor and SelectedForeColor of the Grid's DefaultCellStyle.

If you need to do any further styling you you need to handle the SelectionChanged event

Edit: (Other code sample had errors, adjusting for multiple selected cells [as in fullrowselect])

using System.Drawing.Font;

private void dataGridView_SelectionChanged(object sender, EventArgs e)
        {

            foreach(DataGridViewCell cell in ((DataGridView)sender).SelectedCells)
        {
            cell.Style = new DataGridViewCellStyle()
            {
                BackColor = Color.White,
                Font = new Font("Tahoma", 8F),
                ForeColor = SystemColors.WindowText,
                SelectionBackColor = Color.Red,
                SelectionForeColor = SystemColors.HighlightText
            };
        }
        }

Answer 2

使用GridView的SelectedCells属性和DataGridViewCell的Style属性 。

Answer 3

Handle the SelectionChanged event on your DataGridView and add code that looks something like this:

    private void dataGridView1_SelectionChanged(object sender, EventArgs e)
    {
        foreach (DataGridViewRow row in this.dataGridView1.Rows)
        {
            foreach (DataGridViewCell c in row.Cells)
            {
                c.Style = this.dataGridView1.DefaultCellStyle;
            }
        }


        DataGridViewCellStyle style = new DataGridViewCellStyle();
        style.BackColor = Color.Red;
        style.Font = new Font("Courier New", 14.4f, FontStyle.Bold);
        foreach (DataGridViewCell cell in this.dataGridView1.SelectedCells)
        {
            cell.Style = style;
        } 
    }

With this you can even draw a colored border to the selected cells.

private void dataGridView_CellPainting(object sender, DataGridViewCellPaintingEventArgs e)
{
    if (e.RowIndex >= 0 && e.ColumnIndex >= 0)
    {
        if (dataGridView.Rows[e.RowIndex].Cells[e.ColumnIndex].Selected == true)
        {
            e.Paint(e.CellBounds, DataGridViewPaintParts.All & ~DataGridViewPaintParts.Border);
            using (Pen p = new Pen(Color.Red, 1))
            {
                Rectangle rect = e.CellBounds;
                rect.Width -= 2;
                rect.Height -= 2;
                e.Graphics.DrawRectangle(p, rect);
            }
            e.Handled = true;
        }
    }
}
