我有一个datagridview如下:
我想制作一个单元格datagridview的背景颜色大约20%,50%,...透明(不完全透明),背景中有一种颜色(即黑色,紫色,灰色,...... )?
我尝试了很多方法,但我无法做到:
private void CustomerDGV_CellContentClick(object sender, DataGridViewCellEventArgs e)
{
try
{
// Black 20%
if (e.ColumnIndex == 1)
{
SetCellsTransparent(e.RowIndex, Color.Black, 0.2);
}
// Purple 50%
if (e.ColumnIndex == 2)
{
SetCellsTransparent(e.RowIndex, Color.Purple, 0.5);
}
// Gray 100%
if (e.ColumnIndex == 3)
{
SetCellsTransparent(e.RowIndex, Color.Gray, 1);
}
}
catch (Exception) { }
}
public void SetCellsTransparent(int rowIdx, Color color, double transparency)
{
//Color color = ColorTranslator.FromHtml("#000000");
//Color color = Color.Red;
//this.Rows[rowIdx].Cells[0].Style.BackColor = color;
//this.Rows[rowIdx].Cells[0].Style.BackColor = Color.FromArgb(50, color);
var whiteness = 255 - Convert.ToInt32(transparency * 255);
this.Rows[rowIdx].Cells[0].Style.BackColor = Color.FromArgb(255, whiteness, whiteness); //Red
this.ClearSelection();
}
任何有关这些的提示都会有很大帮助。提前谢谢。
