我想使用c#在Windows窗体中自定义我的datagridviews。我想要做的是用我创建的渐变绘制datagrid标头:
public void Colorear_Barra_abajo(object sender, PaintEventArgs e)
{
Rectangle r = new Rectangle(0,0, panel_Borde_abajo.Width, panel_Borde_abajo.Height);
if (r.Width > 0 && r.Height > 0)
{
Color c1 = Color.FromArgb(255, 54, 54, 54);
Color c2 = Color.FromArgb(255, 62, 62, 62);
Color c3 = Color.FromArgb(255, 98, 98, 98);
LinearGradientBrush br = new LinearGradientBrush(r, c1, c3, 90, true);
ColorBlend cb = new ColorBlend();
cb.Positions = new[] { 0, (float)0.5, 1 };
cb.Colors = new[] { c1, c2 , c3 };
br.InterpolationColors = cb;
// paint
e.Graphics.FillRectangle(br, r);
}
}
问题是datagridviews没有绘画事件,所以我不能使用它。有什么办法用渐变绘制标题吗?还是唯一的方法是选择一种背景色?
谢谢..
最佳答案
如果您的意思是Column Header
,是的。在CellPainting Event
private void dataGridView1_CellPainting(object sender, DataGridViewCellPaintingEventArgs e)
{
if (e.RowIndex == -1)
{
Color c1 = Color.FromArgb(255, 54, 54, 54);
Color c2 = Color.FromArgb(255, 62, 62, 62);
Color c3 = Color.FromArgb(255, 98, 98, 98);
LinearGradientBrush br = new LinearGradientBrush(e.CellBounds, c1, c3, 90, true);
ColorBlend cb = new ColorBlend();
cb.Positions = new[] { 0, (float)0.5, 1 };
cb.Colors = new[] { c1, c2, c3 };
br.InterpolationColors = cb;
e.Graphics.FillRectangle(br, e.CellBounds);
e.PaintContent(e.ClipBounds);
e.Handled = true;
}
}
