问题描述
我只需要绘制 DataGridView 单元格的背景而不是它的内容.但是当我在绘制它时,它也绘制它的内容.请帮帮我.
i need to paint only background of DataGridView cell not its Content.But while i'm doing painting it paint its content too.Please help me out.
我的代码是这样的.
private void Daywisegrid_CellPainting(object sender, DataGridViewCellPaintingEventArgs e)
{
if (e.RowIndex == 0 )
{
using (Brush gridBrush = new SolidBrush(this.Daywisegrid.GridColor))
{
using (Brush backColorBrush = new SolidBrush(e.CellStyle.BackColor))
{
using (Pen gridLinePen = new Pen(gridBrush))
{
// Clear cell
e.Graphics.FillRectangle(backColorBrush, e.CellBounds);
//Bottom line drawing
e.Graphics.DrawLine(gridLinePen, e.CellBounds.Left, e.CellBounds.Bottom-1 , e.CellBounds.Right, e.CellBounds.Bottom-1);
e.Handled = true;
}
}
}
}
推荐答案
我不知道为什么你需要捕捉 CellPainting 事件来改变单元格背景颜色就这样做
i am not sure why you need to catch CellPainting event to change cell background color just do it like this
Daywisegrid.Rows[RowIndex].Cells[columnIndex].Style.BackColor = Color.Red;
但是如果你想在绘画中做到这一点,试试这个
But if you want to do it in painting try this
private void Daywisegrid_CellPainting(object sender, DataGridViewCellPaintingEventArgs e)
{
if (e.RowIndex == 0 )
{
using (Brush gridBrush = new SolidBrush(this.Daywisegrid.GridColor))
{
using (Brush backColorBrush = new SolidBrush(e.CellStyle.BackColor))
{
using (Pen gridLinePen = new Pen(gridBrush))
{
// Clear cell
e.Graphics.FillRectangle(backColorBrush, e.CellBounds);
//Bottom line drawing
e.Graphics.DrawLine(gridLinePen, e.CellBounds.Left, e.CellBounds.Bottom-1 , e.CellBounds.Right, e.CellBounds.Bottom-1);
// here you force paint of content
e.PaintContent( e.ClipBounds );
e.Handled = true;
}
}
}
}
