C# 如何仅绘制DataGridView';s单元格背景不是它的内容?
我只需要画DataGridView单元格的背景,而不是它的内容。但当我画它的时候,也要画它的内容。请帮助我 我的代码是这样的C# 如何仅绘制DataGridView';s单元格背景不是它的内容?,c#,datagridview,C#,Datagridview,我只需要画DataGridView单元格的背景,而不是它的内容。但当我画它的时候,也要画它的内容。请帮助我 我的代码是这样的 private void Daywisegrid_CellPainting(object sender, DataGridViewCellPaintingEventArgs e) { if (e.RowIndex == 0 ) { using (Brush gridBrush
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;
}
}
}
}
我不知道为什么你需要捕捉细胞绘画事件来改变细胞背景颜色,就这样做吧
Daywisegrid.Rows[RowIndex].Cells[columnIndex].Style.BackColor = Color.Red;
但如果你想在绘画中做到这一点,试试这个
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;
}
}
}
}
应该是
e.Graphics.DrawLine(gridLinePen, e.CellBounds.Left, e.CellBounds.Bottom-1 , e.CellBounds.Right - 1, e.CellBounds.Bottom - 1);
e.CellBounds.Right,e.CellBounds.Bottom-1
点将被下一个单元格擦除
