DataGridView 中单元格显示不一样颜色方法

1、DataGridView 中添加CellPainting事件方法

2、在CellPainting函数内部进行重绘

代码如下：

private void dgvSteps_CellPainting(object sender, DataGridViewCellPaintingEventArgs e)

{

if (e.ColumnIndex > -1 && e.RowIndex >= 0)//要进行重绘的单元格

{

Graphics gpcEventArgs = e.Graphics;

Color clrBack = e.CellStyle.BackColor;

Font fntText = e.CellStyle.Font;//获取单元格字体

//先使用北京颜色重画一遍背景

gpcEventArgs.FillRectangle(new SolidBrush(clrBack), e.CellBounds);

//设置字体的颜色

Color oneFore = System.Drawing.Color.Black;

Color secFore = System.Drawing.Color.Red;

string strFirstLine = "黑色内容";

string strSecondLine = "红色内容";

Size sizText = TextRenderer.MeasureText(e.Graphics, strFirstLine, fntText);

int intX = e.CellBounds.Left + e.CellStyle.Padding.Left;

int intY = e.CellBounds.Top + e.CellStyle.Padding.Top;

int intWidth = e.CellBounds.Width - (e.CellStyle.Padding.Left + e.CellStyle.Padding.Right);

int intHeight = sizText.Height + (e.CellStyle.Padding.Top + e.CellStyle.Padding.Bottom);

//第一行

TextRenderer.DrawText(e.Graphics, strFirstLine, fntText, new Rectangle(intX, intY, intWidth, intHeight),

oneFore, TextFormatFlags.PreserveGraphicsClipping | TextFormatFlags.EndEllipsis);

//另起一行

intY = intY + intHeight - 1;

TextRenderer.DrawText(e.Graphics, strSecondLine, fntText, new Rectangle(intX, intY, intWidth, intHeight),

secFore, TextFormatFlags.PreserveGraphicsClipping | TextFormatFlags.EndEllipsis);

////在同一行后面画

//intX = sizText.Width - 1;//在这行后面添加

//if (intX < e.CellBounds.Width)//能够显示的时候才进行绘制

//{

// intWidth = e.CellBounds.Width - intX;

// TextRenderer.DrawText(e.Graphics, strSecondLine, fntText, new Rectangle(intX, intY, intWidth, intHeight),

// secFore, TextFormatFlags.PreserveGraphicsClipping | TextFormatFlags.EndEllipsis);

//}

e.Handled = true;

}

}
