C# datagridview.cellpaintting事件刷新问题
如何手动调用cellpaintting进行刷新呢?下面是一例,对datagridview的单元格进行重绘,因没有办法手动调用cellpaintting事件,所以,无法对单元格强制绘制,我试用invalidate()进行强行重绘,结果也不调用cellpaintting,而是调用onpaint.

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace DatagridviewTest
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();

}

private void Form1_Load(object sender, EventArgs e)
{
this.dataGridView1.Rows.Add(10);
}

private void dataGridView1_CellPainting(object sender, DataGridViewCellPaintingEventArgs e)
{
if (e.RowIndex != -1)
{
e.Graphics.DrawString(e.RowIndex .ToString (), e.CellStyle.Font, new SolidBrush(Color.Red), e.CellBounds);
e.PaintContent(e.CellBounds);
e.Handled = true;
}


}


}
}

[解决办法]
你可以用js重新写html代码
