Answer 1

APS.net我知道，这个不太清楚，应该有事件触发的，你可以试试，看看哪个名字更像

Answer 2

private void dataGridView1_CellMouseEnter(object sender, DataGridViewCellEventArgs e)
{
   DataGridViewCellStyle newCellStyle = new DataGridViewCellStyle();
   newCellStyle.....;   dataGridView1.Rows[e.RowIndex].DefaultCellStyle = newCellStyle;
}

Answer 3

private void dataGridView1_CellMouseLeave(object sender,
    DataGridViewCellEventArgs e)
{  
if (e.ColumnIndex >= 0 & e.RowIndex >= 0) { 
        DataGridView dgv = (DataGridView)sender; 
        dgv(e.ColumnIndex, e.RowIndex).Style.BackColor = Color.Empty; 
        dgv(e.ColumnIndex, e.RowIndex).Style.SelectionBackColor = Color.Empty; 
    } 
}

Answer 4

呵呵，修改并补充一下就可以了：       private void dataGridView1_CellMouseLeave(object sender, DataGridViewCellEventArgs e)
        {
            if (e.ColumnIndex >= 0 & e.RowIndex >= 0)
            {
                DataGridView dgv = (DataGridView)sender;
                dgv[e.ColumnIndex, e.RowIndex].Style.BackColor = Color.Empty ;
                dgv[e.ColumnIndex, e.RowIndex].Style.SelectionBackColor = Color.Empty  ;
            } 
        }        private void dataGridView1_CellMouseEnter(object sender, DataGridViewCellEventArgs e)
        {
            if (e.ColumnIndex >= 0 & e.RowIndex >= 0)
            {
                DataGridView dgv = (DataGridView)sender;
                dgv[e.ColumnIndex, e.RowIndex].Style.BackColor = Color.Yellow;
                dgv[e.ColumnIndex, e.RowIndex].Style.SelectionBackColor = Color.Red;
            } 
        }

Answer 5

也可以这样：        private void dataGridView1_CellMouseLeave(object sender, DataGridViewCellEventArgs e)
        {
            if (e.ColumnIndex >= 0 & e.RowIndex >= 0)
            {
                this.dataGridView1[e.ColumnIndex, e.RowIndex].Style.BackColor = Color.Empty;
            }
        }        private void dataGridView1_CellMouseEnter(object sender, DataGridViewCellEventArgs e)
        {
            if (e.ColumnIndex >= 0 & e.RowIndex >= 0)
            {
                this.dataGridView1[e.ColumnIndex, e.RowIndex].Style.BackColor = Color.Red;
            }
        }

Answer 6

 //鼠标移开效果        
        private void dataGridView1_CellMouseLeave(object sender, DataGridViewCellEventArgs e)
        {
            if (e.ColumnIndex >= 0 & e.RowIndex >= 0)
            {
                for (int i = 0; i < dataGridView1.Columns.Count; i++)
                {
                    dataGridView1[i, e.RowIndex].Style.BackColor = Color.Empty;
                }
            }
        }
        
        //鼠标划过效果
        private void dataGridView1_CellMouseEnter(object sender, DataGridViewCellEventArgs e)
        {
            if (e.ColumnIndex >= 0 & e.RowIndex >= 0)
            {
                for (int i = 0; i < dataGridView1.Columns.Count; i++)
                {
                    dataGridView1[i, e.RowIndex].Style.BackColor = Color.FromArgb(255, 204, 102);
                }
            }
        }
