(DataGridView + Binding)如何根据绑定的对象来着色线？

Question

我想根据绑定对象的属性为特定行添加背景颜色.

我有(并且它有效)的解决方案是使用事件,DataBindingComplete但我不认为这是最好的解决方案.

这是事件:

    private void myGrid_DataBindingComplete(object sender, DataGridViewBindingCompleteEventArgs e)
    {

        for (int i = 0; i < this.myGrid.Rows.Count; i++)
        {
            if((this.myGrid.Rows[i].DataBoundItem as MyObject).Special)
            {
                this.myGrid.Rows[i].DefaultCellStyle.BackColor = Color.FromArgb(240, 128, 128);
            }
        }
    }

还有其他更好的选择吗？

您还可以将事件处理程序附加到RowPostPaint:

dataGridView1.RowPostPaint += OnRowPostPaint;

void OnRowPostPaint(object sender, DataGridViewRowPostPaintEventArgs e)
{
    MyObject value = (MyObject) dataGridView1.Rows[e.RowIndex].DataBoundItem;
    DataGridViewCellStyle style = dataGridView1.Rows[e.RowIndex].DefaultCellStyle;

    // Do whatever you want with style and value
    ....
}
