背景与 index 属性绑定来应用背景,但我需要为此的逻辑。我想要如下所示的gridview。

int i=0;
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (i == 0)
{
e.Row.Cells[0].BackColor = System.Drawing.Color.Purple;
e.Row.Cells[1].BackColor = System.Drawing.Color.Green;
e.Row.Cells[2].BackColor = System.Drawing.Color.Red;
i++;
}
else if (i == 1)
{
e.Row.Cells[0].BackColor = System.Drawing.Color.Green;
e.Row.Cells[1].BackColor = System.Drawing.Color.Red;
e.Row.Cells[2].BackColor = System.Drawing.Color.Purple;
i++;
}
else if (i == 2)
{
e.Row.Cells[0].BackColor = System.Drawing.Color.Red;
e.Row.Cells[1].BackColor = System.Drawing.Color.Purple;
e.Row.Cells[2].BackColor = System.Drawing.Color.Green;
i = 0;
}
}

终于找到了解决方案,我自己:)
public class IndexToColorConverter : IValueConverter
{
public object Convert(object value, Type targetType, object parameter, string language)
{
SolidColorBrush _color = null;
int _val = (int)value % 9;
switch (_val)
{
case 1:
case 3:
case 8:
_color = App.Current.Resources["GreenBrush"] as SolidColorBrush;
break;
case 0:
case 5:
case 7:
_color = App.Current.Resources["OrangeBrush"] as SolidColorBrush;
break;
case 2:
case 4:
case 6:
_color = App.Current.Resources["PurpleBrush"] as SolidColorBrush;
break;
}
return _color;
}
public object ConvertBack(object value, Type targetType, object parameter, string language)
{
throw new NotImplementedException();
}
}
