Sort grid by color

[Vladimir]

Hello,
          I have a GridView with some rows colored and some not. I would like to display the color rows on top and the none color rows on the bottom. Is there a way I can Sort by color?

Hello Vladimir,

Thank you for contacting Telerik Support.

It is possible to sort the RadGridView by Color property. It is necessary to use Color.Empty value for none color cells. Thus when sorting (ascending), the empty value is on the bottom:

public Form1()
{
    InitializeComponent();

    List<Color> colors = new List<Color>()
    {
        Color.Red, Color.Empty, Color.Yellow, Color.Green,
        Color.Black, Color.Empty, Color.Fuchsia, Color.Pink,
        Color.Gray, Color.Blue
    };
    List<ColorItem> list = new List<ColorItem>();
    for (int i = 0; i < 10; i++)
    {
        list.Add(new ColorItem(i,colors[i],colors[i].ToString()));
    }
    radGridView1.DataSource = list;
    radGridView1.EnableSorting = true;
}

public class ColorItem
{
    public int ID { get; set; }

    public Color Color { get; set; }

    public string Description { get; set; }

    public ColorItem(int iD, Color color, string description)
    {
        this.ID = iD;
        this.Color = color;
        this.Description = description;
    }
}

If it is necessary to use some custom logic when sorting, you may use Custom Sorting. More information about it can be found in the referred help article.

I hope this information helps. Should you have further questions, I would be glad to help.
