How to add object inside grid cell

[Nicole]

I am attempting to insert a polygon inside a RadGrid cell in code behind; the actual polygon that is inserted will depend on some conditions not yet reflected in the code below.  I've built a sample polygon, but I can't find the method to add it to the cell.  Can anyone tell me what I need to do here?  This has to happen in the code behind; I can't do it in the XAML.

void gvAGSE_RowLoaded(object sender, RowLoadedEventArgs e)
{
    if (e.Row is GridViewRow && !(e.Row is GridViewNewRow))
    {
        foreach (GridViewCell cell in e.Row.Cells)
        {
            if (cell.Column.Header.ToString().Contains("%"))
            {
                double cellValue = (double)cell.Value;
                if (cellValue >= 0)
                {
                    cell.Background = GetFMCBackgroundColorCode(cellValue);
                    cell.Foreground = GetFMCForegroundColorCode(cellValue);
                    Polygon poly = downArrow(GetFMCForegroundColorCode(cellValue));
                    //cell.Child.Insert(poly);
                }
                else
                {
                    cell.Content = "N/A";
                }
            }
        }
    }
}

Hello,

 Generally the proper way to style conditionally the grid cells or load different elements in the grid cells is with style and template selectors.

Would that entail setting the Style in the column definition like so:

 

ColPercent.CellStyle = this.LayoutRoot.Resources["DownArrowStyle"] as Style

Or can I set it at the cell level, with something like (pseudocode):

cell.Style = new Telerik.Windows.Controls.ConditionalStyleSelector());

Or, do you have an example using C#?

Hello,

 You can find both declarative and C# examples in your local copy of our demos. 

All the best,
