Hi,

I'm seeing very degraded performance when I'm suign RowStyleSelector.
Here is my code for the selector. It is very simple. Is there anything I can do?

 

public class TimeReportGridRowStyleSelector : StyleSelector
{
    public Style LockedForEditingStyle { get; set; }
    public Style AlternateRowStyle { get; set; }
 
    public override Style SelectStyle(object item, DependencyObject container)
    {
        var row = item as ITimeReportRowItemBase;
 
        if (row != null && row.Locked)
            return LockedForEditingStyle;
 
        var items = ((GridViewRow)container).GridViewDataControl.Items;
 
        if (items.IndexOf(item) % 2 == 1)
            return AlternateRowStyle;
 
        return base.SelectStyle(item, container);
    }
}
