    For a project level gantt chart i need to change the color of gantt task as per the project status. The possible project status can be more than two like Open, OnHold, Complete. Is there a way to change color based on condition.

    Hi Prolay,

    The easiest way of doing this is to bind the Background property of the EventContainer control to the property of the GanttTask holding this information using a ValueConverter. Here is an example how to do this if you have a property called Background of type Brush in your custom GanttTask:
    <telerik:RadGanttView VisibleRange="{Binding VisibleRange}" TasksSource="{Binding Tasks}">
            <Style TargetType="telerik:EventContainer">
                <Setter Property="Background" Value="{Binding OriginalEvent.Background}" />

    Here is the code of the custom GanttTask:
    public class CustomTask : GanttTask
        private Brush background;
        /// <Summary>Gets or sets Background and notifies for changes</Summary>
        public Brush Background
            get { return this.background; }
                if (this.background != value)
                    this.background = value;
                    this.OnPropertyChanged(() => this.Background);

    Hope this helps.
