The Week is started at the start of the month but not ended at end of the month.
Is it possible to do it? 

 

Code :

        <telerik:RadGanttView x:Name="ganttView" TasksSource="{Binding Tasks}" VisibleRange="{Binding VisibleRange}">
            <telerik:RadGanttView.TimeRulerLines>
                <telerik:GroupTickLine>
                    <telerik:TickInterval Interval="OneMonth" />
                </telerik:GroupTickLine>
                <telerik:GroupTickLine>
                    <local:WeekTickInterval Interval="OneWeek" />
                </telerik:GroupTickLine>
                <telerik:MajorTickLine>
                    <telerik:TickInterval Interval="OneDay"  />
                </telerik:MajorTickLine>
            </telerik:RadGanttView.TimeRulerLines>
            <telerik:RadGanttView.Columns>
                <telerik:TreeColumnDefinition Header="Project" Width="AutoHeaderAndContent" MinWidth="200"/>
            </telerik:RadGanttView.Columns>
        </telerik:RadGanttView>

Hello Dhjiraj,

To achieve your requirement, you can create a custom tick interval and override its GetNext() method. I can see you are already creating a custom week interval (WeekTickInterval) where you can incorporate this logic. Basically, in the method override, you can check if the week enters the next month. In this case, you can remove the days in the next month from the return DateTime object.

protected override DateTime GetNext(DateTime dateTime)
{
	DateTime date = base.GetNext(dateTime);
	// here you can alter the date
	return date;
}
