Change the GanttGraphicalView Item and the Timeline.

[Zacharias Karasavvas]

Hi ,

I'm trying to change the GanttGraphicalView according to the timeline. For example if a task's duration is for 10 days I want to display the first 8 days for example with Green Color and the 2 that remains with red color. Is this possible and How can I do that in C# code ?

Is this possible ? Take a look a the Capture.PNG file.

Also I want to have a different display in my Gantt View.

The First Header I want to Have the current year(s) depends what I want every time and row below the year to have the Months . But not showing all the days of the month , just only the weeks.

Take a look at the second screenshot(Capture1.PNG).

The Header is the year ,  Below the year are the Months and each month is separated into four weeks.

Is it possible to have a format like that and how using c# ?

Appreciate any help you could give me.

Hello Zacharias,

Thank you for writing.

It is possible to create a RadGanttView as in the pictures you attached, however we do not have it out of the box. We have a kb article explaining in details how a custom GanttViewGraphicalViewElement, similar to the one in your second picture, can be accomplished. Basically would need to substitute the GanttViewGraphicalViewElement and for the purpose you would have to create and inherit several classes, here are the kb and the source code: Indicate Special Days in RadGanttView.

Regarding your other question, I think that you refer to the TaskProgressIndicatorElement. You can change the way it appears as well as the styling of the whole task item by subscribing to the GraphicalViewItemFormatting event. In the code snippet below I am showing you how this can be achieved:

private void radGanttView1_GraphicalViewItemFormatting(object sender, GanttViewGraphicalViewItemFormattingEventArgs e)
{
    GanttViewTaskItemElement taskItem = e.ItemElement as GanttViewTaskItemElement;
    if (taskItem != null)
    {
        taskItem.TaskElement.BackColor = Color.Red;
        taskItem.TaskElement.BackColor2 = Color.Red;
        taskItem.TaskElement.BackColor3 = Color.Red;
        taskItem.TaskElement.BackColor4 = Color.Red;

        GanttViewTaskElement taskElement = taskItem.TaskElement as GanttViewTaskElement;
        if (taskElement != null)
        {
            taskElement.ProgressIndicatorElement.MinSize = new Size(0, 19);
            taskElement.ProgressIndicatorElement.BackColor = Color.Green;
            taskElement.ProgressIndicatorElement.GradientStyle = Telerik.WinControls.GradientStyles.Solid;
        }
    }
}

I am also sending you a screenshot of the result on my side.

I hope this helps. Should you have further questions please do not hesitate to write back.
