Hello Niko,

Thank you for your post. I have been investigating into the issues that you have listed, and I have some information for you on them. I will address these issues in the order that they are listed.

1. You are likely not receiving any change notifications, as the XamGantt.ActiveRow property binds OneWay by default. I would recommend that you set the Mode of your binding to “TwoWay” in order to receive change notifications when your ActiveRow changes.

2. In order to change the color of each Gantt bar individually, I would recommend including the default style for “GanttNormalTaskPresenter” and all of its dependencies. This default style and its dependencies exist in the generic.shared.xaml file commonly found at the following directory:

C:\Program Files (x86)\Infragistics\<your version here>\WPF\DefaultStyles\Gantt

Once you include this style and its dependencies, I would recommend that you locate a Grid with its Visibility bound to “{TemplateBinding ComputedMiddleBarVisibility}.” Inside, you will find five Rectangle objects. These Rectangles are the Gantt bars, and if you bind their Fill properties, you can essentially bind the colors of the Gantt bars, individually. I would recommend a binding like the following:

Fill=”{Binding RelativeSource={RelativeSource TemplatedParent}, Path=Task.DataItem.TaskBrush}”

Breaking this binding down, the TemplatedParent would bind up to the GanttNormalTaskPresenter, which has a reference to the underlying ProjectTask that will be created for it. This ProjectTask has a DataItem property which will return the item that you are using for the ListBackedProject mapping, and in this case, that item would have a TaskBrush property of your creation to determine the brush color.

3. Filtering in the XamGantt is intentionally suppressed, as it is only implemented on the columns that are publically accessible, and is not implemented at all on the chart-side of things as the visibility of the rows in the grid versus the chart work completely independent of one another.

There is a slightly hacky way that you can enable filtering, though, and that would be to get the ProjectTableGrid from the XamGantt programmatically and enable filtering on it. An operation like this could look like the following:

//In perhaps, the Loaded event of the XamGantt…
XamGantt gantt = sender as XamGantt;
ProjectTableGrid grid = Utilities.GetDescendantFromType(gantt, typeof(ProjectTableGrid), false) as ProjectTableGrid;
grid.FilteringSettings.AllowFiltering = Infragistics.Controls.Grids.FilterUIType.FilterMenu;

Again though, keep in mind that the filtering will have no effect on the chart-side of the XamGantt, and will only work for certain columns, and so I would personally recommend against this operation.
