MVVM ColumnDefinitions

[robert]

Hello, is there a possibility to bind a list of columndefinition in viewmodel on GanttGrid without direct access to the gantcontrol (gantt.Columns.add)?
Best Regards Robert ...
​

public void InitGanttColumns()
        {
            //Title ----
            ColumnDefinition GanttColumn = new TreeColumnDefinition();
            GanttColumn.Header = "Title";
            GanttColumn.Width = 200;
            GanttColumn.MemberBinding = new Binding("Title");
            GanttColumns.Add(GanttColumn);

            // Start ----
            GanttColumn = new ColumnDefinition();
            GanttColumn.Header = "Start";
            GanttColumn.Width = 100;

            var itemsBinding = new Binding("Start")
            {
                Converter = new GanttModuleTypeConverter(),
                ConverterParameter = "date"
            };

            GanttColumn.MemberBinding = itemsBinding;
            GanttColumns.Add(GanttColumn);

            // End ----
            GanttColumn = new ColumnDefinition();
            GanttColumn.Header = "End";
            GanttColumn.Width = 100;

            itemsBinding = new Binding("End")
            {
                Converter = new GanttModuleTypeConverter(),
                ConverterParameter = "date"
            };

            GanttColumn.MemberBinding = itemsBinding;
            GanttColumns.Add(GanttColumn);
        }

Hello Robert,

I am afraid that Columns property of the GanttView is not bindable, You could try to implement the needed approach with attached property as demonstrates in the following blog post;
http://blogs.telerik.com/xamlteam/posts/13-01-14/extending-the-functionality-of-radcontrols-with-attached-properties

However, please note that we haven't tested this and we cannot guarantee that it will work without any problems.
