Hi Ondrej, 

 

Greetings from Syncfusion. 

 

1)To set hour format in timescale, we can achieve the requirement by setting the CellTextFormat in GanttScheduleRowInfo and binding the row collection in CustomScheduleSource as in the below code snippet. 

 

[C#] 

 

        public MainWindow() 

        { 

            InitializeComponent(); 

            Gantt.CustomScheduleSource = GetCustomScheduleSource(); 

        } 

 

        public IList<GanttScheduleRowInfo> GetCustomScheduleSource() 

        { 

            return new List<GanttScheduleRowInfo> 

               { 

                   new GanttScheduleRowInfo 

                       { 

                           TimeUnit = TimeUnit.Days, 

                           PixelsPerUnit = 45, 

                           CellTextFormat = "dd" 

                       }, 

                    new GanttScheduleRowInfo 

                       { 

                           TimeUnit = TimeUnit.Hours, 

                           PixelsPerUnit = 30, 

                           CellTextFormat = "hh" 

                       } 

               }; 

        } 

 

 

[XAML] 

  <sync:GanttControl x:Name="Gantt" 

                               ItemsSource="{Binding TaskCollection}" 

                               ResourceCollection="{Binding ResourceCollection}" 

                               VisualStyle="Metro" ScheduleType="CustomDateTime" > 

                <sync:GanttControl.TaskAttributeMapping> 

                    <sync:TaskAttributeMapping  TaskIdMapping="TaskId" 

                                                TaskNameMapping="TaskName" 

                                                StartDateMapping="StartDate"  

                                                ChildMapping="Child"                                             

                                                FinishDateMapping="FinishDate" 

                                                DurationMapping="Duration"  

                                                MileStoneMapping="IsMileStone" 

                                                ProgressMapping="Progress" 

                                                PredecessorMapping="Predecessor" 

                                                ResourceInfoMapping="Resources"/> 

                </sync:GanttControl.TaskAttributeMapping> 

            </sync:GanttControl> 

 

 

2) To change the hour format in Gantt columns, we can achieve it by setting style in StyleInfoClass as in the below code snippet. 

 

[C#] 

   private void Gantt_Loaded(object sender, RoutedEventArgs e)  

        {  

            for(int i=0;i< Gantt.GanttGrid.InternalGrid.Columns.Count;i++)  

            {  

                var column = Gantt.GanttGrid.InternalGrid.Columns[i];  

                if (column.HeaderText == "Duration")  

                {  

                    column.StyleInfo.TimeSpanEdit.Format = "hh:mm:ss";  

                }  

                else if(column.HeaderText == "Start" || column.HeaderText == "Finish")  

                {  

                    column.StyleInfo.DateTimeEdit.DateTimePattern = Syncfusion.Windows.Shared.DateTimePattern.CustomPattern;  

                    column.StyleInfo.DateTimeEdit.CustomPattern = "MM / dd / yyyy hh:mm:ss";                     

                }  

            }  

  

            Gantt.GanttGrid.Model.ColumnWidths[4] = 180;  

            Gantt.GanttGrid.Model.ColumnWidths[3] = 180;  

       Gantt.GanttGrid.InternalGrid.InvalidateCells(); 

        }  

    }  

 

 

 

Also, find the sample to implement it in the below link.
