Get specific appointment element from scheduler

Hi!

In my code I'm creating new appointments in a scheduler by dropping them from a radGridView. Any ideas how can I get the last created appointment element of the scheduler, or the appointment element assigned to the newly created appointment?

private void svc_PreviewDragDrop(object sender, RadDropEventArgs e)
        {
            SchedulerCellElement schedulerCell = e.HitTarget as SchedulerCellElement;

            if (schedulerCell != null)
            {
                GridDataRowElement draggedRow = e.DragInstance as GridDataRowElement;
                if (draggedRow != null)
                {
                    if (draggedRow.Data.DataBoundItem != null)
                    {
                        if (draggedRow.GridControl.DataSource != null)
                        {
                            MainJobObject draggedMainJobObject = (MainJobObject)draggedRow.Data.DataBoundItem;
                            AppointmentWithObject appointment = new AppointmentWithObject(schedulerCell.Date, schedulerCell.Date.AddHours(1), draggedMainJobObject.Customer, " / ", draggedMainJobObject.MachineType);
                            appointment.Start = schedulerCell.Date;
                            appointment.End = schedulerCell.Date.AddHours(1);
                            appointment.AssignedMainJobObject = draggedMainJobObject;
                            appointment.ResourceId = schedulerCell.View.GetResourceId();
                            scheduler.Appointments.Add(appointment);

                            //CustomAppointmentElement appointmentElement = get the appointment element that was just created;
                            //if (appointmentElement != null)
                            //{
                            //    appointmentElement.ChangeStatus(2);
                            //}                         
                        }
                    }
                }            
            }          
        }

Disabling gridview column and collapsing button in CommandColumn

Hi,

I am having two issues with a RadGridView and need some help.

In the attached movie, there is a gridView with two "optional" columns : one with check boxes and one with buttons.

This is to allow a user to modify values in the associated DB Table either individually with the buttons or as a group via the check boxes.

However, I want only one column active at any time. The selection being done via the upper left label.

Note that I do not want the CommandColumn to be hiden, as the buttons labels also convey status information.

The problems are as follow :

1- when the form is loaded, I only want to show the lines where buttons in the "ready for update" state (written "Mettre à jour"). So I hide the other rows labelled "Not Ready". Doing this in the CellFormatting event works, but due to the virtualisation, as you can see in the attached movie, if the user move the colums too fast, the Not ready cells are temporarily displayed ( I tried a MasterTemplate.Refresh but this crash the form load with an index invalid exception in Telerik code).

How can I solved this ?

2 - when I click on the label (used as a button) to show the Check box column, it should change color in grey. As you can see, it does it (on the whole column as expected) but only if I click on any of the column button.

Here is the CellFormatting code :

  private void gvMajBoutique_CellFormatting(object sender, CellFormattingEventArgs e)
  {
      if (e.CellElement is not GridCommandCellElement commandCell) return;
      var row = commandCell.RowInfo;
      if (row == null) return;

      string ugs = row.Cells["Sku"].Value.ToString();
      if (ugs != null && SuiviDesModifications.ContainsKey(ugs))
      {
          StatusModifsPrixBoutique state = SuiviDesModifications[ugs];

          if (state == null) return;

          if (state.CurrentState == ChangeButtonState.UpdateReady)
          {
              commandCell.CommandButton.Text = state.CurrentButtonName;
              row.IsVisible = true;
          }

          else if (state.CurrentState == ChangeButtonState.UpdateForbidden)
          {
              row.IsVisible = false;
          }

          if (StatusColumnEnabled)
          {
              commandCell.CommandButton.ButtonFillElement.BackColor = Color.PapayaWhip;
              commandCell.CommandButton.ButtonFillElement.GradientStyle = Telerik.WinControls.GradientStyles.Solid;
              commandCell.CommandButton.Enabled = true;
          }
          else
          {
              commandCell.CommandButton.ButtonFillElement.BackColor = Color.LightGray;
              commandCell.CommandButton.ButtonFillElement.GradientStyle = Telerik.WinControls.GradientStyles.Solid;
              commandCell.CommandButton.Enabled = false;
          }
          // This crash the form //gvMajBoutique.MasterTemplate.Refresh();
      }
  }

Thanks for your answers

AppointmentFormatting depending on actual Resource possible?

Hello, I am using a scheduler, where my appointments can have multiple resources. A resource can be the a casual member or be responsible for the appointment. I want to achieve a custom formatting of the appointment element, depending on the following states:

- the current resource is the only member (automatically responsible)
- the current resource is member, but not responsible
- the current resource is responsible and appointment has other members.

The attached screenshot shows a single appointment with 2 members and a responsible. The drawn Icon shall be depending on the resource of the current row.

To achieve that task, I want to implement the AppointmentFormatting-Event and set the Icon of the AppointmentElement depending on the relative resouce state. But how do I determine the current resouce of the AppointmentElement?

Regards Stephan

Resource grouped RadScheduler drag & drop - get the assigned resource of the target cell

I have a timeline view scheduler grouped by Resources and would like to use the drag & drop service to move objects from my DataGridView to the scheduler. How do I determine the resource assigned to the cell that's my hit target (the cell I'm currently dropping into), so I can correctly set the ResourceID for the appointment I'm creating?

private void svc_PreviewDragDrop(object sender, RadDropEventArgs e)
        {
            SchedulerCellElement schedulerCell = e.HitTarget as SchedulerCellElement;
           
            if (schedulerCell != null)
            {
                GridDataRowElement draggedRow = e.DragInstance as GridDataRowElement;
                if (draggedRow != null)
                {
                    if (draggedRow.Data.DataBoundItem != null)
                    {
                        MainJobObject draggedMainJobObject = (MainJobObject)draggedRow.Data.DataBoundItem;
                        AppointmentWithObject appointment = new AppointmentWithObject(schedulerCell.Date, schedulerCell.Date.AddHours(1), draggedMainJobObject.Customer, " / ", draggedMainJobObject.MachineType);
                        appointment.Start = schedulerCell.Date;
                        appointment.End = schedulerCell.Date.AddHours(1);
                        //appointment.ResourceId = -- I need the resource ID HERE
                        scheduler.Appointments.Add(appointment);                     
                    }
                }            
            }          
        }

If it's not possible, I'd be happy with any trick or workaround that helps determining the resource that's assigned to the row the cell currently resides in - even determining the row number of the cell would help.

Color the task per resource

Hi,

I used example : https://docs.telerik.com/devtools/winforms/controls/ganttview/working-with-data/data-binding-basics

and added a column "Resource", it will help a lot if you can give me an example where every resource can have its OWN fill color to identify them quickly.

Thank you very much

Addig a GridViewTemplate to a RadGridView stops the DragAndDropService?

The Drag & Drop service is working perfectly on my RadGridView until I add a GridViewTemplate to it with the intent to create a hierarchy view, after which the drag events aren't even fired anymore. Any ideas, please?

This is how I initialize the Drag & Drop behavior on my main DataGrid:

private void InitGrid()
        {             
            bt_addAttachment.Visible = false;
            BaseGridBehavior gridBehavior = this.radGridView1.GridBehavior as BaseGridBehavior;
            gridBehavior.UnregisterBehavior(typeof(GridViewDataRowInfo));
            gridBehavior.RegisterBehavior(typeof(GridViewDataRowInfo), new CustomRowGridBehavior());

            //handle drag and drop events for the grid through the DragDrop service
            RadDragDropService svc = this.radGridView1.GridViewElement.GetService<RadDragDropService>();
            svc.PreviewDragStart += svc_PreviewDragStart;
            svc.PreviewDragDrop += svc_PreviewDragDrop;
            svc.PreviewDragOver += svc_PreviewDragOver;        
        }

        //required to initiate drag and drop when grid is in bound mode
        private void svc_PreviewDragStart(object sender, PreviewDragStartEventArgs e)
        {
            e.CanStart = true;
        }

        private void svc_PreviewDragOver(object sender, RadDragOverEventArgs e)
        {
            if (e.DragInstance is GridDataRowElement)
            {
                e.CanDrop = e.HitTarget is SchedulerCellElement;
            }
        }

        private void svc_PreviewDragDrop(object sender, RadDropEventArgs e)
        {
            SchedulerCellElement schedulerCell = e.HitTarget as SchedulerCellElement;
            if (schedulerCell == null)
            {
                //DayViewAllDayHeader allDay = (this.radScheduler1.SchedulerElement.ViewElement as SchedulerDayViewElement).AllDayHeaderElement;
                //schedulerCell = SchedulerUIHelper.GetCellAtPoint(e.DropLocation, allDay.Children);
            }
            if (schedulerCell == null)
            {
                return;
            }
            GridDataRowElement draggedRow = e.DragInstance as GridDataRowElement;
            if (draggedRow == null)
            {
                return;
            }

            DataRowView dataRowView = draggedRow.Data.DataBoundItem as DataRowView;
            if (dataRowView != null)
            {
                if (draggedRow.GridControl.DataSource != null && typeof(BindingSource).IsAssignableFrom(draggedRow.GridControl.DataSource.GetType()))
                {
                    Appointment appointment = new Appointment();
                    appointment.Start = (DateTime)draggedRow.RowInfo.Cells["Start"].Value;
                    appointment.End = (DateTime)draggedRow.RowInfo.Cells["End"].Value;
                    //adjust start/end according to target cell
                    appointment.End = schedulerCell.Date.AddMinutes(appointment.Duration.TotalMinutes);
                    appointment.Start = schedulerCell.Date;
                    appointment.Summary = string.Empty + draggedRow.RowInfo.Cells["Summary"].Value;
                    appointment.Description = string.Empty + draggedRow.RowInfo.Cells["Description"].Value;
                    appointment.Location = string.Empty + draggedRow.RowInfo.Cells["Location"].Value;
                    appointment.StatusId = (int)draggedRow.RowInfo.Cells["StatusId"].Value;
                    appointment.BackgroundId = (int)draggedRow.RowInfo.Cells["BackgroundId"].Value;
                    //this.radScheduler1.Appointments.Add(appointment);

                    dataRowView.Row.Table.Rows.Remove(dataRowView.Row);
                }
                else
                {
                    throw new ApplicationException("Unhandled Scenario");
                }
            }
        }

Which is working perfectly until I add this piece of code to it:

///attachments sub-row initialization
GridViewTemplate attachmentsTemplate = new GridViewTemplate();
attachmentsTemplate.AutoGenerateColumns = false;            
attachmentsTemplate.HierarchyDataProvider = new GridViewEventDataProvider(attachmentsTemplate);

GridViewTextBoxColumn columnMainJobID = new GridViewTextBoxColumn();
columnMainJobID.TextAlignment = ContentAlignment.MiddleCenter;
columnMainJobID.FieldName = "MainJobID";
columnMainJobID.IsVisible = false;
attachmentsTemplate.Columns.Add(columnMainJobID);

radGridView1.Templates.Add(attachmentsTemplate);
