在xtragrid和Scheduler之间拖放 [英] Drag and Drop between xtragrid and Scheduler

问题描述

有人可以告诉我如何从栅格控件和调度器控件之间拖放数据从devexpress？我想从网格拖动数据并将其放在调度器上。演示中的devexpress示例不适用于我。我只是得到一个块符号。

解决方案

得到它。

  private void grdGrid_MouseDown（object sender，MouseEventArgs e）
 {
 posImGrid = null; 
 
 GridHitInfo hitInfo = grvView.CalcHitInfo（new Point（e.X，e.Y））; 
 
 if（Control.ModifierKeys！= Keys.None）
 {
 return; 
} 
 
 if（（e.Button == System.Windows.Forms.MouseButtons.Left）&& 
（hitInfo.InRow）&& 
（hitInfo.HitTest！= GridHitTest.RowIndicator））
 {
 posImGrid = hitInfo; 
} 
} 
 
 private void grdGrid_MouseMove（object sender，MouseEventArgs e）
 {
 if（（e.Button == System.Windows.Forms .MouseButtons.Left）&& 
（posImGrid！= null））
 {
 Size dragSize = SystemInformation.DragSize; 
 Rectangle dragRect = new Rectangle（new Point（posImGrid.HitPoint.X  -  dragSize.Width / 2，
 posImGrid.HitPoint.Y  -  dragSize.Height / 2），dragSize）; 
 
 if（！dragRect.Contains（new Point（e.X，e.Y）））
 {
 grvView.GridControl.DoDragDrop（GetDragData（grvView），DragDropEffects.All）; 
 posImGrid = null; 
} 
} 
} 
 
 private SchedulerDragData GetDragData（GridView视图）
 {
预约终端= Storage.CreateAppointment（AppointmentType.Normal） ; 
 clsMeineKlasse tempObjekt =（clsMeineKlasse）grvView.GetFocusedRow（）; 
 termin.Description = tempObjekt.Beschreibung; 
 termin.Subject = tempObjekt.Bezeichnung; 
 termin.Duration = TimeSpan.FromHours（8）; 
 
 SchedulerDragData sdd = new SchedulerDragData（termin）; 
 
 return sdd; 
} 
  

someone can tell me how to drag and drop data between gridcontrol and schedulercontrol from devexpress? I want to drag the data from the grid and drop it on the scheduler. The devexpress example in the demo doesnt work for me. I just get a block-symbol.

解决方案

I got it.

 private void grdGrid_MouseDown(object sender, MouseEventArgs e)
        {
            posImGrid = null;

            GridHitInfo hitInfo = grvView.CalcHitInfo(new Point(e.X, e.Y));

            if (Control.ModifierKeys != Keys.None)
            {
                return;
            }

            if ((e.Button == System.Windows.Forms.MouseButtons.Left) &&
                (hitInfo.InRow) &&
                (hitInfo.HitTest != GridHitTest.RowIndicator))
            {
                posImGrid = hitInfo;
            }
        }

        private void grdGrid_MouseMove(object sender, MouseEventArgs e)
        {
            if ((e.Button == System.Windows.Forms.MouseButtons.Left) &&
                (posImGrid != null))
            {
                Size dragSize = SystemInformation.DragSize;
                Rectangle dragRect = new Rectangle(new Point(posImGrid.HitPoint.X - dragSize.Width / 2,
                                                             posImGrid.HitPoint.Y - dragSize.Height / 2), dragSize);

                if (!dragRect.Contains(new Point(e.X, e.Y)))
                {
                    grvView.GridControl.DoDragDrop(GetDragData(grvView), DragDropEffects.All);
                    posImGrid = null;
                }
            }
        }

        private SchedulerDragData GetDragData(GridView view)
    {
        Appointment termin = Storage.CreateAppointment(AppointmentType.Normal);
        clsMeineKlasse tempObjekt = (clsMeineKlasse)grvView.GetFocusedRow();
        termin.Description = tempObjekt.Beschreibung;
        termin.Subject = tempObjekt.Bezeichnung;
        termin.Duration = TimeSpan.FromHours(8);

        SchedulerDragData sdd = new SchedulerDragData(termin);

        return sdd;
    }
