I've tried setting the popup bound but it don't work

private void DropDownMenu_PopupOpened(object sender, EventArgs args)

{

var popup = sender as RadDropDownButtonPopup;

popup.SetBounds(10, 5, popup.Width, popup.Height);

}

Buttons, RadioButton, CheckBox, etc

Is there a better way to drag and drop grouped rows?

I have this code modified from example for moving rows between grids:

GridDataRowBehavior:

public class RowSelectionGridBehavior : GridDataRowBehavior

{

private List<GridViewRowInfo> selectedRows = new List<GridViewRowInfo>();

protected override bool OnMouseDownLeft(MouseEventArgs e)

{

GridDataRowElement row = this.GetRowAtPoint(e.Location) as GridDataRowElement;

if (row != null)

{

RadGridViewDragDropService svc = this.GridViewElement.GetService<RadGridViewDragDropService>();

svc.AllowAutoScrollColumnsWhileDragging = true;

svc.AllowAutoScrollRowsWhileDragging = true;

svc.Start(row);

}

return base.OnMouseDownLeft(e);

}

My extension of RadGridView

public delegate void MovingItemsEvent(List<GridViewRowInfo> rows, object source, object target);

public event MovingItemsEvent MovingItems;

//THIS IS THE PART I DON'T LIKE

private void ExtendedGrid_MouseDown(object sender, MouseEventArgs e)

{

if (e.Button == System.Windows.Forms.MouseButtons.Left && EnableDragnDrop)

{

GridGroupContentCellElement row = this.ElementTree.GetElementAtPoint(e.Location) as GridGroupContentCellElement;

if (row != null)

{

RadGridViewDragDropService svc = this.GridViewElement.GetService<RadGridViewDragDropService>();

svc.AllowAutoScrollColumnsWhileDragging = true;

svc.AllowAutoScrollRowsWhileDragging = true;

svc.Start(row);

}

private bool _EnableDragnDrop;

[BrowsableAttribute(true)]

public bool EnableDragnDrop

{

get { return this._EnableDragnDrop; }

set

{

_EnableDragnDrop = value;

if (value)

{

//register the custom row selection behavior

var gridBehavior = this.GridBehavior as BaseGridBehavior;

gridBehavior.UnregisterBehavior(typeof(GridViewDataRowInfo));

//gridBehavior.UnlockBehavior(typeof(GridGroupContentCellElement));

gridBehavior.RegisterBehavior(typeof(GridViewDataRowInfo), new RowSelectionGridBehavior());

}

private void svc_PreviewDragStart(object sender, PreviewDragStartEventArgs e)

{

if (EnableDragnDrop)

e.CanStart = true;

}

private void svc_PreviewDragOver(object sender, RadDragOverEventArgs e)

{

if (EnableDragnDrop)

e.CanDrop = true;

}

private void svc_PreviewDragDrop(object sender, RadDropEventArgs e)

{

if (EnableDragnDrop)

{

var dropTarget = e.HitTarget as RadItem;

var targetGrid = dropTarget.ElementTree.Control as RadGridView;

//append dragged rows to the end of the target grid

List<GridViewRowInfo> rows = new List<GridViewRowInfo>();

if (e.DragInstance is GridGroupContentCellElement)

{

e.Handled = true;

GridGroupContentCellElement group = e.DragInstance as GridGroupContentCellElement;

foreach (var row in group.ViewInfo.CurrentRow.ChildRows)

{

rows.Add(row);

}

this.MoveRows(targetGrid, rows);

}

else if (e.DragInstance is GridDataRowElement)

{

e.Handled = true;

foreach (var row in this.SelectedRows)

{

rows.Add(row);

}

this.MoveRows(targetGrid, rows);

}

private void MoveRows(RadGridView targetGrid, List<GridViewRowInfo> dragRows)

{

this.BeginUpdate();

targetGrid.BeginUpdate();

if (MovingItems != null)

{

MovingItems(dragRows, this, targetGrid);

}

this.EndUpdate(true);

targetGrid.EndUpdate(true);

}

This works fine without any problem, but I would like if ther is a better way to allow Grouped rows to be dragged, like for example registering a GridBehavior like in the case of ordinary rows

RadGridView with Hierarchy in Winforms

First, I'm new to Telerik Controls.

I'm trying to show a simple hierarchical class (some Properties and a List<T> with sub entries) in a RadGridView. I figured out I can use "AutoGenerateHierarchy" which works so far. But I'm having a real hard time to make it look how I need it. Especially for the sub entries. What ever I change in the Property Builder on "Template1" doesn't seem to have any effect. Also does it display a + even if the entry doesn't have sub entries.

I would appreciated if you could help me out with this...
