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

add column groups and ungroup to datagridview

Hi all,In my winForm program, I made some GridView columns programmatically. and after adding them to GridView
I tried to make just some headers in a group view style. the problem is when I apply this view changes, the gridview don't load
other columns which haven't been grouped.
the code I used to change the view is in below and notice I wrote them after adding columns to DGV. Thanks in advance
...
//adding 8 columns to DGV programmatically
....
//make just 6 column in a group format
ColumnGroupsViewDefinition view = new ColumnGroupsViewDefinition();
dataGridView1.ViewDefinition = view;
view.ColumnGroups.Add(new GridViewColumnGroup("morning));
view.ColumnGroups[1].Rows.Add(new GridViewColumnGroupRow());
view.ColumnGroups[1].Rows[0].Columns.Add(this.dataGridView1.Columns["MrnngEnt"]);
view.ColumnGroups[1].Rows[0].Columns.Add(this.dataGridView1.Columns["MrnngExit"]);
view.ColumnGroups.Add(new GridViewColumnGroup("evnng"));
view.ColumnGroups[2].Rows.Add(new GridViewColumnGroupRow());
view.ColumnGroups[2].Rows[0].Columns.Add(this.dataGridView1.Columns["EvnngEnt"]);
view.ColumnGroups[2].Rows[0].Columns.Add(this.dataGridView1.Columns["EvnngExit"]);
view.ColumnGroups.Add(new GridViewColumnGroup("over"));
view.ColumnGroups[3].Rows.Add(new GridViewColumnGroupRow());
view.ColumnGroups[3].Rows[0].Columns.Add(this.dataGridView1.Columns["OvrEnt"]);
view.ColumnGroups[3].Rows[0].Columns.Add(this.dataGridView1.Columns["OvrExit"]);
}

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...

Header of graphical view in 5 minute increments

Hello, I have tried modifying https://docs.telerik.com/devtools/winforms/ganttview/timeline/custom-timeline to have it do custom ranges, however when I run my copy I get a fully blank header. See attached for images.

My setting the custom behavior:

radGanttView1.GanttViewElement.GraphicalViewElement.TimelineStart = start; // Start is a DateTime

radGanttView1.GanttViewElement.GraphicalViewElement.TimelineEnd = end; // End is a DateTime

radGanttView1.GanttViewElement.GraphicalViewElement.OnePixelTime = TimeSpan.FromMinutes(0.0025);

radGanttView1.GanttViewElement.GraphicalViewElement.TimelineRange = TimeRange.Custom;

var behavior = new WarehouseTimelineBehavior { Start = start, End = end };

radGanttView1.GanttViewElement.GraphicalViewElement.TimelineBehavior = behavior;

And my Behavior class:

MaskedEditBox button

Hello Telerik Team !

I currently try to achieve something similar to the attached picture.

Maybe I took the wrong direction, by using a MaskedEditBox with a DateTime MaskType, I am trying to add an adjacent button picture to open a calendar, and also a drop down button with several standard choice.

By editing UI Elements I notice the presence of a StackLayoutPanel with LightVisualButtonElement, I put both Visibility to Visible and add a little calendar icon image.

I can see It on Visual Studio, but the icon does not appear when I launch the program, and also I don't have any idea what kind of event I need to add if I succeed in showing the icon to open a calendar control to select my date.

So maybe I took a wrong direction by using this controls ?

Any help or suggestion would be highly welcome

Thanks in adavnce
