Sorry if this is a bad question but I want to configure the grid lines in the RadGridView. This Post https://www.telerik.com/forums/change-color-of-the-grid---radgridview says I have to use Visual Style Builder and edit the theme.... Do I really have to dig into this massive thing?! Thats a total overload...? All I want is to configure the grid lines?

create padding inside the cartesian area?

I'm trying to figure out how to create some padding inside the coordinate space of the chart. Things I have done:
Set categorical axis axisplotmode to OnTicksPadded
Increased Padding on Chart.View.Margins (this seems to be the padding between the chart itself and stuff outside the chart)

See the picture below for an example. Basically datapoints aren't fully displaying because the points are being cutoff because the last Y-axis Tick is literally at the same Y location as the top of the chart. I'd like to move it down a bit to give the datapoints some space. Essentially create extra space around the edges of the axes. I have one axes that's a categorical axis and one that's a linear axis.

BarSeries and IsVisible

Create BarSeries:

_barModel = new BarSeries
{
ValueMember = "Model",
CategoryMember = "N",
LegendTitle = "Model",

IsVisible = false
};
_radChartViewGss.Series.Add(_barModel);

Set data source (dataTable):

_radChartViewGss.DataSource = _table;

After this, changing the property _barModel.IsVisible = true does not lead to anything - the bar series is not visible.

Why???

[Solved] Legend items horizontal instead of vertical

Hi.

Probably an easy question, but trying for a while, searching in the doc and the forum, I could not find the solution.

When I use a legend in radchartview, it shows the items below each other (vertically). But I would like to show them next to each other (horizontally).

Among others, I tried:

this.radChartView2.ChartElement.LegendElement.TextOrientation = Orientation.Horizontal;

or

this.radChartView2.ChartElement.LegendElement.StackElement.TextOrientation = Orientation.Horizontal;

But it does not seem to work...

Thank you

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
