Hey guys,

I was wondering if there was anyway to force a floating-only pane to stay inside a certain boundary. For example, lets say I have a RadPane that takes up the top half of the screen. I would like the smaller floating pane to be restricted to stay inside that RadPane's border, so the user cannot 'float' the pane to the bottom half of the screen.

Is this possible?

Thanks,
Niko

DataFormDataField Label + Control widths

Is there any (easy) way to create a fixed width label with a variable width edit control (anchored at left, expands to fill available space to the right)? I am not AutoGenerating the fields, but I would prefer to use the telerik:DataFormDataField control for the sake of simplicity, rather than butcher together my own mess using a StackPanel or something similar.

I have a number of resizable forms, and the default way that labels and controls resize themselves doesn't really work that well.

Thanks,

Dan.

Validation message aren't displayed for RadNumericUpDown

Hello,

I'm currently working on a WPF application which has a few RadNumericUpDown controls and RadMaskedNumericInput controls.

We are working with data annotations to perform validation (including custom validation)

Now i've noticed that for RadMaskedNumericInput controls, it will display the validation message next to the control and change the border color to red.
However, for RadNumericUpDown controls it only changes the border to red but doesn't display the message.

Is this standard behaviour or am I missing something?

Kind regards,

NumericUpDown

Grid Fields Display Name Wrapping

Hi,

we would like to do some tweaks in Property Grid Fields styling. Sometimes the property names are too long and overlap with the fields.

I suppose the way to go is to edit the GridField template, but we are struggling to find it/generate it in Blend (using the Windows8 Theme).

Any ideas?
Thanks,
Stevo

Custom Style dynamic Inheritance of theme

I need to override default theme "Office_Black" and save ability for dynamically theme changing. I looked around this help (http://www.telerik.com/help/wpf/styling-apperance-themes-runtime.html). And found problem with inheritance styles. It's need using BasedOn attribute to inherite my default theme. This attribute is limited to StaticResources.
How can I dynamically change custom style base theme? Hope for the further request!

Creating Grid Lines in code

I have been working on a user control to simplify chart generation based on our needs. We adhere strictly to MVVM. I created a content control in XAML and am creating all of the Telerik charting in the view model and binding the chart to the content control. So far it has gone fairly smooth but with a hitch. I am trying to display the grid lines declared in code but the grid lines simply aren't showing up. Is it not possible to generate the grid with appropriate grid lines in code? Note that I have been focusing on the bar series in the following code:

public void Create2DCharting(ObservableCollection<CategoricalDataItem> data, NewChartTheme chartTheme)

{

this.ShowCartesian3DChart = false;

BarSeries barSeries = new BarSeries();

if (chartTheme.ColorBrushes.Count > 0)

{

for (int i = 0; i < data.Count; i++ )

{

data[i].Color = chartTheme.ColorBrushes[i];

}

if (chartTheme.ChartTp == ChartType.PieChart || chartTheme.ChartTp == ChartType.DoughnutChart)

{

this.ShowPieChart = true;

this.ShowCartesian2DChart = false;

this.PieChart = new RadPieChart();

this.PieChart.Palette = new ChartPalette();

foreach (CategoricalDataItem cdi in data)

PieChart.Palette.GlobalEntries.Add(new PaletteEntry(cdi.Color, cdi.Color));

if (chartTheme.ShowLegend)

{

this.ChartLegend = new RadLegend();

this.ChartLegend.Items = this.PieChart.LegendItems;

}

else

{

this.ShowPieChart = false;

this.ShowCartesian2DChart = true;

this.CartesianChart2D = new RadCartesianChart();

if (chartTheme.BackgroundColor != null)

this.CartesianChart2D.Background = new SolidColorBrush((Color)ColorConverter.ConvertFromString(chartTheme.BackgroundColor));

barSeries.HorizontalAxis = new CategoricalAxis();

barSeries.VerticalAxis = new LinearAxis();

if (chartTheme.ShowLegend)

{

this.ChartLegend = new RadLegend();

barSeries.ItemsSource = data;

barSeries.ValueBinding = new PropertyNameDataPointBinding("YValue");

barSeries.CategoryBinding = new PropertyNameDataPointBinding("XValue");

LegendItemCollection lic = new LegendItemCollection();

foreach (var d in data)

lic.Add(new LegendItem() { MarkerFill = (Brush)d.Color, MarkerStroke = (Brush)d.Color, Title = d.XValue });

this.ChartLegend.Items = lic;

}

else

{

barSeries.ItemsSource = data;

barSeries.ValueBinding = new PropertyNameDataPointBinding("YValue");

barSeries.CategoryBinding = new PropertyNameDataPointBinding("XValue");

}

switch(chartTheme.ChartTp)

{

case ChartType.BarChart :

if(chartTheme.ColorBrushes.Count > 0)

barSeries.PointTemplate = GetBarColorDataTemplate();

if (chartTheme.ShowGridLines)

this.CartesianChart2D.Grid = new CartesianChartGrid() { MajorLinesVisibility = GridLineVisibility.Y };

this.CartesianChart2D.Series.Add(barSeries);

break;

case ChartType.HorizontalBarChart :

barSeries.VerticalAxis = new CategoricalAxis();

barSeries.HorizontalAxis = new LinearAxis();

if(chartTheme.ColorBrushes.Count > 0)

barSeries.PointTemplate = GetBarColorDataTemplate();

this.CartesianChart2D.Series.Add(barSeries);

break;

case ChartType.LineGraph :

LineSeries lineSeries = new LineSeries();

lineSeries.HorizontalAxis = new CategoricalAxis();

lineSeries.VerticalAxis = new LinearAxis();

lineSeries.ItemsSource = data;

lineSeries.ValueBinding = new PropertyNameDataPointBinding("YValue");

lineSeries.CategoryBinding = new PropertyNameDataPointBinding("XValue");

lineSeries.PointTemplate = GetLineDataPointDataTemplate();

this.CartesianChart2D.Series.Add(lineSeries);

break;

case ChartType.PieChart :

PieSeries pieSeries = new PieSeries();

pieSeries.ItemsSource = data;

pieSeries.ValueBinding = new PropertyNameDataPointBinding("YValue");

PieChart.Series.Add(pieSeries);

break;

case ChartType.DoughnutChart :

DoughnutSeries doughnutSeries = new DoughnutSeries();

doughnutSeries.ItemsSource = data;

doughnutSeries.ValueBinding = new PropertyNameDataPointBinding("YValue");

PieChart.Series.Add(doughnutSeries);

break;

}

private DataTemplate GetBarColorDataTemplate()

{

StringReader markup = new StringReader(

@"<DataTemplate xmlns=""http://schemas.microsoft.com/winfx/2006/xaml/presentation"">" +

@"<Rectangle Fill=""{Binding DataItem.Color}""/>" +

@"</DataTemplate>");

XmlReader xmlReader = XmlReader.Create(markup);

return XamlReader.Load(xmlReader) as DataTemplate;

}

private DataTemplate GetLineDataPointDataTemplate()

{

StringReader markup = new StringReader(

@"<DataTemplate xmlns=""http://schemas.microsoft.com/winfx/2006/xaml/presentation"">" +

@"<Ellipse Height=""10"" Width=""10"" Fill=""{Binding DataItem.Color}""/>" +

@"</DataTemplate>");

XmlReader xmlReader = XmlReader.Create(markup);

return XamlReader.Load(xmlReader) as DataTemplate;

How to get the diagram position from a mouse click

Hi,

We display a context menu when the user right clicks a location within the RadDiagram. How would we get the position in the diagram where the user clicked?
This doesn't appear to be as simple as getting the MousePosition of the menu (or combining it with PointFromScreen) as we need to take account of Pan / Zoom / Scrolling.
