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

Hi, Telerik!

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!

Regards,
Anatoliy

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.

Autocomplete's textbox clearing issue

Hi Guys,
I'm using RadAutocompleteBox from RadControls for WPF Q3 2012 in an MVVM Application.
Here is sample code:

<Controls:AutoCompleteBox

WatermarkContent="Select a location..."

DisplayMemberPath="Name"

TextSearchPath="Name"

SelectedItem="{Binding ImpactedLocation, Mode=TwoWay, ValidatesOnDataErrors=True}"

ItemsSource="{Binding AvailableImpactedLocations}"

IsEnabled="{Binding IsOpened}"

MaxDropDownHeight="400"

DropDownWidth="400"

/>

The SelectedItem is bound to an MVVM ViewModel.
My problem is when I want to clear the text displayed in the autocomplete's textbox by setting the ViewModel.ImpactedLocation = null;
the selectedItem is cleared, but the text displayed is still here.

How can I clear it please? Something's to do with the SearchText? (try to clear it too, but still not working)
Thank's for your help.
Kind regards,
JC

LinearScale: CustomItems spanning range

LinearScale.CustomItems spanning range

Is it possible to have a custom item inside a linear scale span a certain range of values?
When you use the attached property ScaleObject.Value, it centers the item at the specified value. However, I would like to have the left end of the item (e.g. an rectangle or border) at one value and the right end at another.

Thank you.
