            IsDragPreviewEnabled="False"
            IsDragTooltipEnabled="False"
  IsDropPreviewLineEnabled="False" >

Export GridView to XML and GroulColumnHeader problem

Hello.
I'm using this great example for exporting grid to xml: http://www.telerik.com/help/wpf/gridview-export.html.
Problem is that, I have ColumnGroups declared like:

<telerik:RadGridView.ColumnGroups>
                    <telerik:GridViewColumnGroup Name="Numer">
                        <telerik:GridViewColumnGroup.Header>
                            <TextBlock Text="Numer" HorizontalAlignment="Center" VerticalAlignment="Center" TextAlignment="Center" />
                        </telerik:GridViewColumnGroup.Header>
                    </telerik:GridViewColumnGroup>
(...)
</telerik:RadGridView.ColumnGroups>

And using it with column:

                    <telerik:GridViewDataColumn Name="col5" DataMemberBinding="{Binding Nazwa dokumentu}" Header="Wewnętrzny" Tag="nazwa" ColumnGroupName="Numer">
                        <telerik:GridViewDataColumn.AggregateFunctions>
                            <telerik:CountFunction Caption="Liczba dokumentów: "></telerik:CountFunction>
                        </telerik:GridViewDataColumn.AggregateFunctions>
                    </telerik:GridViewDataColumn>

Well, it does export to xml, but with this little problem: http://puu.sh/9g0pQ/c92b2e57f8.png

How can I export content (text) of textblock instead of System.Windows.Controls.TextBlock ?

RadTreeListView Column Width CellEditTemplate

Hi,

I have a RadTreeListView in my application.
I have severals columns using CellEditTemplate.

When the size of the element in the CellEditTemplate gets bigger than the column's, the column is not resized.

For example :
<telerik:GridViewDataColumn Header="{localization:Translate Key=PBODetailGrid_Perte, Default=PBODetailGrid_Perte}"
DataMemberBinding="{Binding Perte, Mode=TwoWay, Converter={StaticResource FormatAmountConverter},ConverterParameter='Perte'}"
TextAlignment="Right"
IsFilterable="False"
UniqueName="lblPerteRTL"
MinWidth="60" >
<telerik:GridViewDataColumn.CellEditTemplate>
<DataTemplate>
<TextBox Text="{Binding Perte,
Mode=TwoWay,
Converter={StaticResource FormatAmountNullConverter}}" HorizontalAlignment="Center"/>
</DataTemplate>
</telerik:GridViewDataColumn.CellEditTemplate>

When the size of the TextBox is more important than the size of the column, the column is not resized.
Some columns in my RadTreeListView don't use DataTemplate, and their width resize normally.

Do you have an idea on how I can manage this issue ?

Thanks by advance :)

Change default sorting for fields added at runtime

Hi,

Is it possible to programmatically change the default sorting for fields that are added through a RadPivotFieldList? Currently added fields have default sorting of Ascending (A to Z), but I would like to have no sorting.

Thanks,
Edwin

DataSeries Style

hi,

I use radchart in my project, since i use NoXaml dll, my DataSeries no longer displayed. I try to define the SerieStyle on the chart area and on the SplineAreaSeriesDefinition and PieSeries but it doesn't works.

In the OutPutWindow: i got a warning when i click on the legend : System.Windows.Data Warning: 4 : Cannot find source for binding with reference 'RelativeSource FindAncestor, AncestorType='Telerik.Windows.Controls.Charting.ChartLegend', AncestorLevel='1''. BindingExpression:Path=LegendItemMarkerShape; DataItem=null; target element is 'ChartLegendItem' (Name=''); target property is 'MarkerShape' (type 'MarkerShape')

This is the xaml code :

<telerik:RadChart telerik:StyleManager.Theme="Windows8" x:Name="radAreaChart" UseDefaultLayout="False" BorderThickness="0" Background="{x:Null}" BorderBrush="{x:Null}" >

<Grid>

<Grid.RowDefinitions>

<RowDefinition Height="auto"></RowDefinition>

<RowDefinition Height="*"></RowDefinition>

</Grid.RowDefinitions>

<Grid.ColumnDefinitions>

<ColumnDefinition Width="*"/>

<ColumnDefinition Width="auto"/>

</Grid.ColumnDefinitions>

<telerik:ChartTitle telerik:StyleManager.Theme="Windows8" x:Name="AreaChartTitle" HorizontalAlignment="Center" Content="{Binding Resource.ConnectionPerProfile}"

Grid.Row="0" Grid.Column="1" Background="{x:Null}" FontFamily="Segoe UI Semibold" BorderThickness="0" OuterBorderBrush="{x:Null}" FontSize="13.333">

</telerik:ChartTitle>

<telerik:ChartArea telerik:StyleManager.Theme="Windows8" Grid.Row="1" x:Name="AreaChart" Margin="0" LegendName="AreaChartLegend">

</telerik:ChartArea>

<telerik:ChartLegend telerik:StyleManager.Theme="Windows8" Grid.Row="1" x:Name="AreaChartLegend" Header="{Binding Resource.Legend}" Margin="-4,0" Grid.Column="1" />

</Grid>

</telerik:RadChart

And this is my C# Code to add Series

AreaChart.DataSeries.Clear();

AreaChart.AxisX.AutoRange = true;

AreaChart.AxisY.AxisStyles.AlternateStripLineStyle = this.Resources["HorizontalStripLineStyle"] as Style;

AreaChart.SeriesStyles.SplineAreaSeriesStyle = this.Resources["ScatterAreaSeriesStyle"] as Style;

DataSeries chartProfilesSeries = new DataSeries();

chartProfilesSeries.Definition = new SplineAreaSeriesDefinition();

chartProfilesSeries.Definition.SeriesStyle = this.Resources["ScatterAreaSeriesStyle"] as Style;

if (null != (this.DataContext as MainViewModel).LstChartTotalDateConnexion)

{

foreach (ChartsDateConnectionDTO c in (this.DataContext as MainViewModel).LstChartTotalDateConnexion)

{

chartProfilesSeries.Add(new DataPoint()

{

//Label = String.Format("{0} : {1} ", Strings.TotalOfconnection, c.Date.ToString("dd/MM")),

YValue = c.Connection,

XCategory = c.Date.ToString("dd/MM"),

Tooltip = String.Format("{0} du {1} ", Strings.TotalOfconnection, c.Date.ToString("dd/MM"))

});

}

chartProfilesSeries.Definition.SeriesName = String.Format("{0}", Strings.TotalOfconnection);

chartProfilesSeries.LegendLabel = String.Format("{0}", Strings.TotalOfconnection);

chartProfilesSeries.Definition.ShowItemToolTips = true;

chartProfilesSeries.Definition.ShowItemLabels = true;

chartProfilesSeries.Definition.InteractivitySettings.HoverScope = InteractivityScope.Series;

chartProfilesSeries.Definition.InteractivitySettings.SelectionScope = InteractivityScope.Series;

AreaChart.DataSeries.Add(chartProfilesSeries);

Thanks for you help

Best regards
