Hi,

My rad gridview becomes unresponsible for a couple of seconds while grouping certain amount of data. All I want to do is to show some kind of loading indicator for this period of time. I tried to leverage OnGrouping, OnGrouped events to set IsBusy but it does not work:



It looks like GridView performs all grouping in UI thread without any chance for 'IsBusy = true' being proceed before grouping finishes. 

Is this any recommended way to achieve this? I can't believe nobody meets this issue but forum search was unsuccessful :(  

Thanks in advance

Hi,

I try to display a chart with SeriesProvider using implicit style.

I work on the SDK sample project for series provider, I change the dll references to used the no-xaml ones and I add the implicit style on my themes folders.

When I try to provide some series, the text "no data to plot" is displayed, so the series are discovered but not the data...

I upload my project here : https://www.sendspace.com/file/qdkvzk


Thanks,

Hi,

When I place a RadGridView in the LargeContent part of a RadFluidContentControl the Column Headers are shown but no data is shown in the grid.

If I place the exact same RadGradView into the Content part of the same RadFluidContentControl all of the data is shown in the grid.

Any help would be appreciated.

Thanks
Anthony

I've transitioned all my geometry to MapShapeData objects, with the exception of MapPinPoint. I am still using those because they allow positioning over the center instead of the upper left corner. How can I create an EllipseData (for example) so that its center is at 30,-90 instead of its upper left corner at that coordinate?

I want draw scatter line chart like Excel X Y Scatter Chart.
I have data with null values that I want to plot on the scatter line chart,
When I tried to do that it shows points but there is no line connecting that points.

There are two series in my chart

Series 1
 At X axis- 2004/3/31  2004/12/31   2005/3/31 2005/12/31  2006/3/31 2006/12/31
 At Y axis-    2000               null               3000           null               4000          null

Series 2
 At X axis- 2004/3/31  2004/12/31   2005/3/31 2005/12/31  2006/3/31 2006/12/31
 At Y axis-    null               4000               null           5000               null          6000

when I tried to plot this data it showed only points at respective dates. So how to draw continuous line from start to end joining this points. 

Hello,

    I'm currently modifying the OrgChart example to add the ability to build a hierarchy inside a team (a team member can have children team member).
    To be able to know if the user is dragging a Team Member over another one I've modified the OgChartDiagram.GetShapeUnderPosition() to be able to get a list of shapes instead of the top shape :


My problem is that the method always return a single team item, never a team member.
(I also changed the inheritance of OrgTeamMemberViewModel to make it inherit from HierarchicalNodeViewModel instead of ViewModelBase..

is GetTopShapesUnderPoint() the right method to use for this ?

Thanks !

Hi, I want to get the main ribbon window's correct top/left location when it is maximized.
I set some pop-up dialogs' locations based on the main ribbon window's top/left location, and it works fine when it is in the restored state.
When I maximized it, however, the previous location before maximization seems to be used.
I could just use (0, 0) location for a single monitor maybe, but how can I get the right location for dual monitors?

Hi,
  I am using a RadMap that depicts a number of physical area around the map that are drawn with MapPolygons.  This works great.  I am trying to put text inside each corner of each MapPolygon to tell users what area they are viewing.  I need the scale of this text to match the map's scale as the user zooms in and out.  I have added labels with a number of approaches, but I always find that they don't scale correctly  when you zoom in.  For example, in the attached file you will see how the text gets very small as you zoom in.  In that file you will also see the way I need the text to look.

 In this example the following code gets executed for each corner in a given MapPolygon that I am trying to label:

                Grid grid = new Grid();
                grid.Background = new SolidColorBrush(Colors.White);
                TextBlock text = new TextBlock();
                text.Foreground = new SolidColorBrush(Colors.Purple);
                text.Text = "My Label Data";
                grid.Children.Add(text);

                Location newLocation = ... (based on MapPolygon corner)
                MapLayer.SetLocation(grid, newLocation);
                this.informationLayer.Items.Add(grid);

  Is there a way to add text to a RadMap and have it keep its location and scale correctly as a user zooms in/out?

Thanks.

I'm having problems adding CartesianGridLineAnnotations to my RadCartesianCharts. I've read the documentation on this page : http://www.telerik.com/help/wpf/radchartview-annotations-gridline.html and followed the example answer given in this forum post : http://www.telerik.com/forums/cartesian-chart-without-adding-new-axis-for-custom-line but whenever I try to add the annotation I get an error. 

In the forum post you give the following example: 

[code]
<telerik:RadCartesianChart x:Name="chart">
   <telerik:RadCartesianChart.VerticalAxis>
      <telerik:LinearAxis />
   </telerik:RadCartesianChart.VerticalAxis>
   <telerik:RadCartesianChart.Annotations>
   <telerik:CartesianGridLineAnnotation Axis="{Binding ElementName=chart, Path=VerticalAxis}" Value="25" />
[/code]

Which sets up the chart and axis, then adds the CartesianGridLineAnnotation, binding the Axis value to ther VerticalAxis in the element named "chart." 

My code is as follows:

[code]
<telerik:RadCartesianChart x:Name="SummaryChart" UseLayoutRounding="True" Grid.Row="1" TooltipTemplate="{Template}">
   <telerik:RadCartesianChart.HorizontalAxis>
      <telerik:CategoricalAxis LabelFitMode="Rotate" />
   </telerik:RadCartesianChart.HorizontalAxis>
                                              
   <telerik:RadCartesianChart.VerticalAxis>
      <telerik:LinearAxis />
   </telerik:RadCartesianChart.VerticalAxis>
                                              
   <telerik:RadCartesianChart.Annotations>
      <telerik:CartesianGridLineAnnotation Axis="{Binding ElementName=SummaryChart, Path=VerticalAxis}" Value="6" Stroke="Red" StrokeThickness="1"/>
   </telerik:RadCartesianChart.Annotations>
[/code]

As far as I can tell this is following your example of how to bind to the Vertical axis. 

However when I use this XAML I get the following binding error:

System.Windows.Data Error: 4 : Cannot find source for binding with reference 'ElementName=SummaryChart'. BindingExpression:Path=VerticalAxis; DataItem=null; target element is 'CartesianGridLineAnnotation' (Name=''); target property is 'Axis' (type 'CartesianAxis')

Do you know what I'm doing wrong? 

Thanks,

Andy.
