Hi,

I have the following code:

    
                        PieSeriesDefinition definition = new PieSeriesDefinition();  
        
                        definition.LegendDisplayMode = LegendDisplayMode.DataPointLabel;  
        
                        radChart1.DefaultSeriesDefinition = definition;  
        
                        DataSeries DS = new DataSeries();  
        
                        DataPoint DP = new DataPoint();  
        
                        DS.LegendLabel = "Over25";  
        
                        DP.YValue = 66;  
        
                        DS.Add(DP);  
        
                        radChart1.DefaultView.ChartArea.DataSeries.Add(DS);  
        
                        DataSeries DS2 = new DataSeries();  
        
                        DataPoint DP2 = new DataPoint();  
        
                        DS2.LegendLabel = "Over20";  
        
                        DP2.YValue = 100;  
        
                        DS2.Add(DP2);  
        
                        radChart1.DefaultView.ChartArea.DataSeries.Add(DS2);  
        
                        DataSeries DS3 = new DataSeries();  
        
                        DataPoint DP3 = new DataPoint();  
        
                        DS3.LegendLabel = "Over15";  
        
                        DP3.YValue = 120;  
        
                        DS3.Add(DP3);  
        
                        radChart1.DefaultView.ChartArea.DataSeries.Add(DS3);  
        
                        DataSeries DS4 = new DataSeries();  
        
                        DataPoint DP4 = new DataPoint();  
        
                        DS4.LegendLabel = "Over10";  
        
                        DP4.YValue = 113;  
        
                        DS4.Add(DP4);  
        
                        radChart1.DefaultView.ChartArea.DataSeries.Add(DS4);  
        
                        DataSeries DS5 = new DataSeries();  
        
                        DataPoint DP5 = new DataPoint();  
        
                        DS5.LegendLabel = "Under10";  
        
                        DP5.YValue = 178;  
        
                        DS5.Add(DP5);  
        
                        radChart1.DefaultView.ChartArea.DataSeries.Add(DS5);

But this is producing a bar chart. how do I make it a Pie chart?

Cheers,
Kevin.

WPF and Silverlight

I am about to start a new app that will be both WPF and Silverlight. I noticed for both WPF and Silverlight RadControls that you state

"Common Codebase and Shared API with WPF Controls"

That's great but the components that I really like in Silverlight, Drag & Drop, Docking and Toolbar/Menu/ContextMenu are not in WPF. Are there plans to add these to WPF

Regards,

Dan R.

[Solved] AutoGenerateColumns Moved

Hi,

In your documentation for Q1 2009 SP2 (version 2009.1.526) WPF RadGridView it states that:-
"AutoGenerateColumns moved from RadGridView to GridViewDataControl"
however AutoGenerateColumns appears as an option when editing the radGridView node in xaml

Removing Nodes - LoadOnDemand

Hi,

Can you give me and example of removing nodes from your RadTreeView as the code snippet below generates an error, at line

    
            Parent.Items.Remove(DirectCast(e.Source, TreeViewItem))

    
             Private Sub trvListEvents_Edited(ByVal sender As Object, ByVal e As Telerik.Windows.Controls.RadTreeViewItemEditedEventArgs) Handles trvListEvents.Edited  
        
                    If e.OldText <> e.NewText Then 
        
                        ActionMenuRequest(DirectCast(e.Source, RadTreeViewItem))  
        
                    Else 
        
                        Dim Parent As RadTreeViewItem = Me.CurrentTreeViewItem.Parent  
        
                        Parent.Items.Remove(DirectCast(e.Source, TreeViewItem))  
        
                    End If 
        
                End Sub

Requirements: After Editing a node, if it does not meet a certain criteria, then delete the node.

Note: I am using the RadTreeView with LoadOnDemand

Best

[Solved] Design time performance is verry poor

Every time I open a new file or trying to view a component properties, well, lets make it short, it happens no metter what i do, the window just gets stuck for 10-30 seconds and the cpu goas up to 100% until the command is performed.

Is there any way to make the conrol work faster at design time?

Thank you.

Unwanted horizontal scrollbar in Caramel theme

I'm using the Caramel theme and somehow, the last column is a little bit over on the right side and thus, making the horizontal scrollbar appears. If I changes the theme to Office_Black, everything is fine. Below is the code used and some screenshot to make it more clear:

                    <telerik:RadGridView Name="radGridView1" telerik:StyleManager.Theme="Caramel"         
                                                 ShowGroupPanel="False" IsFilteringAllowed="True"         
                                                 Foreground="Black" Margin="10,30,10,20" AutoGenerateColumns="False"         
                                                 RowIndicatorVisibility="Collapsed" ColumnsWidthMode="Fill">         
                     
                                <telerik:RadGridView.Columns>         
                                    <telerik:GridViewDataColumn UniqueName="Title" HeaderText="Title" IsFilterable="False" />         
                                    <telerik:GridViewDataColumn UniqueName="Artist" HeaderText="Artist" Width="Auto" />         
                                    <telerik:GridViewDataColumn UniqueName="Key" HeaderText="Key" Width="Auto"/>         
                                </telerik:RadGridView.Columns>         
                            </telerik:RadGridView>         

Caramel theme screenshot: http://www.notesnhac.com/TestFTP/ThemeCaramel.gif

You can see the filter icon got covered up for a small part on the last column (Key).

Office_Black them screenshot: http://www.notesnhac.com/TestFTP/ThemeOfficeBlack.gif

No horizontal scrollbar, and the icon shows up perfectly.

How do I fix this issue with the Caramel theme?

Thank you very much,

Kenny.

GridView Filtering

Hello,

I implemented a control containing a Rad GridView and a text box for instant filtering (similar to your sample examples). I noticed that the custom filtering overrides the filtering set by the drop-down filter (contained on the column headers) menus. From what I understood, the custom filter solution that you provide in the examples alters the GridViewDataControl.FilterDescription property which is used by the drop-down filters on the column headers. Is it possible to have both filters working together? Or is it at least possible to switch back and forth between these two filtering methods?

Thank you.

New Treeviewitem - Fails on BeginEdit

Hi

given the code below is there any reason why my NewNode.Begin edit is causing an exception - object ref not set to an instance of an object. This works fine if I omit the BeginEdit

    
              Dim NewNode As New RadTreeViewItem  
        
                    NewNode.Header = Now  
        
                    Me.CurrentTreeViewItem.IsExpanded = True 
        
                    Me.CurrentTreeViewItem.Items.Add(NewNode)  
        
                    NewNode.IsSelected = True 
        
                    NewNode.BringIntoView()  
        
                    NewNode.BeginEdit()

Thanks

[Solved] Recover Space

Is there a way to recover the area that was being used by the expander when the expander is collapsed? I have the event captured and I have the contents set to Collapsed but the space is still left on the screen rather than yielding it to the other row in the grid.
