Hi

If I can bind directly please advise how.

Many thanks.

Data Series from columns

I have the following linq code...

    
            var CVDOverviewData = from cvdo in pieData.CVDOverviews  
        
                                              select new  
        
                                              {  
        
                                                OverTwentyfive = cvdo.OverTwentyfive,  
        
                                                OverTwenty = cvdo.OverTwenty,  
        
                                                OverFifteen = cvdo.OverFifteen,  
        
                                                OverTen = cvdo.OverTen,  
        
                                                LessTen = cvdo.LessTen  
        
                                              };

the result is a sinlge row with a column for each range (over25, over20, over15 ...)

How so I get these values into a pie chart?

Sorry if this is a real newbie question.

Cheers in advance.

Q1 2009 SP2 Demo No Luck

Hi

I am unable to run your demo's online, with IE or with Firefox. So I modified the demo's app config (installed on my machine) to point to Northwind on SQL server 2005, so I can peruse the grid demo's. Putting a trace on SQL server it traces the following TSQL

SELECT [t0].[EmployeeID], [t0].[LastName], [t0].[FirstName], [t0].[Title], [t0].[TitleOfCourtesy], [t0].[BirthDate], [t0].[HireDate], [t0].[Address], [t0].[City], [t0].[Region], [t0].[PostalCode], [t0].[Country], [t0].[HomePhone], [t0].[Extension], [t0].[Photo], [t0].[Notes], [t0].[ReportsTo]
FROM [dbo].[Employees] AS [t0]

Then the Demo dies, with no stack trace

What can I do (where can I go) to see the features of your grid

WPF Combobox

Any news or thoughts on a Telerik combobox. The one that ships with VS2008 is fairly limited and does not work as users would like. For example, using the up and down keys and then selecting item with tab key.

Creating a Pie chart

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);

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.

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

Design time performance is verry poor

Hi,

I'm having a pre purchase test for RadGridView.

I try to develop a small test program with one grid on an xbap application.
Whenever I place a RadGridView control on my page (at design time), my visual studio 2008 start to work verry slow.
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>
