StartEdit

Hi,

In your documentation, it quotes "or programmatically by using the StartEdit() method of the RadTreeViewItem.". I have a treeviewitem, but VS complains; StartEdit is not a member of RadTreeviewItem.

Have I missed something, or was this method omitted from the build.

My requirement is to startedit a RadTreeviewItem in code

Thanks

Child table with column button

Hello,

First of all, sorry for my english ...

My application looks like your example "firstlook".

I have a master table, one child table on a tabitem and a chart on the other tabitem.

I succeed to create a column-button for the master table :

<telerik:RadGridView.Columns >

<telerik:GridViewColumn IsVisible="True" Width="30">

<telerik:GridViewColumn.CellStyle>

<Style TargetType="{x:Type telerik:GridViewCell}">

<Setter Property="Template">

<Setter.Value>

<ControlTemplate TargetType="{x:Type telerik:GridViewCell}">

<Grid>

<Button Width="18" Height="18" Click="AjoutFiche_Click" >



<Button.Content>

<Grid Width="8" Height="8" VerticalAlignment="Center" HorizontalAlignment="Center">

<Path Fill="{x:Null}" Stretch="Fill" Stroke="#FF000000" Margin="0.083,0.664,0,0" Data="M0.50001547,0.5 L6.5000797,6.5000169 M6.5000155,0.5 L0.5,6.5000704" StrokeThickness="2"/>

<Path Fill="#FFCE3527" Stretch="Fill" Stroke="#FFCD3527" Margin="0,0,0.083,0.664" Data="M0.50001547,0.5 L6.5000797,6.5000169 M6.5000155,0.5 L0.5,6.5000704" StrokeThickness="2"/>

</Grid>

</Button.Content>

</Button>

<Rectangle Width="{TemplateBinding VerticalLineThickness}"

Fill="{TemplateBinding VerticalLineFill}" HorizontalAlignment="Right"

Visibility="{TemplateBinding VerticalLineVisibility}" SnapsToDevicePixels="True" />

</Grid>

</ControlTemplate>

</Setter.Value>

</Setter>

</Style>

</telerik:GridViewColumn.CellStyle>

</telerik:GridViewColumn>

1)For the child table, I want the same thing :

a)Is it possible to create 2 columns-button (type button) ?

Each line of the child table has a column-button (type button) and a click on this button opens a window with the information of the line select

The purpose of the other column-button is to delete the line select.

b)Is it possible to create the columns in the XAML part and not in code behind ?

I hope that the description of my problem is clear

Thanks.

                    </telerik:RadGridView> 

            When user delete the content of the address column for the first row (The mandatory rules mark the cell as invalid) then scroll until the last row and rescroll on the first row, 

            the old content is displayed. Is there a way to leave the invalid content of a cell when user scroll down/up? (I know that wrap the 

            grid into a ScrollViewer avoid the virtualization but I prefer find another way, this bug occurs also on Grid with huge amount of data in my application)

Issue with multi-series Bar Chart

Hi,

I seem to have a problem with a multiple-series bar chart. I have a custom X-Axis, which works fine. The Y-Axis is simply a number of phone calls figure, so the auto-scale axis would be fine. However, the values do not seem to marry up with those in the bar series. The image below illustrates this (flickr link, not sure if you can embed pics on here) :

http://farm4.static.flickr.com/3325/3525153961_2d6272a1dc_o.jpg

As you can see, the rightmost green bar = 111, which seems to line up with the Y-axis - however, none of the others do.

The XAML for the chart is as follows (incomplete, the remainder is legend name, title etc):

                    <control:RadChart x:Name="skillBarChart"           
                            telerik:Theming.Theme="Office_Black"  >         
                                   <control:RadChart.DefaultView>         
                                     <chart:ChartDefaultView >         
                                        <chart:ChartDefaultView.ChartArea >         
                                            <chart:ChartArea    x:Name="BarChartArea"          
                                                                LegendName="CustomLegend"          
                                                                FontFamily="Arial" FontSize="18"          
                                                                Height="446.848" Width="985">         
                                                <chart:ChartArea.AxisX>         
                                                    <chart:AxisX    MajorGridLinesVisibility="Collapsed"         
                                                                    Title="Skill" />         
                                                </chart:ChartArea.AxisX>         
                                                <chart:ChartArea.AxisY>         
                                                    <chart:AxisY    MajorGridLinesVisibility="Collapsed"         
                                                                    MinorGridLinesVisibility="Hidden"          
                                                                    Title="Calls" AutoScale="True"          
                                                                    MinValue="0" MaxValue="500"/>         
                                                </chart:ChartArea.AxisY>         
                                                <chart:ChartArea.Background>         
                                                    <LinearGradientBrush    EndPoint="0.5,1" StartPoint="0.5,0">         
                                                            <GradientStop           Color="#FF000000" Offset="0"/>         
                                                            <GradientStop           Color="#FF63B2DE" Offset="1"/>         
                                                    </LinearGradientBrush>         
                                                </chart:ChartArea.Background>         
                                            </chart:ChartArea>         
                                        </chart:ChartDefaultView.ChartArea>         

I'm populating the chart as follows (again a snippet) :

                             
                                     
                                        foreach (string s in skillname)         
                                        {         
                                            DataPoint Idp = new DataPoint();         
                                            Idp.YValue = noOfInCalls[Array.IndexOf(skillname, s)];         
                                            Idp.XValue = Array.IndexOf(skillname, s);         
                                            series1.Add(Idp);         
                                                     
                     
                                            DataPoint Odp = new DataPoint();         
                                            Odp.YValue = noOfOutCalls[Array.IndexOf(skillname, s)];         
                                            Odp.XValue = Array.IndexOf(skillname, s);         
                                            series2.Add(Odp);         
                                        }         
                                skillBarChart.DefaultView.ChartArea.DataSeries.Add(series1);         
                                skillBarChart.DefaultView.ChartArea.DataSeries.Add(series2);         

I then reformat the X-Axis with specific values for the 'skillname' to which each Y value corresponds, but do not do anything with the Y-Axis. However, I still get the issue as shown in the image. The '120' marker in the image is also cut off by the chart title area which I cannot seem to resolve.

Any assistance gratefully received! Thanks!

Highlighting an item on a chart

I have a WPF application with a Line chart.

I have a bunch of things that I cannot figure out how to do...
(1) When I user selects a particular value (in another control), which can be used to identify a particular data point in my chart, I want to be able to "highlight" that point on my chart. Is it possible to do that?
(2) Is it possible to make the circle which represents each data item bigger?
(3) When I add more data to the dataseries, the distance between two points on the X Axis keeps shrinking. Is it possible to keep that distance constant and scroll horizontally instead?

Any help with this is greatly appreciated.

Thanks,
-Sunandini
