Hello,

I need to implement undo/redo on a RadScheduleView.

I need a way to capture the appointments as they are deleted by the end-user.

That way I can store them and add them back to the AppointmentsSource collection when the end-user performs an undo.

I am using MVVM and as such need to do this via data binding.

How can I do this?

Thanks in advance...

Hi,

I have used grouping and filtering programmatically in my  application by following the post below.
http://www.telerik.com/community/forums/wpf/gridview/group-aggregate-without-displaying-the-group-panel.aspx 

But after I upgraded my controls to 2012 Q1, the grouping event is not triggered at all.

Shouldn't this code prevent the close from happening?


The problem is that with the latest build 2012.2.620, after executing the following code, RadDocking throws an exception in Close() be cause the RadPaneGroup.Items have been cleared.  This does not happen in version 2012.2.607; in that version this works like a charm.

Thanks in advance,
Steve

Hi all
As i hover on item1 and the click outside the dropdownbutton, dropdownbutton does not closes. below is the code to reproduce it.
<telerik:RadRibbonDropDownButton Grid.Row="1">
            <telerik:RadRibbonDropDownButton.DropDownContent>
                <telerik:RadContextMenu>
            <telerik:RadMenuItem Header="Item1">
            <telerik:RadMenuItem Header="Item1.1" >
                
                </telerik:RadMenuItem>
            </telerik:RadMenuItem>
            </telerik:RadContextMenu>
            </telerik:RadRibbonDropDownButton.DropDownContent>
            </telerik:RadRibbonDropDownButton>

Thanks

 Here is the code where the theme for the GirdView is bound to the ViewModel's SelectedTheme property. The problem is with the custom header column that includes a checkbox. The UI has a combobox that allows the user to select a theme which is bound to the SelectedTheme property of the viewmodel. When I try to change the theme, I get the following exception:

Specified element is already the logical child of another element. Disconnect it first.

 If I comment out the section

<telerik:GridViewCheckBoxColumn.Header> from the code then it is fine. I don't get any exception when dynamically setting the theme for the gridview.

<telerik:RadGridView Name="radGridView"
                                         SelectionMode="Extended"
                                         EnableRowVirtualization="True"
                                         FrozenColumnCount="1"
                                         AlternationCount="2"
                                         AutoGenerateColumns="False"
                                         telerik:StyleManager.Theme="{Binding SelectedTheme}">
                        <telerik:RadGridView.Columns>
                            <telerik:GridViewCheckBoxColumn DataMemberBinding="{Binding IsSelected, Mode=TwoWay}"
                                                            EditTriggers="CellClick"
                                                            AutoSelectOnEdit="True">
 
                                <telerik:GridViewCheckBoxColumn.Header><!--this part throws exception if gridview is bound to the vm's theme property-->

                                                  VerticalAlignment="Center"
                                                  Click="chkAllSelect_Click"                                                  
                                                  IsChecked="{Binding AreAllSelected, Mode=TwoWay}" /> <!--this binding seems not possible-->
                                        <TextBlock Text="Select"
                                                   VerticalAlignment="Center"
                                                   Margin="5,0,3,0" />
                                    </StackPanel>
                                </telerik:GridViewCheckBoxColumn.Header> 
                            </telerik:GridViewCheckBoxColumn>                            
                        </telerik:RadGridView.Columns>
                    </telerik:RadGridView>

hello
i have a problem with the gridview
when i get the data from datatable to use in the grid the result is good but when i use the horizotal scroll to see a results(there are 30 column)the values disapear and the cells are empty!!
can you help me plz?
 there is a code:

In my usage of the ChartCiew I have three line series drawn on a chart per date, all of which share the same colour which are distinguished by using the DashArray property of the LineSeries class to make one solid, one dotted (1,1) and one dashed (3,3).  Each different date shown on the chart uses a different colour.

I can't seem to figure out how to make a legend that replicates the line drawn on the chart using the dash array property, do you have any advice? 

I have looked at your examples and can't see one that does what I want.

I can't really attach the code but I have attached an image showing a chart containing two LineSeries (one solid and one dashed) and my desired legend to indicate my requirements.

Thanks,

Hi,

is it possible to set the Root-Fodler of the FolderBrowserDialog from the  RadRichTextBoxribbonUI? <telerik:RadRichTextBoxRibbonUI>

in the Backstage Area i use this RadRibbonButton and the : telerik:RadRichTextBoxRibbonUI.RichTextCommand="{Binding Path=SaveCommand}"

Is it possible to set the RootFolder of the "SaveCommand"??? Something like RadRibbonButton.FolderDialog.SelectedPath= ??

Thanks a lot

The Data Service sample works fine when you instantiate a concrete service context object directly in the XAML of the RadDataServiceDataSource.

Should it be possible to data bind to the DataServiceContext property of a RadDataServiceDataSource instead?

I have an app that allows the choice of several OData services. When a service is chosen, I dynamically generate a service client proxy, and activate a new instance of that proxy's exported DataServiceContext-derived class. Now I want to bind that to my RadDataServiceDataSource (and of course change the binding to a completely different context if another OData service is chosen).
These are all read-only services, so I'm not concerned about maintaining any consistency of client-side update state.

It seems that when the DataServiceContext is set via a binding, the grid shows no data.

It seems that queries are never issued to the context:

System.ArgumentException: Could not find a matching query method on the DataServiceContext

Maybe the RadDataServiceDataSource is reflecting on the declared type of the bound property (DataServiceContext) instead of its runtime type (generated in the proxy and unavailable to me at design-time)?

Hi,

Is it possible to set the mail merge features via the UI to add text before and text after a field if it isn't empty?
I have seen that this is possible in code behind but I can't see to find a way to do it via the RadRichTextBox UI.

Thank you for your time,

Rob
