Sorting and Filtering with different ViewModels

Hi,

i have a problem with sorting and filtering. In my project i want to display a collection, in which are the items from different class type but have some same-named properties.
i.e.
ViewModelClassA : ViewModelBase
ViewModelClassB : ViewModelBase
ViewModelClassC : ViewModelBase
they all have the properties: Name, Description, Comment.
So i displayed this collection and want to use the sorting and filtering functions. Aber the filter and the sorting effect will not be shown.
I have tried to just take one type of my class, then everything is ok. I see the filter and the sorting effect.

Is there a discussion about this problem or even better there is already a solution for that? Thanks a lot!

Does your WPF grid support simple user-defined formulas like the Infragistics grid?

Hi, does your WPF grid support simple user-defined formulas like the Infragistics grid?

I'm looking at the possibility of port ing from Infragistics to you guys but I need functionality.

The feature is a formula button in the grid column header which has options to Sum, average, count, max, min the values. Once selected it inserts a special row under the header to show the results. If unselected it disappears. Attachment shows this.

Please let me know if you do or do not support this.

Thanks a lot.

QAT customization

Am I missing something, or is the user not able to add and remove buttons to the QAT at run-time?

On most RibbonView applications, it is possible for the user to add and remove various command to the QAT when running the application, thereby personalizing the menu. This does not seem to be possible out of the box with the Telerik RibbonView

Change EditTemplate for RadDataForm at runtime

I have a RadDataForm and an EditTemplate defined. What I would like to do is have two different EditTemplates based on user role (different fields and edit capabilities), and switch to the appropriate one at run time. Is there a way to do this?

NavigationBehavior

Hi,

for my application I created a UserControl which contain a RadScheduleView. We are looking forward to have a mechanism to customize a set of navigation keys, as an example, instead of using the arrow keys to navigate through the appointements and the slots, we want to let the user to determine which keys they want to up to navigate through the appointments and the slots. I would like to know if it's possible to have something like this through the NavigationBehavior or through something else?!?

Thank's
Alain

GridViewExpression and nested data

I have some hierarchical data where my Primary ItemSource is a List<foo> where foo contains a property List<MonthType> Months

In my gridView I can do the following and it displays the sub List<Months> amount information in columns

<telerik:GridViewDataColumn Header="Account Title" DataMemberBinding="{Binding AccountTitle}" />
<telerik:GridViewDataColumn Header="Jan" DataMemberBinding="{Binding Months[0].Amount}" />

...

But this does not work

<telerik:GridViewExpressionColumn Header="Total2" UniqueName="TotalValue2" DataFormatString="{}{0:C}" Expression="Months[0].Amount + ... + Months[11].Amount" />

If I put in a simple test - this works (Where RowID is a valid in in my data Object).

<telerik:GridViewExpressionColumn Header="Total" UniqueName="TotalValue" DataFormatString="{}{0:C}" Expression="RowID * 2" />

Any ideas on how to get this simple expressionColumn to work?

How to bind a ComboBox in a DataTemplate ~ non-MVVM way?

Hello, I would like to enquire on a solution to as per title.

If the ComboBox is simply a GridViewColumn, it would had been straight-forward like this:

((GridViewComboBoxColumn)gridPrintOption.Columns["PrintCode"]).ItemsSource = listPrintCode;

But now that it is in a DataTemplate (of a ListBox), it is more complicated as there's no direct means of accessing the controls.
Below are the codes of what I currently have, simplified:

<telerik:RadListBox Grid.Row="0" Grid.Column="2" Margin="0, 5, 5, 5"

x:Name="listBoxIssue" HorizontalAlignment="Left" VerticalAlignment="Top"

Height="690" Width="793"

ItemTemplate="{StaticResource lbIssueTemplate}" ItemsSource="{Binding}">

<DataTemplate x:Key="lbIssueTemplate">

<Grid Margin="0" Width="Auto">

<Grid.ColumnDefinitions>

<ColumnDefinition />

</Grid.ColumnDefinitions>

<Grid.RowDefinitions>

<RowDefinition />

</Grid.RowDefinitions>

<ComboBox x:Name="PrintCode" Grid.Row="0" Grid.Column="2" ItemsSource="{Binding}"

SelectedValuePath="PrintCode" DisplayMemberPath="PrintCode" />

</Grid>

</DataTemplate>

So basically I'm binding 2 different objects here. 1 to the ListBox, and 1 to the ComboBox. The object that binds to the ListBox has a property which is used as the "SelectedValuePath" of the ComboBox, while the object that binds to ComboBox simply provide the ComboBox with the list of options available for users to choose upon drop-down. Everything is fine as it is, but the only problem is I don't know how to bind the object to the ComboBox in non-MVVM way. If it were a GridViewColumn, I would have solved the problem as shown in my 1st code block.
