Do telerik WPF controls support XBAP in medium trust mode? I found no info about it on telerik.com, neither XBAP online demos, only ClickOnce demos. However I've found some links in old forum threads leading to the XBAP demos (http://demos.telerik.com/wpf#Telerik.Windows.Examples.xbap for example), none of them working now.

Customizing autocomplete datasource?

I have a combobox displaying 3 separate fields from the data source (using data template)

I would like to have autocomplete search any of these fields as the user types.

Is there a way to customize the way autocomplete works or modify the source of data which it is searching through to get this to work?

For example I am displaying first name, last name, and id in the combo box

and I would like the user to be able to start typing the first name or the last name or the id and have autocomplete select hits from any of those fields as the user types.

Specify an exact number of visible time slots

I have a schedule view control that I have in timeline view, however, the slots are far too small to be of use. I have noticed that the scheduler control had a property you could set on the timeline view called 'numberofslots' This seemed to set the exact number of visible slots and they would grow to fill the space. Is there a property that would accomplish the same thing for the schedule view control?

I have a grid that I have set the IsReadOnly to true. When I am in the grid on any cell, if I press the Enter key, I get the following error.

Unable to cast object of type 'System.Windows.Input.KeyEventArgs' to type 'FullyLoadedCostLibrary.BareDriveCosts'.

I'm using version 2011.2.712.40 WPF

My grid is defined

        <telerik1:RadGridView Name="bareDriveCostsListRadGridView"
               DataContext="{StaticResource bareDriveCostsListViewModelModelViewSource}" 
			   ItemsSource="{Binding ValidatesOnDataErrors=True, NotifyOnValidationError=True, ValidatesOnExceptions=True, NotifyOnTargetUpdated=True, NotifyOnSourceUpdated=True}" AutoGenerateColumns="False" CanUserDeleteRows="False"
               AutoExpandGroups="True" DataLoaded="bareDriveCostsListRadGridView_DataLoaded" SelectionUnit="Cell"
               IsReadOnly="{Binding Source={StaticResource bareDriveCostsListViewModelViewSource}, Path=CanEdit, Converter={StaticResource NotConverter}}">

I have some columns defined like this

<telerik1:GridViewMaskedTextBoxColumn Name="HistoryColumn4" DataFormatString="{}{0:n}"  MaskType="Numeric" Mask="n"  Header="{Binding Path=HistoryName4}" Background="LightGray" DataMemberBinding="{Binding Path=History4.Cost}" IsReadOnly="True" TextAlignment="Right"  IsFilterable="False" IsSortable="False" />

and some like this

                <telerik1:GridViewMaskedTextBoxColumn Name="BareDriveCostColumn" Header="Bare Drive Cost" DataMemberBinding="{Binding Path=Cost}" DataFormatString="{}{0:n}" TextAlignment="Right" MaskType="Numeric" Mask="n"  IsFilterable="False" IsSortable="False" >
                    <telerik1:GridViewMaskedTextBoxColumn.CellTemplate>
                        <DataTemplate>
                            <Grid MouseRightButtonDown="Cell_MouseRightButtonDown" DataContext="{Binding}"
                                  ToolTip="{DynamicResource toolTipTemplate}">
                                <TextBlock Text="{Binding Cost}"/>
                                <Border VerticalAlignment="Top" Width="5" Height="5" HorizontalAlignment="Right" Background="Red" Visibility="{Binding Comments,Converter={StaticResource MyConverter}}"/>
                            </Grid>
                        </DataTemplate>
                    </telerik1:GridViewMaskedTextBoxColumn.CellTemplate>                                    
                </telerik1:GridViewMaskedTextBoxColumn>

it errors on any of them.

Calculated Column refresh

All,

I have a calculated column in my grid. It works pretty fine but once I change one of the correspondig fields (Qt1...Qty18) the Total column doesn't update automatically. Is it supposed to calculate only once upon loading the grid or can I somehow accomplish to calculate on the fly once a depended column changes?

Thanks,
Lars

...
<telerik:GridViewExpressionColumn
                        Header="Total"
                        UniqueName="Total"
                        DataFormatString="{}{0:#,##0}"
                        />
...

In the constructor of the code behind I have the following lines:

    Expression<Func<ForecastInputItemViewModel, double>> expression = prod => prod.Qty1 + prod.Qty2 + prod.Qty3 + prod.Qty4 + prod.Qty5 + prod.Qty6 + prod.Qty7 + prod.Qty8 + prod.Qty9 + prod.Qty10 + prod.Qty11 + prod.Qty12 + prod.Qty13 + prod.Qty14 + prod.Qty15 + prod.Qty16 + prod.Qty17 + prod.Qty18;
            GridViewExpressionColumn column = ForecastGrid.Columns["Total"] as GridViewExpressionColumn;
            column.Expression = expression;

Simulate user delete row action programmatically

Hi,
a have a RadGridView with a bound ObservableCollection datacontext.
When the user selects a row and pushes the Delete key, the row disappears and the Deleted event is fired.
I have a menu item as well which allows to delete the selected row programmatically,
but when I call mygrid.Items.Remove(myselectedrow.DataContext) the row disappears, but the Deleted event is not triggered.
How can I get the grid to fire the Deleted event when removing a row programmatically as well?

Is it something like

mygrid.RaiseEvent(new RoutedEventArgs(RadGridViewEvents.DeleteRow, my_row));

?
Thank you,
Bye

[Solved] Aggregation function and Grouping

We have been using the GridView for a while now and we use Aggregation functions to let it calculate the totals. This works all fine.

The nice thing we can use grouping by default and get a total aggregation line as well Now here is the problems
The values on this line are not lined out with the original cells. Everything is lined to the left and looks very messy
Is there a solution to let these aggregation values be in the same column on these lines?
