Hi,

In my gridviewcolumns I can set a sortmemberpath and a groupmemberpath, what I'm missing is something like a FilterMemberPath.
Is it possible to implement this? This would be very helpful in a lookup value scenario.

Best regards,
Thomas.

Column Style?

Is there a way to either set the header to be vertical or to style a column in XAML. I have a old vb6 Flexgrid control that I need to replicate and I can do all of it in vb.net code -- but I wanted to style it to be grey(ghostwhite) and set the width and if possible define the static parts all in XAML and then just update the data parts in code

                    Private Sub BuildGrid(ByRef g As Telerik.Windows.Controls.RadGridView, ByRef d As IBIDData.Client)         
                    Dim dt As New DataTable(g.Name)         
                    dt.Columns.Add(0)         
                    dt.Columns.Add(1)         
                    Select Case g.Name

Using MDI RadWindows in xbap application

Hi,

I'd like to implement an MDI-like workspace in xbap application, is there any container for multiple RadWindows?

In my xbap application, I'd like the content-region would hold multiple RadWindows which can be dragged around, minimized, maximized, etc.

For dragging, I'd like it so that the windows themselves cannot be dragged outside of the mdi-window content region.

I'd appreciate any help/sample solution on how to implement this.

My xaml code is as follows:I have try to create MDI RadWindows in container1, but failed.

    
                    <telerik:RadDocking Name="radDocking1" Grid.Column="1" Grid.Row="1" AllowUnsafeMode="True">  
        
                        <telerik:RadDocking.DocumentHost> 
        
                            <telerik:RadSplitContainer InitialPosition="DockedLeft" Name="container1" HorizontalContentAlignment="Left">  
        
                                <telerik:RadPaneGroup Name="editGroup">  
        
                                </telerik:RadPaneGroup> 
        
                            </telerik:RadSplitContainer> 
        
                        </telerik:RadDocking.DocumentHost> 
        
                        <telerik:RadSplitContainer telerik:DockingPanel.InitialSize="150,150" InitialPosition="DockedBottom" Height="250">  
        
                            <telerik:RadPaneGroup Name="listGroup">  
        
                                <telerik:RadDocumentPane Title="Error Message" Name="errorMSGPane">  
        
                                    <telerik:RadDocumentPane.Content> 
        
                                        <TextBlock Name="tberrorMSG" Foreground="Red"> </TextBlock> 
        
                                    </telerik:RadDocumentPane.Content> 
        
                                </telerik:RadDocumentPane>                      
        
                            </telerik:RadPaneGroup>

                    </telerik:RadDocking>

Using column filter breaks RowEditEnded

Hello,

It looks like using a filter on one of my grid columns stops RowEditEnded from being invoked properly after the filtering.

I'm binding my grid to an ObservableCollection<> of business objects, and I have everything set up so updating/inserting rows works properly in most cases. However I've noticed that if I use a column filter and narrow down the rows displayed, for example to only those rows including certain text in that column, that any subsequent edits won't be saved because RowEditEnded no longer gets invoked when I finish editing one of the remaining rows.

Have you seen this behavior before? Is there something I'm doing wrong, or is this a known issue?

I can submit a ticket and provide a sample project if necessary.

Thanks for any help you can provide!

GridViewDataColumn: IDataErrorInfo awareness

                                <DataTemplate> 
        
                                    <TextBox Text="{Binding Path=Name, ValidatesOnDataErrors=True}" /> 
        
                                </DataTemplate> 
        
                            </telerik:GridViewColumn.CellTemplate> 
        
                        </telerik:GridViewColumn> 
        
                    </telerik:RadGridView.Columns>         
        
                </telerik:RadGridView> 
        
            </Window>

The second TextBox "Name 2" does show the DataErrors fine. However the GridViewDataColumn ("Name 1") seems unaware of the DataErrorInfos.

Am I missing something or is the GridVioewDataColumn unaware of IDataErrorInfo ?

Question: Virtualization and Column Header Caption Modification

Hello,

I've added some code to my grid's double click event so if a cell is double clicked the column header's caption will be appended with (*). The problem I having occurs when I scroll to the right and than double click the column caption is not modified. If I scroll to right a couple of times and than scroll back to where I double clicked the (*) appears in the column caption.

I am almost certain this is caused by Column Virtualization. Is their anyway to fix this so the (*) appears after I've double clicked?

Thanks

I'm binding a IList<BusinessObject> to the GridViewDataColumn through a converter.
Code snippet:

                          <telerik:GridViewDataColumn
                                                        Header="Classes"
                                                        Width="15*"
                                                        UniqueName="AuthorisationClasses"
                                                        DataMemberBinding="{Binding AuthorisationClasses, Converter={StaticResource AuthorisationClassesListConverter}}"

The view gets updated dynamically if I make the AuthorisationClasses an ObservableCollection. I was wondering if I could make the view update dynamically without making it an ObservableCollection. The reason being, AuthorisationClasses is a business entity and all the business entites in our solution are of type List<T>.
Thanks in advance
