[Solved] Prevent focus when ScrollIntoView

Hello

I am building a windows application using the MVVM pattern.

My scenario is as following:
I have a window with several viewmodels in it.

(VM1) Viewmodel containing a list of items displayed through it's view with the help of RadGridView.

(VM2) Viewmodel with a search-like function, given a search criteria it sets the SelectedItem in VM1.

My first problem was that the selecteditem could be out of view. I made a mvvm-exception and added code behind and used ScrollIntoView to solve that problem (works like a charm).

    
            private void SelectionChangedHandler(object sender, Telerik.Windows.Controls.SelectionChangeEventArgs e)  
        
            {  
        
               if (this.radGridView.SelectedItem != null)  
        
               {  
        
                    this.radGridView.ScrollIntoView(radGridView.SelectedItem);  
        
               }  
        
            }

My problem now is that when scrolling occurs, the RadGridView gains focus. Is there any way to prevent this?

Best regards and thanks.
Thomas

Request: FilterMemberPath

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)

[Solved] 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>

[Solved] 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!

                        </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

WPF Demo Crashes while browsing around

Hello, I just installed the demo. It seems to work fine when I click on an item on the tree list but when I click on another item on the tree list, it crashes. It always crashes when I select my second item but the first item loads fine.

Here's a screenshot: http://img291.imageshack.us/img291/7963/crashwi6.jpg
