How do I initiate a sort from code?

I want to initiate sort on the grid from code. I am not having success.

This is what I've tried:

gvDocumentListing.Columns[4].SortingState = Telerik.Windows.Controls.SortingState.Descending;

gvDocumentListing.Rebind();

This does not work. I saw in an earlier post that some one called Columns.Reset(). This method appears to have been removed.

Determine row an column of an item

Is there a way to determine the actual position of a RadTileViewItem in a RadTileView? Something like
RadTileView.GetPosition(RadTileViewItem item, out int row, out int column)?

Thanks,
Michael

Multiple notifications when item is checked

Hi,

I've created a treeview which has the TriStateMode enabled and defined a callback function when an item were checked/unchecked.

My problem is that I get notified multiple times if a subitem was checked. The first notification is for the top element, and the next notification is for the top level's child element and so on... The last notification is the checked item itself.

Is there a way to determine the item which was checked?

Thanks
Dieter

[Solved] Strange behaviour on vertical scrolling

I have a gridview, using version 2009.3.1208.35 and MVVM. Style and visibility is applied like the following:

                            <telerik:RadGridView.Resources>         
                        <Style TargetType="{x:Type GridView:GridViewRow}">         
                            <Setter Property="Background" Value="#FFFFe1" />         
                            <Style.Triggers>         
                                <DataTrigger Binding="{Binding Path=OperationId}" Value="0">         
                                    <DataTrigger.Setters>         
                                        <Setter Property="Background" Value="#FFFFFF" />         
                                    </DataTrigger.Setters>         
                                </DataTrigger>         
                                <DataTrigger Binding="{Binding Path=OperationStatus}" Value="9">         
                                    <DataTrigger.Setters>         
                                        <Setter Property="Visibility" Value="Collapsed" />         
                                    </DataTrigger.Setters>         
                                </DataTrigger>         
                            </Style.Triggers>         
                        </Style>         
                    </telerik:RadGridView.Resources>         
                     

Everything looks fine when the grid is loaded, but, if I scroll vertically, it seems like <Setter Property="Visibility" Value="Collapsed" /> doesn't work anymore. No more rows are collapsed. Is this is a bug, or am I missing something?

Shrink Column Width

Hello,

The column of my grid is set to SizeToContent, which of course causes my column size to increase to the size of the lengthiest data in the column, which is great. When the row is removed, however, the column remains at that extended size. I would like to be able to have my column automatically "snap back" to the next lengthiest bit of data remaining in the grid, but have been unable to find a way to accomplish this with any of the existing properties. Is there a way to accomplish this kind of behaviour I'm missing?

Thanks,

Dave

TabControl with Custom ContentTemplate not redrawing

I have a RadTabControl with a Custom ContentTemplate. It works fine, and displays the content as I'd expect when first viewing the tab. However, when changing from one tab, back to the original tab, I find that the data inside the content presenter is no longer being displayed. It appears as if the DataContext or ItemsSource binding is no longer being applied as I'd expect.

Below is a short expample which should illustrade what I'm seeing. I'm using MVVM, and the ClosedOrderCol in the code snippet below is an ObservableCollection on the ViewModel.

Any help would be appreciated.

    
            <Navigation:RadTabControl> 
        
                        <Navigation:RadTabControl.ItemContainerStyle> 
        
                                <Setter Property="ContentTemplate"> 
        
                                    <Setter.Value> 
        
                                        <DataTemplate>

                                            <Grid> 
        
                                               <ContentPresenter Content="{TemplateBinding Content}"/>

                                            </Grid>

                                        </DataTemplate> 
        
                                    </Setter.Value> 
        
                                </Setter> 
        
                        </Navigation:RadTabControl.ItemContainerStyle> 
        
                        <Navigation:RadTabItem> 
        
                                <Controls:RadGridView Grid.Row="1" ItemsSource="{Binding ClosedOrderCol}" IsReadOnly="True"> 
        
                                    <Controls:RadGridView.Columns>                        
        
                                       <Controls:GridViewDataColumn Header="Closed" DataMemberBinding="{Binding DateClosed}" /> 
        
                                    </Controls:RadGridView> 
        
                        </Navigation:RadTabItem> 
        
                        <Navigation:RadTabItem /> 
        
            <Navigation:RadTabControl>
