When using the GridView. If the first thing I click on in the grid is the left panel where the selection/insertion indicator is and hit the Insert Button it doesn't work until I click for a 2nd time. After that it works every time. Do you have a workaround for this as it is a bit clunky usabilitywise?

Selected Item is always the type of item

Hello

I am filling a the items of the RadComboBox in the code behind.

    
                        foreach (LJSDataSet.LJ_DBRow row in dbNew.LJ_DB.Rows)  
        
                        {  
        
                            StackPanel pan = new StackPanel();  
        
                            TextBlock tb1 = new TextBlock();  
        
                            TextBlock tb2 = new TextBlock();  
        
                            tb1.Width = 130;  
        
                            tb1.Text = row.DBNAME;  
        
                            tb2.Width = 90;  
        
                            tb2.Text = row.DBSERV;  
        
                            pan.Orientation = Orientation.Horizontal;  
        
                            pan.Children.Add(tb1);  
        
                            pan.Children.Add(tb2);  
        
                            this.comboDB.Items.Add(pan);  
        
                        }

When I compile the project, the combobox items are displayed as expected. But the SeletedItem always shows the type name
System.Windows.Contols.StackPanel.

How can I avoid this?

Thank you in advance.

Save and Restore all the grid settings?

I have a few grids, for which user can sort, filter, group and reorder columns. Also user can choose what are all columns he/she need to view in grid. All sort, filter, grouping and reordering are done by default, and i did visibility functionality by providing interface like add/remove columns, where user can choose hidden columns to show and visible columns to hide. After this selection i am setting IsVisible property of Grid.Columns in a loop.
Now I need to store all these settings per user basis in database and should load with the same state whenever he returns. Can I have any sample code to achieve this?

Change the font of the calendar within RadDatePicker

I've got a RadDatePicker, and I'd like to be able to set the font of the days within the calendar, but can't find an obvious way of doing so.

Here's some code I tried:

    
                    <telerik:RadDatePicker Grid.Row="4" Grid.Column="1" Name="DatePlanned"  
        
                                           SelectedDate="{Binding SelectedDatePlanned, Mode=TwoWay}" > 
        
                        <telerik:RadDatePicker.MonthViewStyle> 
        
                            <Style> 
        
                                <Setter Property="Control.FontSize" Value="16" /> 
        
                            </Style> 
        
                        </telerik:RadDatePicker.MonthViewStyle> 
        
                    </telerik:RadDatePicker>

How can I accomplish this?

RadScheduler disable Drag'n'Drop

Hi,

it seems the RadScheduler's drag 'n' drop behaviour has changed.
Inside my AppointmentTemplates for the Day-View I have a lot of "custom" drag 'n' drop functionality (and scrollviewers) which was no problem before.
But with the beta the RadGridView's own Drag'n'Drop starts immediately and tries to move the appointment.

How can I disable the drag'n'drop? Or maybe there is another solution.

Best Regards
Steffen
