Hi,

I have recently been working with the RadMaskedTextBox control and noticed it has a cool IsSpinEnabled property to enable the mouse wheel to scroll up/down the date value.

I immediatly went to enable it in the DatePicker controls I am using, but it doesn't exist. Is it named something different in the DatePicker's?
There doesn't appear to be any DatePicker documentation either for WPF or Silverlight (at least in the online version), so I couldn't check myself.

Thanks,

A Marshall

Column rendering in inherited grid.

On inheriting from "RadGridView" and overriding the "OnApplyTemplate" the only the first column is rendered.

    
            namespace WpfApplication7 
        
            { 
        
                public class  MyGrid : RadGridView 
        
                { 
        
                    public override void OnApplyTemplate() 
        
                    { 
        
                        //Custom Code. 
        
                    } 
        
                } 
        
            }

    
            <Window x:Class="WpfApplication7.Window1" 
        
                xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

                xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
        
                Title="Window1" Height="300" Width="300"> 
        
                <Grid> 
        
                    <local:MyGrid>

Problem with a custom collection implementing INotifyCollectionChanged

hi,

I have a generic collection implementing INotifyCollectionChanged with an Add method as the following:

    
            public void Add(TEntityType item)  
        
                    {  
        
                        if (Criteria(item))  
        
                        {  
        
                            InnerList.Add(item);  
        
                            CollectionChanged(InnerList, new NotifyCollectionChangedEventArgs(NotifyCollectionChangedAction.Add, item));  
        
                            if (SelectAddedItem) CurrentItem = item;  
        
                        }  
        
                    }

and it works fine with framework's ListView and DataGrid components with a binding to its ItemsSource property.

But RadGridView does not updates itself with "NotifyCollectionChangedAction.Add" but it works fine with "NotifyCollectionChangedAction.Reset". Am I doing something wrong ?

Chaning collor behind Tabs

Hello All,

I want to change that gray collor *behind* the tabs themselves to lets say Transparent. I'm not taking about the color behind the content or the background color inside the tab. I'm talking about the color behind the tab collection themselves. How do I do that?

In addition, how do I change the background color of the *non-active* tabs from that off-white color?

3D Chart -> Export behaviour

Dear Telerik,

Thank you for the export option, but I have two questions:

1. When exporting to png/bmp, the background is not exported,
    instead, a 32bit BMP, or a transparent PNG is created.

    Is there a solution for this problem?

2. We can enter a dpi in the export option, but my problem is sometimes
    the user interface is very small, and so is the chart,
    Would be great if we can supply a Width/Height of the exported chart.

With regards,
Rob

Drag and Drop

I am using the grid as the source for my drag and drop in the RadDragAndDropManager. I have one small issue and that is when I have a selected item in the grid and try to drag the scrollbar, it initiates the drag of the selected item. How can I detect what part of the grid is under a specifc point? I was planning on using the MouseClickPoint of the drag event args.

Thanks,
David Ribb
