Export RadGridViewto excel with a column with CheckBox

Hi everybody!

I was working with the RadGridView control in the Telerik version 2009.2.701.35 and for some reasons we can not use newer version. We have been some time working on a way to export the values of a column (that we represent with checkboxes, even in the header) to excel.

As obvious, it can not handle directly the checkboxes and it left the spaces without value. We need to know if it is possible to set the value before the exporting time as I read it was possible for ASP.

Any idea?

Thanks in advance.

Drag ItemTemplate only text

I have been attempting to incorporate the Drag and Drop example for two listBoxes. Yet, when i drag my item it just shows the text and not the item template from the listBox. I have included a image to show what i am talking about...

private void OnDragInfo(object sender, DragDropEventArgs e)

{

if (e.Options.Status == DragStatus.DragComplete)

{

var listBox = e.Options.Source.FindItemsConrolParent() as ItemsControl;

var itemsSource = listBox.ItemsSource as IList;

var operation = e.Options.Payload as DragDropOperation;

itemsSource.Remove(operation.Payload);

}

private void OnDropInfo(object sender, DragDropEventArgs e)

{

var destination = e.Options.Destination;

if (e.Options.Status == DragStatus.DropPossible && destination is ListBoxItem)

{

var listBox = destination.FindItemsConrolParent() as ListBox;

FrameworkElement rootChild = VisualTreeHelper.GetChild(listBox, 0) as FrameworkElement;

Storyboard dropStoryboard = rootChild.FindResource("DropStoryboard") as Storyboard;

dropStoryboard.Begin();

//Get the DropCueElemet:

var dropCueElement = (VisualTreeHelper.GetChild(listBox, 0) as FrameworkElement).FindName("DropCueElement") as FrameworkElement;

var operation = e.Options.Payload as DragDropOperation;

//Get the parent of the destination:

var visParent = VisualTreeHelper.GetParent(destination) as UIElement;

//Get the spacial relation between the destination and its parent:

var destinationStackTopLeft = destination.TransformToVisual(visParent).Transform(new Point());

var yTranslateValue = operation.DropPosition == DropPosition.Before ? destinationStackTopLeft.Y : destinationStackTopLeft.Y + destination.ActualHeight;

dropCueElement.RenderTransform = new TranslateTransform() { Y = yTranslateValue };

e.Handled = true;

}

if (e.Options.Status == DragStatus.DropPossible && destination is ListBox)

{

var listBox = destination as ListBox;

FrameworkElement rootChild = VisualTreeHelper.GetChild(listBox, 0) as FrameworkElement;

Storyboard dropStoryboard = rootChild.FindResource("DropStoryboard") as Storyboard;

dropStoryboard.Begin();

//Get the DropCueElemet:

var dropCueElement = (VisualTreeHelper.GetChild(listBox, 0) as FrameworkElement).FindName("DropCueElement") as FrameworkElement;

var operation = e.Options.Payload as DragDropOperation;

// Get the size of the items:

var itemsPresenter = listBox.GetTemplateChild<FrameworkElement>("ItemsPresenterElement");

var panel = VisualTreeHelper.GetChild(itemsPresenter, 0) as Panel;

if (panel != null)

{

var yTranslateValue = panel.ActualHeight;

dropCueElement.RenderTransform = new TranslateTransform() { Y = yTranslateValue };

}

//Hide the DropCue:

if

(e.Options.Status == DragStatus.DropImpossible || e.Options.Status == DragStatus.DropCancel || e.Options.Status == DragStatus.DropComplete)

{

var listBox = destination as ListBox;

if (listBox == null)

}

FrameworkElement rootChild = VisualTreeHelper.GetChild(listBox, 0) as FrameworkElement;

}

//Place the item:

var destinationIndex = itemsSource.IndexOf(e.Options.Destination.DataContext);

var operation = e.Options.Payload as DragDropOperation;

any help would be great... im still relatively new to the WPF game... i apologize in advance...

Bug in internal build: 2010.3.1331.40

Hi, we're getting this exception when updating to v. 2010.3.1331.40 in the RadGridView control:

System.Reflection.TargetInvocationException was unhandled
Message=Property accessor 'C' on object 'RadControlsWpfApp2.A' threw the following exception:'Object does not match target type.'

It seems like the problem is related to the number of sublevels in the DataMemberBinding. In the example below the binding of the first column works, but the second column fails.

To recreate the exception:

<Window x:Class="RadControlsWpfApp2.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

        {
            InitializeComponent();
            var model = new Model();
            DataContext = model;
        }
    }
}

using System.Collections.Generic;
 
namespace RadControlsWpfApp2
{
    class Model
    {
        public Model()
        {
            Items = new List<A> {new A(), new A()};
        }
        public IList<A> Items { get; set; }
    }
 
    class A
    {
        public A()
        {
            B = new B();
        }
        public B B { get; set; }
    }
    class B
    {
        public B()
        {
            C = new C();
            Id = "3213123";
        }

        public C()
        {
            Name = "Test";

Setting ItemSource to null

After I've updated to latest version, I've recieved a null reference exception when I was setting the RadGridView's ItemSource to null.
I've rolled back to the previous version of Telerik Controls and it is back to normal. Could you check the new version for a possible bug?

Blinking

Simple code:

</telerik:RadTabItem>

</telerik:RadTabControl>

</Grid>

</Window>

The main window is blinking when you switch between tabs repeatedly. Sometimes window even disappear/hides.

Styling a Databound menu

Hi,

Please excuse my ignorance but I'm just beginning to do battle with WPF styling / Templates etc.

I'm trying to style up a RadMenu that is databound and uses the HierarchicalDataTemplate. I'd like to have the header row menu items styled differently to the child items, including font sizes, mouseover colors / animations etc. The examples contained in the documentation seem to be very limited, showing only the most basic of style setters and no examples of selecting different styles based on the type of menu item (header item or child). Can anyone provide me with a more complete example of radically changing the styling of a RadMenu as described above?

Many thanks

Mat
