Hi,

I am trying to bind dictionary object to ListBoxControl as shown below

<telerik:RadListBox ItemsSource="{Binding Path=BooksAvailable}" Height="270">
<telerik:RadListBox.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<CheckBox IsChecked="{Binding Path=Value}"
Width="20" />
<TextBlock Text="{Binding Path=Key}"
Width="100" />
</StackPanel>
</DataTemplate>
</telerik:RadListBox.ItemTemplate>
</telerik:RadListBox>

I want to do two way binding of the values so that if user unchecked I have to update internal Boolean value property.But it is giving exception two way binding can't be possible with dictionary value.

Please help to resolve this.

Regards,

Nagasree.

Excel-style Delete key behavior in GridView

Is there any way to implement Excel-style "Delete" key behavior for selected cells in RadGridView? I want the Delete key to clear the selected cell's contents, setting the underlying data-bound property value to null or whatever the default value of the databound type is.
I haven't been able to find any info on whether this is possible-- somebody posted a related issue in 2010 (http://www.telerik.com/forums/cleaar-the-cell-content-at-runtime) but it does not appear to have been resolved.
Could someone please help me implement this behavior? I'm currently trying to override the delete key in a custom KeyboardCommandProvider but none of the RadGridViewCommand options do what I want.

Spinner won't show on grouping, sorting and filtering

Hey telerik,

My grid's external spinner (RadBusyIndicator) won't work when grouping the grid. It works only when loading data.

Here is some sample code illustrating my scenario:

<telerik:RadBusyIndicator Name="busyIndicator" IsBusy="True" DisplayAfter="0">

<telerik:RadGridView Name="RadGridView" ItemsSource="{Binding View}" IsReadOnly="True" Style="{StaticResource VitorStyle}" AutoGenerateColumns="False">

private void Window_Loaded(object sender, RoutedEventArgs e)

{

((ViewModel)DataContext).Load(complete);

var view = (DataContext as ViewModel).View;

view.ItemsLoading += View_ItemsLoading;

view.ItemsLoaded += View_ItemsLoaded;

//the spinner wont work for the grouping.

//this.RadGridView.Grouping += RadGridView_Grouping;

//this.RadGridView.Grouped += RadGridView_Grouped;

//this.RadGridView.GroupRowIsExpandedChanging += RadGridView_GroupRowIsExpandedChanging;

//this.RadGridView.GroupRowIsExpandedChanged += RadGridView_GroupRowIsExpandedChanged;

}

//private void RadGridView_GroupRowIsExpandedChanged(object sender, Telerik.Windows.Controls.GridView.GroupRowEventArgs e)

//{

// this.busyIndicator.IsBusy = false;

//}

//private void RadGridView_GroupRowIsExpandedChanging(object sender, Telerik.Windows.Controls.GridView.GroupRowCancelEventArgs e)

//{

// this.busyIndicator.IsBusy = true;

//}

//private void RadGridView_Grouped(object sender, GridViewGroupedEventArgs e)

//{

// this.busyIndicator.IsBusy = false;

//}

//private void RadGridView_Grouping(object sender, GridViewGroupingEventArgs e)

//{

// this.busyIndicator.IsBusy = true;

//}

//B)

private void View_ItemsLoading(object sender, VirtualQueryableCollectionViewItemsLoadingEventArgs e)

{

this.busyIndicator.IsBusy = true;

}

private void View_ItemsLoaded(object sender, VirtualQueryableCollectionViewItemsLoadedEventArgs e)

{

this.busyIndicator.IsBusy = false;

}

public class ViewModel

{

public VirtualQueryableCollectionView View { get; set; }

Controller controller;

public ViewModel()

{

controller = new Controller();

}

public void Load(bool complete)

{

//G the virtual queryable collection. this is the Key Class telerik grid needs to perform the Infinite scrolling. or virtualization.

View = new VirtualQueryableCollectionView(controller.GetList(complete)) { LoadSize = 10 };

}

This spinning issue has been troubling me for quite some time by now.

It won't show on grouping, sorting and filtering.

please send a light

Thank you!

Problem with scroll after save and NewRowPosition definition

Hi,

RadGridView behavior after update/insert row is different between NewRowPosition="Top" and NewRowPosition="Bottom".
When position is defined "top", after saving the scroll is on the same position as before saving. However, when the position is defined "Bottom", after saving it scrolls to top.
Workaround with ScrollIntoView() is not useful in my case, because I may have many rows updated.
How can I achieve the same behaviour as NewRowPosition="Top" after saving?

Thanks
