RadGridView background brush does not update

Hi,

We are using the 2011.1.315.40 version of the WPF libraries.

We have a custom style defined for the RadGridView, and for the background color, we are using a defined brush in another resource dictionary (set as a dynamic resource). From the RadGridView style:

<Setter x:Uid="Setter_302" Property="Background" Value="{DynamicResource TestListBackgroundBrush}"/>

ListBackgroundBrush is defined in two resource dictionaries, with two different values - one for each theme offered by the application. When changing theme, we unload one resource dictionary and load the other.

However, for any RadGridView controls that have already been displayed, the background color does not change. Checking the resources loaded shows that the value with that key has indeed changed - it is just that the RadGridView does not update.

This is strange as the RowStyle for the grid view also has its background set to use this brush (also DynamicResource) and that color does change correctly.

Can you please suggest what could be happening here. It is not an option for use to upgrade to a more recent version of the library.

Thanks.

RadComboBox Isenabled not working

Hello,

I have the following RadCombo Box:

<telerik:RadComboBox x:Name="Combo" Grid.Column="2" Grid.ColumnSpan="4" Grid.Row="0"
VerticalAlignment="Center"
IsEnabled="False"
ItemsSource="{Binding MyList}"
SelectedItem="{Binding selectedItem, Mode=OneWay}"
ItemTemplate="{StaticResource ComboBoxTemplate}"
Command="{Binding SelectedCommand}"
CommandParameter="{Binding Path=SelectedItem, ElementName=Combo }"
/>

Setting IsEnabled to false does not effect the combo box at tall.

If I removed the Command and CommandParameter from the RadComboBox then the IsEnabled Property works as expected.

Is there a way / fix / workaround is use the isenabled property when also using a Command / Command Parameter

Many Thanks

Extending RadTreeView & RadTreeViewItem

Hi,

Purpose: extending the RadTreeView & RadTreeViewItem
In order to immplement the purpose above i had to inherit the both classes.
When i binding the NewRadTreeView ItemSource to viewmodel
i found the previous RadTreeViewItem instead NewRadTreeViewItem.

In order to use my NewRadTreeViewItem i did the override below in NewRadTreeView & NewRadTreeViewItem:
protected override DependencyObject GetContainerForItemOverride()
{
    var rti = base.GetContainerForItemOverride();
    if(rti is RadTreeViewItem)
    {
        rti = new NewRadTreeView();
    }
}

I wonder if i'll have to expect for other things that might affect?
What about the AddItem, Next, Previous etc...?

Best regards

RadDocking chart repaints lines on redock

Hi,

I am using RadDocking to redock my RadCartesianChart in a window. However when I redock on drop the chart lines get redrawn. I have attached images of before and after this occurs. I am wondering what is causing this behaviour? It seems to redraw every time the chart is redocked in the window.

Any suggestions would be great.

Thanks,
Adam

Expand to show new added items

Hi

I have a tree structure that's mirrored in a viewmodel structure - there's various event handlers in a 'wrapper' collection that monitor the tree structure for items added and removed and creates and removes corresponding viewmodels.

When a viewmodel is added, it appears in the TreeListView as expected.

Is there any way I can expand and select a 'new' item?

I know I can bind selected items and IsExpanded, but from my description you might see that I don't have the viewmodel when the model is changed - this is done automatically. I thought I'd see if anyone had a better idea before I go down that route.

Thanks!
