1) Bind collection to GridView
2) Group on a column
3) set the collection to a new empty collection, or set grid itemssource = null

You should notice that the columns are still on the grid, but the group is removed.

We are trying to persist grouping options across different sets of data, when hitting an empty dataset, the grouping is lost.

The _Grouped and _Grouping events are not fired, however a manual check shows that the GroupDescriptors are indeed cleared.

(This is using Q3 Beta but it was the same behaviour in previous versions)

Hello,

I need to change the language of the localization of a gridview at runtime without creating an instance of a gridview (as shown in the examples). I know, that I have to adapt the templates for the RadGridView but before I start I wanted to ask whether there are any exisiting templates doing dynamic localization which could be provided or whether it is planned to support dynamic localization in a further Telerik version?

Kind regards,
Li

Hello,

I am maintaining some legacy code that runs Silverlight controls, deployed in a SharePoint 2013 web part.

I installed the latest version of 'Telerik UI for Silverlight'. I opened the project and notice that the Telerik references in my Silverlight project have successfully updated to the new version and the designers work fine.

The visual studio projects compile and deploy successfully, but when I go to the SharePoint page, I don't see the controls (in IE which is required for Silverlight).

When I debug the Silverlight code I get message: 

Could not load file or assembly 'Telerik.Windows.Controls, Version=2020.3.915.1050, Culture=neutral, PublicKeyToken=5803cfa389c90ce7' or one of its dependencies. The requested assembly version conflicts with what is already bound in the app domain or specified in the manifest. (Exception from HRESULT: 0x80131053).

What should I do to allow SharePoint to find these DLLs? I looked at the prod installation and none of the silverlight dlls (such as Telerik.Windows.Controls) were in the GAC and the application worked fine.

I appreciate any help you can offer.

Hi,

I got problem with SelectedItems binding - If I put breakpoint to the Setter of the SelectedComboFilterItems it will never be hit.

View:

<telerik:RadAutoCompleteBox x:Name="ComboFilterAutoCompleteBox" Grid.Column="1" Grid.Row="5"
  Margin="1" HorizontalAlignment="Stretch"   TextSearchMode="Contains"
  ScrollViewer.VerticalScrollBarVisibility="Auto"
  TextSearchPath="FormattedName" DisplayMemberPath="Name" SelectionMode="Multiple"
  ItemsSource="{Binding ComboFilterItems,Mode=TwoWay}"
  SelectedItems="{Binding SelectedComboFilterItems,Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
  IsEnabled="{Binding ComboFilterEnabled}"
  FilteringBehavior="{StaticResource CustomFilteringBehavior}"
   <telerik:RadAutoCompleteBox.DropDownItemTemplate>
                <DataTemplate>
                    <TextBlock Text="{Binding FormattedName}"/>
                </DataTemplate>
    </telerik:RadAutoCompleteBox.DropDownItemTemplate>
</telerik:RadAutoCompleteBox>

 

Here is ViewModel:

 

public ObservableCollection<DocumentType> mSelectedComboFilterItems = new ObservableCollection<DocumentType>();
public ObservableCollection<DocumentType> SelectedComboFilterItems
{
    get
    {
        return mSelectedComboFilterItems;
    }
    set
    {
        mSelectedComboFilterItems = value;
    }
}
public ObservableCollection<DocumentType> ComboFilterItems { get; set; } = new ObservableCollection<DocumentType>();

 

Rest of the binding is working fine.

If I select few items the SelectedComboFilterItems will hold those values. Just for some reason the setter is never called.

Cheers

Mike

Just to let you know, in the HtmlPlaceHolder Window Integration demo, if you have the zoom in IE to anything but 100%, the html is either too small or too big for the window, and misplaced.

Dear Telerik,

we have a serious problem using your report viewer for Silverlight. Presently all reports and graphics can only be printed out to locally connected printers. Printing to a networked printer does not work. The functions give the impression that the print process is running but at the end all that comes out of the networked printer is a blank sheet of paper. We have also discovered that the same is true of your online demo of the PDF-Viewer.

We need urgently your help in this matter.

With thanks in Advance.

Regards

Gina Siebrecht

Hi,

First I appologise I do not know which control this should belongs, hence I put this in general discussion.

I am looking for a control which can achieve the following:

- Freeze Column Header
- Freeze Column(s)
- Drill down on Column Header
- Drill down on Row

Attached is the example of report I would like to do in Silverlight.

Currently I know there is the Reporting Viewer, however it does not support Freezing on header. So I cannot choose this option.
The closest I found is the TreeVewList and the DataGrid. However both does not support drill on the header.

Please help and let me know any idea how to achieve this if possible.

Many thanks.

Hi,

 

I"m working with RadDiagram where I added several RadDiagramContainerShape and RadDiagramShape. The main container is a RadDiagramContainerShape and it is positioned at (0, 0) according to the RadDiagram.

 

When I click on the top left corner of the main container, at the red dot in the attached image, the button click is (41,39). Then I use PointToClient to get the position in the RadDiagram and I have (35, -40), knowing that it is supposed to be around (0, 0). Then to make sure of this I calculated the  PointToScreen using the main container location which is (0, 0). The result was (6, 79), but it is supposed to be around the button click (41,39).

 

In addition, when I drag and drop shapes to my main container it never goes to the cursor position because all what is mentioned above is not accurate.

 

Is this normal, and what can I do to fix this?

Thanks in advance for your help!
