Hi,
I have two checkboxs that, when checked, apply or remove custom filters.  The filters work fine (mostly), only problem is that the first time FilterDescriptors.Clear(); is called all the rows in the grid dissapear.  On any subsequent calls it works as expected.
 
Both checkboxes call the following method:  

#region private void HandleCheckBoxFilters()

private void HandleCheckBoxFilters()

{

    bool? PaidInFullChecked = CheckBox_PaidInFull.IsChecked;

    bool? Show60PaymentsOnlyChecked = CheckBox_FixedAmount.IsChecked;

 

    //RadGridView_TrusteeLedgers.FilterDescriptors.Clear();

 

    CompositeFilterDescriptor compositeDescriptor = new CompositeFilterDescriptor();

    compositeDescriptor.LogicalOperator = FilterCompositionLogicalOperator.And;

 

    RadGridView_TrusteeLedgers.FilterDescriptors.Clear();

 

    if (PaidInFullChecked == true)

    {

        FilterDescriptor filterDescriptor_PaidInFull = new FilterDescriptor();

        filterDescriptor_PaidInFull.Member = "PaidInFull";

        filterDescriptor_PaidInFull.Operator = FilterOperator.IsEqualTo;

        filterDescriptor_PaidInFull.Value = true;

        filterDescriptor_PaidInFull.IsCaseSensitive = false;

 

        compositeDescriptor.FilterDescriptors.Add(filterDescriptor_PaidInFull);

    }

 

 

    if (Show60PaymentsOnlyChecked == true)

    {

        FilterDescriptor filterDescriptor_FixedAmount = new FilterDescriptor();

        filterDescriptor_FixedAmount.Member = "TotalRemaining";

        filterDescriptor_FixedAmount.Operator = FilterOperator.IsEqualTo;

        filterDescriptor_FixedAmount.Value = Convert.ToDecimal(60);

        filterDescriptor_FixedAmount.IsCaseSensitive = false;

 

        compositeDescriptor.FilterDescriptors.Add(filterDescriptor_FixedAmount);

    }

 

    RadGridView_TrusteeLedgers.FilterDescriptors.Add(compositeDescriptor);

 

}

#endregion

I am using a RadGridView where the ItemsSource is bound to a QueryableCollectionView that contains a RadObservableCollection of data.  The data is loaded asynchronously from a web service, so on return from the service, the collection is updated by calling Clear, then AddRange, and then Refresh is called on the QueryableCollectionView.

This was working great until we applied the hotfix from 9/27 which we needed to fix another issue in the rich text editor.  Once we applied the hotfix, the grid would not display any data in the rows, but would recognize the correct amount of data rows.  The grid also does not display any filter buttons in the headers, and there is no change to the header state when sort is applied.  I can see my data in the collection, but the grid won't display the cell contents.

This is also not working in the 9/20 build, but works fine in the 7/12 build and previous.

I cannot reproduce the problem by making synchronous calls to load data.  This only happens when the Refresh is applied after a callback.

Thanks for any help.

Edit:  Any columns where we override CreateCellElement are working.  GridViewDataColumn without the override is not working.

Hi,

We are using GridViewSelectColumn in our TreelistView and each time when data loaded the first item in the list selected(check box is checked). Is it default behavior if not how to turn off this behavior ?

Thank you,

Hi,

I there an easy way to hide/disable the left/top/right/botttom indicators on the RootCompass ?
I need to:
1.  avoid users from docking on the outer edges of the RadDocking area
2. only allow docking on the RadPaneGroup (left/top/right/botttom) within the RadDocking

I know how to enable/disable left/top/right/botttom indicators on the Compass, but I don't know how to do this on the RootCompass

Please advice...

Hello,

in my simple example i have a RadPanelBar with three RadPanelBarItems.
The default behavior of the items is to expand on selection. This is fine for me.

Now I want the user to confirm the change of the selection of the RadPanelBarItems.
Therefore I use a MessageBox in the PreviewSelectionChanged event of the RadPanelBar.

The confirmation logic works fine but the selected item is not expanded after confirmation.
This behavior is different to the default.

Regards
Rainer

The sample code:

For an application on which I'm working, I want to export all appointments from a ScheduleView to an ICalendar format.  By following the ICal example provided in the  WPF Q2 2011 Demos, I have been able to successfully export all of my appointments using the AppointmentCalendarExporter.  

My next step was to create some exceptions to a recurring appointment, and try to export those.  This is where I ran into some problems.  If I create an exception which simply excludes an occurrence of a recurring appointment, then I can still export the recurring appointment to an ICalendar format (file or string), and the exclusion is represented in the ICal content like so:  "EXDATE:20110923T050000".  However, if I create an exception in which I change the time of an occurrrence of a recurring appointment (per the example here), then attempting to export the appointment to an ICal format results in a StackOverflowException.

Any idea what's going on here?

I have previously used RadDock in Telerik Winforms. When adding a dock window it had context menu options such as close, close all but this, close all, New Horizontal Tab Group.

Also on the right hand corner of the raddock, there was a dropdown with a list of all open document windows.

Are these features available in WPF docking?

Hi

Hi, I am using RadControls for WPF (Q2 2011), in particular the GridView control. I am aware this control includes a cool looking dialog for filtering the data for each column however due to the fact I am trying to implement custom paging using Entity Framework I would also like to customise the look of the filter dialog, is this possible and if so please explain how.

I'd like to keep the section whereby one is able to filter the results by text search etc. but I don’t want to display the top section allowing the user to select the specific items in the collection. Hope that makes sense, I would send a screen shot however I don’t think its possible here??

Thanks in advance
