Hi

We have a problem with ContextMenu in a textbox when we try to use it inside a DataFormDataField, the items doesn't appears, just appear "Copy, Cut, Paste".
We did try populate the ItemsSource property from Opening Event and from a Binding, but doesn´t work
I attached a little example solution

And here some code, the textbox outside DataForm works perfect

Thanks in advance

Hello,

I am trying to use the CloudUpload within an ElementHost. When I choose a file and then click upload I get the following error:

Object reference not set to an instance of an object.
   at Telerik.Windows.Cloud.Controls.Upload.CloudUploadFile.UpdateCommandsCanExecute()
   at Telerik.Windows.Cloud.Controls.Upload.CloudUploadFile.SetState(CloudUploadFileState value)
   at Telerik.Windows.Cloud.Controls.Upload.CloudUploadFile.StartUpload()
   at Telerik.Windows.Cloud.Controls.RadCloudUpload.StartUpload(IEnumerable`1 items)
   ...

I'm setting up the CloudUpload like so:

            var upload = new RadCloudUpload();
            upload.Name = "radCloud1";
            upload.Provider = new DummyProvider();
            elementHost1.Child = upload;
 
 To confirm that I wasn't setting it up incorrectly I tried the same code without the element host and it works fine. Is the ElementHost unsupported?

I want to put some text in the footer of a column in my gridview. However I can't get the binding to work.

 

I'm using MVVM. I have one viewmodel for the whole form including the gridview (let's call this MainViewModel) and also one viewmodel per row in the gridview (RowViewModel).

 

The text I want to show in the footer is in MainViewModel (let's call the property FooterText). How can I bind the text of the footer to this property?

 

My footer looks like this:

This example works and displays the text "Testing" in the footer. But my problems starts when I try to set the text using binding instead.

 

This doesn't work:

I didn't expect this to work since all other properties of the column gets bound to the RowViewModel and not the MainViewModel. I'm guessing the same goes for the footer.

 

I've tried this:

LayoutRoot is the Grid that is the root element of the form that the gridview resides in. This does not work. What confuses me is that I can bind the Header of the column in the exact way and it works:

 

I've also tried this:

This didn't work neither.

 

Any more ideas?

When I have the following in my XAML code:



If I change AreWeekNumbersVisible to True, it works just fine. I am using telerik version 2013.3.1204.45.

See attached images.

I'm using Telerik DocumentSpellChecker together with a RadRichtextBox in a WPF-Application .

How do I do a case insensitive word comparison???

Is it possible to use a ChartSeriesProvider with a CompositeCollection as the Source? Just specifying one as a StaticResource (which works fine for something like a ListBox that uses ItemsSource) results in an exception:
    Could not find property 'SeriesType' for type 'System.Windows.Data.CollectionContainer'

And the ViewModel:

Hi there. I am using a dataform to allow updates to a small class that contains a numeric value (specifically a decimal type).  The autogenerated field for the variable doesn't seem to be permitting me to input a decimal point. 

Any thoughts?

Hi,

I am trying to display current time with an annotation, but it gets missplaced when the vertical scrollbar is shown (see screenshots).

I think the reason for the issue is that the VirtualizingTimelinePanel for annotation occupies the whole radtimeline width while the VirtualizingTimelinePanel for items is shrink by the ScrollViewer.

I am using the Windows8 theme.

Is this a known issue? Is there a workaround for it?

Best,

Ola

During our evaluation of the RadMap control, we noticed that there is a significant delay (almost 1 second) between the mouse dragging and the starting of map panning.

I am using a local single image provider, so loading time shouldn't be the issue.

Is there any parameter I need to set to reduce this delay.

Is there a way to change the background of the last column in GridView (attached image)

I have to display different number of columns based on some properties so i can not use Data binding, I ma creating the columns in code behind and also setting the width of columns.
In order to not have the last blank column i tried to set the width of last column to *, but when i do that the horizontal scroll bar do not appear if the content in the rows is bigger than the view can display

Here is the code i am using
/// <summary>
        /// Create the grid based on the list type
        /// </summary>
        private void InitializeGrid(csEnumListType listType)
        { 
            switch (listType)
            {
                case csEnumListType.csLstAppointmentTypes:
                    AddColumn("Description", 250, "GridDescription");
                    AddColumn("Abbreviation", 100, "ColumnValue1");
                    AddColumn("Appointment Category", 100, "ColumnValue2", true);
                    break;                
                case csEnumListType.csLstCollectors:
                case csEnumListType.csLstOperators:
                    AddColumn("Name", 400, "GridDescription");                    
                    AddColumn("Abbreviation", 85, "ColumnValue1", true);
                    break;
                case csEnumListType.csLstClmStyles:
                    AddColumn("Description", 300, "GridDescription");
                    AddColumn("Abbreviation", 100, "ColumnValue1");
                    AddColumn("Billing Media", 85, "ColumnValue2");
                    AddColumn("Claim Format", 100, "ColumnValue3", true, true);
                    break;
                default:
                    AddColumn("Description", 300, "GridDescription");
                    AddColumn("Abbreviation", 100, "ColumnValue1", true);                    
                    break;
            }            
        }
