Hi, I am binding a Dataset to a RadGridView, but I am getting some strange behaviors. I already try to bind the dataset, datatable or default table view. Same Result.
Other problem is when my datatable has no rows (only columns defined). Nothing is displayed, even the column itself.

I had attached some images to show what´s happen.

Thanks

I have a RadGridView where on of the columns is a GridViewComboBoxColumn.

How do I sort the Items inside the the RadComboBoxs alphabetically?

Assume I have three cities: Manchester, Zurich and Aberdeen. I want my RadComboboxes to display alpabetically

Aberdeen
Manchester
Zurich

The underlying data is rather big: There are some ten-thousands of grid-rows and the items inside the RadComboBoxes can also be some ten-thousands (RadCombox items are city names). Thanks to virtualization the performance is actually very good.

I don't want to sort each single ComboBox, since this might slow down the Grid considerably. 
I found documentation and some forum posts about SortingState, but that was not helpful for my problem.

I try to use the PdfViewer in an addin (using the .net managed addin framework), hosted in a winform host application. When I open a pdf file I get this exception:

   at Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.Utils.Helper.get_Dispatcher() in c:\TB\105\WPF_Scrum\Release_WPF\Sources\Development\Documents\Fixed\Core\FormatProviders\Pdf\Utils\Helper.cs:line 25

   at System.Threading.ThreadHelper.ThreadStart()

I suspect the helper class is using Application.Current.Dispatcher. Application.Current is null in our environment.

Is there a work around for this problem so I can use the viewer in an addin?

Thank you,

Fonger.

Hi.
I have a problem setting minimum or maximum values for a RadSlider I need to generate by c# code inside a propertygrid with the help of FrameworkElementFactory.

Value binding and setting the grid column work perfectly but I am not able to set min or max slider value (and tickfrequency, too - are they readonly?).

What do I do wrong here? Or is there a better way to add properties like a radslider control inside a radpropertygrid on the fly?

Here is a code snipet:

hi

I created a wpf App with a Dockpanel and Gridview controller, i referenced the DLL's with noXaml and included the Xaml from the Themes.Implicit, in App.Xaml.css  i have created a static constructor with this signature.The CustomLocalizationManager is a subclass of
LocalizationManager and use a resource.resx for the switch key for the language. The problem is when i debug the code i notice in the InteliTrace the exceptions




 

What am i doing wrong or is that normal.
thanks regards

We are using your trial version .Now we face some problems for radrichtextbox
1. We save document by following code
   public void ExportContent(string defaultExtension, string filter,IDocumentFormatProvider formatProvider)
        {
            var saveFileDialog = new SaveFileDialog
            {
                DefaultExt = defaultExtension,
                Filter = filter
            };        
            saveFileDialog.FileName = wordfilepath;
                using (var outputStream = saveFileDialog.OpenFile())
                {
                    formatProvider.Export(radRichTextBox1.Document, outputStream);
                }           
        }
2 . Now when we insert picture using teleriks insert picture method .Picture is inserted and file is saved by above method.Then on another form we cannot display this image on richtextbox .So I added code to picture command as follows
string fieldName = ((RadRibbonButton)e.Source).Text;

            if (fieldName.ToUpper() == "PICTURE")
            {
                MergeField mf = new MergeField();
                mf.PropertyPath = fieldName;
                IncludePictureField picField = new IncludePictureField();
                picField.SetPropertyValue(IncludePictureField.ImageUriProperty, mf);
                this.radRichTextBox1.InsertField(picField);
            }
            else
            {
                radRichTextBox1.InsertField(new MergeField() { PropertyPath = fieldName });
            }
this insert image and also label PICTURE as merged field but on form where this rtf file displayed in richtextbox it shows "Cannot display image"
3. Please tell us teleriks proper method to insert image and display on richtextbox (Field merge method).We are new teleriks method.
4. Also When we create Header and footer in Teleriks editor and save file in rtf. When this rtf file loaded again it doesn't shows header and footer .Please tell me reason behind this.

I looking for an event to handle before RadDataForm.CurrentItemChanged happens. 

At CurrentItemChanged, the CurrentItem is already the new item, but I need to carry out some operations on the old item. 
So I'm looking for something like "BeforeCurrentItemChanged" or "PreviewCurrentItemChanged" or "CurrentItemChanging" etc.

Hi,

I am trying to migrate a coded UI test to validate the contents of a RadGridView table which has replaced a WPF GridView control.  Previously the test retrieved the contents of the table something like;

 
 
With RadGridView I can access the column headers and find out the number of rows, however there are no rows held against the table in the Rows property.  If I try to add a validation against a single cell in the coded UI test builder they appear to be under a separate hierarchy (UIPART_GridViewVirtualCustom).  

I can't create individual validations against each cell using the coded UI test builder as the volume of cells to validate makes that unwieldy so I need to be able to validate them programatically which we were able to do with the standard WPF GridView control through the Rows property.

Can anyone provide any suggestions as how I can programatically check the RadGridView contents using codedUI.

Thanks in advance

Hello;

I am working on a project with the following requirements :
- I have a dashboard with a set of tile view items in different size (large, small, medium).
- Each tile item size has its content.
- In the normal (medium) view, I need to add a button "properties". When the user clicks on, a child window will be opened in order to set the properties of the tile view item and filter the information to be displayed in the different views.

I am stuck in the third part. As the tile view item is a user control, I found a solution on internet based on behavior which allows me to open the child window, however, i cannot implement the close & OK buttons using MVVM.

I need your support on this point.
Thanks for your help.

Best regards

Sam

In the attached screenshot, I have a  single 3D bar series.  I've set the labels at a 30 degree angle so they won'd overlap. However, they now overlap with the axis title. Is there a way for me to specify a margin for the title, or is there some other mechanism I can use to prevent this overlap?  Thanks - Mitch
