I've had a standard ComboBox working with this code:

I switched over to the RadComboBox, thinking I could do almost exactly the same thing. However when I select the drop down, I get no items. If I remove the ContainerStyle then that works a treat.

I've looked at the various examples in the help, but nothing seems to work.

Both these code examples fail:

I amended one of the Telerik ComboBox examples to demonstrate as that does exactly the same thing. Can't attach, so it's available here: ComboBoxCustomFilteringDemo.zip

I'm really stumped as to what I've missed, as this should really be such a simple thing to do.

BTW I'm running the latest 2015.1.225 WPF version

We have an application in which we would like to support a custom clipboard format for copying\pasting in a RadRichTextBox. I have read your article on clipboard support (http://docs.telerik.com/devtools/wpf/controls/radrichtextbox/features/clipboard-support), but that seems to mainly deal with changing which provided clipboard formats are used.

It appears that if I register a custom format provider with ClipboardEx, that would be able to handle pasting the custom format. For example:

However, I don't see a way to handle copying a custom format without intercepting the CopyExecutingCommand and adding the custom format the the clipboard. For example:

However, I would want to make sure that the default clipboard formats are still added to the clipboard in addition to our custom format.

Can you provide any guidance on the best way to handle copying and pasting a custom clipboard format?

Thank you.

In addition to the class provided by the class, I ask if there are any classes or methods that can be applied to a class that has style gridview

ex) no applied style gridview export option source, I want to applied style gridview export option

 public bool SaveDocument_GridViewUse(RadGridView gridViewList, ExcelExportTypeFDC selectedFormat)
        {
            try
            {
                string fileName;
                string appFileName = "";
                using (Stream stream = CreateFile(out fileName, selectedFormat))
                {
                        gridViewList.Export(stream, new GridViewExportOptions() {
                        Format = ExportFormat.Csv,
                        ShowColumnHeaders = true,
                    });
                }

                if (selectedFormat == ExcelExportTypeFDC.Xlsx) appFileName = "excel.exe";
                else if (selectedFormat == ExcelExportTypeFDC.Csv) appFileName = "excel.exe";
                else if (selectedFormat == ExcelExportTypeFDC.Txt) appFileName = "notepad.exe";

                ProcessStartInfo pInfo = new ProcessStartInfo(appFileName, fileName);
                pInfo.WindowStyle = ProcessWindowStyle.Maximized;
                Process.Start(pInfo);
            }

The following is the code snippet from my code.  I have the command CheckTypeCommand defined in my Model. There are over 100,000 items in my collection and the number of columns is 50 odd. If I scroll up or down of this grid the command of this check box for every row that is render is getting executed. I want the command only to execute on UI trigger that is when I change the Check Type in the combobox. Can you please let me know what is I am missing here. If I disable Virtualization then the performance goes for a spin.

Hi!
It is seems that gridview doesn't separate null value and enum's first value while filtering or sorting.

Example:

Hello everyone,

is it possible to disable the search criteria modifiers like +,- and " so that those characters are treated like any other? We have a grid that contains some records that start with a minus (e.g. -test, -1234), however when users start typing "-123" no results are returned. 

In the ViewModel the property looks like this:

Now on my detail.xaml the stuff for my RadDiagram is loaded from an external xaml, let's call it "raddiagram.xaml"

Finally I'min the raddiagram.xaml :-)

With this example xaml - taken from the documentation --> two-way-mvvm , my shapes are shown (still the content needs a toString, but this is not the big problem here).
Unfortunately all shapes are laying at position (0,0) - but when trying to achieve anything written in with styles / templates nothing is shown anymore.

Question: How can I achieve, via a property access of a ViewModel, that I can "iterate" in my xaml over all shapes to style them (setter property position etc.).
The goal is (later) after the three shapes are shown correctly (as you can see above, the x-position is the same, but y- is increasing) to insert connections between them.

I tried this: http://docs.telerik.com/devtools/wpf/controls/raddiagram/howto/mvvm-style-selectors but then nothing (shapes) is shown anymore on the RadDiagram.

Thanks for any hints/help

Hello, 

I have been trying to figure out how I can set the Label on a Categorical Axis to pull from my data object.  After hours of searching I was not able to find any examples or answers to this.

I have a set of objects which I am binding to for the series and plot points.  

In the XAML, the PlotCategory binds the category values on the chart, whereas the PlotValue binds the values on the chart.

Here is the XAML in which I am binding (note: I did not include all of the various resources since those already work)

However, instead of the PlotCategory being used for the labels, I want the CategoryAxisLabel to be used instead.  The reasoning I need to do this is that in my data I have multiple events which happen on the same date.  When I originally plotted the chart all of the data points were plotted on the same day.  For a line chart that looked horrible.  So to change this I now plot to the events which gives me the lines desired, but now I want to display the date for the label and not the event number.  I have not been able to find a way to do this, and it is the last hurdle I need to overcome.

Thank you
