Hi, I'm trying to create a class deriving from the GridViewDataColumn. For example, I'd like to make the FontWeight Bold based on the bounded value. I was able to do it successfully for the view control by overriding CreateCellElement. So I thought overriding CreateCellEditElement would be the other method of the edit control but it is not working as expected. Attached is an illustration of the issue. Also, I have a sample project but I can't attach it here.

Thanks

gridview resorting after editing rows

Hi guys,

I've got a telerik rad grid view data bound to a CollectionViewSource with group descriptiors enabled. But it seems that when I edit a cell and then commit it, the row gets shifted to the bottom of the current grouping.

Is there any trick to stop this re-ordering?

[Solved] ContainerBindingCollection in WPF

I am trying to get a CountainerBindingCollection and ContainBinding to work with my hierarchical data template in wpf but no matter what namespace I use it doesn't seem to recognize it.

This link is to one of your WPF pages showing the ContainerBinding being used and it seems to be in the same namespace as the RadMenu , I have Access to the Menu but not the ContainerBindings, is this page of information wrong?

http://www.telerik.com/help/wpf/radmenu-how-to-enable-disable-menu-items.html

At the bottom of this page there is a link 'to learn more about container bindings' which leads to a page that never even mentions the containerbinding

Save and Open GanttView from external file

I tried searching in the demos and samples and didn't see any method to plug-in that would allow saving and opening of ganttview data from an external file, such as an xml. The only thing I found was by using MSProject importer/exporter but I want to be able to save and open on computers without that software. Is there something you can point me to or am I on my own to devise something? Thanks.

[Solved] How to add a Gap between Horizontal Bar Chart Series ?

In a Horizontal Bar Chart I want to add a small gap between the bar series. I have managed to do it in Vertical Bar Chart like this:

01.FrameworkElementFactory borderFramework = new FrameworkElementFactory(typeof(Border));

02. borderFramework.SetValue(Border.BackgroundProperty, brush);

03. borderFramework.SetValue(Border.OpacityProperty, 0.7D);

04.

05.// set a small space between the bar/columns just like chartjs does it

06. borderFramework.SetValue(Border.BorderThicknessProperty, new Thickness(2, 0, 2, 0));

07.

08.... new BarSeries(){

09....

10. PointTemplate = new DataTemplate()

11. {

12. VisualTree = borderFramework,

13. },

14.}

Exception using access text to go to the backstage

We recently (a few months ago) switched from Q3 2017 to R1 2019 SP1, and traced the origin of this exception to switching to the new version. I.e. it did not have this issue with the older version.

We are using implicit styles and it only happens in the 2013 theme, at least among the themes that we use.

If we press Alt, and then "F" to get to the backstage, we get the following exception. After the exception everything works normally, but you have to press Alt again to get the access text to show on the backstage.

Object reference not set to an instance of an object.
