When the ItemsSource of the RadGridView is set to an implementation of ICollectionView, the Groups property is not utilized, since the groups are generated internally by the RadGridView. We can consider introducing support the Groups property to allow for grouping customizations.

Hello

I have often faced a scenarion where I have groups (GroupDescriptor), but those groups need to be ordered by a different property.

Usually, telerik column properties already provide a SortMemberPath.

<telerik:GridViewDataColumn DataMemberBinding="{Binding Name}" SortMemberPath="Id"


However, the GroupDescriptor does not have that, it only has Member and SortDirection.

The only way to set the sort to refer another property is in code behind using a generic group descriptor. It is very flexible, but it has several drawbacks, since now I'd have to declare everything in C# (aggregate functions, templates, etc) and also lose the Design time feedback from Visual Studio.

My request is to just have the possibility to set a SortMember in XAML which will work for most scenarios, same way as others components already do.

<telerik:GroupDescriptor Member="OrderState" SortDirection="Ascending"
                                         SortMember="OrderStateIndex" >

 

Thanks

Currently, the ControlPanelItem expose only standard CLR properties. Make them DependencyProperties so they can be data bound.

I am using a RadGridView to display appointments. I am adding paging to the control with RadDataPager. I am setting the ItemSource property for the RadGridView to {Binding Path=PagedSource, ElementName=unscheduledWorkOrdersRadDataPager }. I am then overriding the ConvertDraggedData(object data) method and using the DataObjectHelper class in order to obtain data from the object data parameter and then setting the returned IEnumerable<IOccurence> accordingly.

The problem is that whenever I added paging to the RadGridView. The DataObjectHelper is not able to properly retrieve the dragged data from the object data parameter.

We can consider introducing functionality that allows users to conditionally style/format the control in a similar manner as the WinForms feature: https://docs.telerik.com/devtools/winforms/controls/gridview/cells/conditional-formatting-cells.

When exporting there are several ways of telling the exporting class which column to exclude during export (through options or by cancelling the export of the column in an event). It would be easier if there was an "IsExportable" property on GridViewDataColumn so that the export can take that into account. No options or events would then be necessary when exporting.

Using SearchPanel and getting search results highlighted is a very usefull feature. However at the moment it is only possible to change the color of the highlight-portion of HighlightTextBlock. It would be nice if I have more formatting options like:

  • HighlightFontWeight
  • HighlightFontStyle

etc. So if I search for "find" I get results like "find me"

Currently, when you scroll the RadGridView control the "click here to add new row" button goes out of the viewport. Allow to pin the button, so it float at the top or bottom of the viewport and to be always visible.
