Also, When I run your Hierarchical data sample in the "Explore WPF Elements", and I apply the Alloy theme, the foreground color is black.... that makes it unreadable against the dark background. |

Hello The DataGrid performs great with real time updates. Though using hierarchical data isn't quite as fast as non-hierarchical data. The hierarchical structure does use virtualization though, that is, it only considers the nested collections when they are opened. Have a play around with loading the data grid with however much hierarchical data you need and see what the performance is like. Sorting hierarchical data does only sort the parents and not the children. At the moment this is fixed but this is on our backlog. At the moment our data grid does not have a built-in filtering engine. Again this is on our backlog. The bulk of the memory leak is resolved. Yes, all our controls are customizable with WPF templates and styles. All the xaml code for our themes come with the WPF Elements control suite which you can follow. Some of the controls are quite large, so if you need any help with styling anything, let us know and we'll point you in the right direction. Yes the DataGrid supports an ObservableCollection as the items source and you can show hierarchical data. The foreground of the Alloy style is actually white. WPF has a problem with dynamically changing the foreground of elements when the theme dynamically changes. Try this: In the sample explorer, go to a DataGrid page, and change the theme to Alloy. Now use the arrow buttons at the bottom of the Sample Explorer to slide to the next demo. Now you will see the foreground is white. If you change to OfficeBlue, you will see the same issue but in reverse. In you application, if you want to use the Alloy theme, this foreground issue isn't going to be a problem. Jason Fauchelle |

Thank you Jason, I tested the performance of your grid with real time data, and so far my tests show you on top of Telerik, Syncfusion, and DevExpress. Congratulations. It looks very promising. I'll be ready to spend some more time testing it as soon as you are able to add sorting and filtering to hierarchical data. Best, Nestor |

What is the difference between Multicolumn tree view and the Hierarchical data in your data grid? Is it possible to change the icon for each node? |
|

Hello Nestor The main difference between the MulticolumnTreeView and the Hierarchical DataGrid support is that the DataGrid can handle more data with better performance. Neither of them have an option to set a node icon, but they both support templating which would allow you to include icons. Jason Fauchelle |
