![]() dataGridView1.DataSource myobjectNewList var grouper new (dataGridView1) grouper.SetGroupOn ( ' aProperyNameOfMyObject' ) // or grouper.SetGroupOn (dataGridView1. Has anyone encountered this issue and has solutions to speed up the performance. If the list is a new one, it seems that the right way is to reapply the code snippet: Shrink Copy Code. I have contacted DevExpress support and they told me that I have to calculate summaries myself and then paint them but isn't the whole point of their feature for them to do this? I used performance profiler dotTrace 2016.1.2 and it looks like DevExpress XtraGrid fires off DoTypedSum when OnListChanged is fired and recalculates summaries for each group row each time BindingList is updated. When I have 1500 items the XtraGrid blocks UI thread and whole application locks up. ![]() When I have 300 items and grid is grouped by one column with market data turned on the lag is minimal and group summary recalculates without a problem. ![]() There is a market data feed that updates BindingList quite frequently (every 5 sec) and then BindingList fires of OnListChnaged. When I create a GridColumn that needs to show a summary I subsequently create GridSummaryItem for that column. I have customized BindingList for XtraGrid datasource where T is just POCO objects. What I wanted to do is to group by any column and then some of the numeric columns will show totals in the group row. The control gives you the choice of 3 data layouts single record (similar to the Properties window of the MS Visual Studio), bands layout (one record is. They all support things like grouping headers and drill downs. A universal app running on a mobile phone may start behaving the way it would if it were running on a tablet when the mobile phone is connected to a desktop computer or a suitable docking station.Using DevExpress XtraGrid 16.2 for grouping and aggregation. I think you will be best served with a third party grid control, like DevExpress XtraGrid or Janus GridEx, at least until Microsoft decides to provide us with a useful (for anyone doing anything more than very basic data processing) grid control. A universal app may run on either a mobile phone or a tablet and provide suitable experiences between the two. These extensions allow the app to automatically utilize the capabilities that are available to the particular device it is currently running on.

Universal Windows apps that are created using the UWP no longer indicate having been written for a specific OS in their manifest build instead, they target one or more device families, such as a PC, smartphone, tablet, or Xbox One, using Universal Windows Platform Bridges. In the leaked build, users can go back to the old Start Menu with live tiles by creating a new DWord value using Registry Editor: Open Regedit (Registry Editor. The UWP is an extension of the Windows Runtime. Designed as an extension to the Windows Runtime platform first introduced in Windows Server 2012 and Windows 8, the UWP allows developers to create applications that will potentially run on multiple types of devices. ![]() The API is implemented in C++, and supported in C++, VB.NET, C#, and JavaScript. If several columns are involved in grouping, the current column will reside at the bottom grouping level. Calling this method has no effect if data is already grouped by the values of this column. To group data by the values of a given column, call its Group method. It supports Windows application development using C++, C#, VB.NET, or XAML. Grid Views support grouping data by an unlimited number of columns. The purpose of this software platform is to help develop Metro-style apps that run on both Windows 10 and Windows 10 Mobile without the need to be re-written for each. What is UWP? UWP stands for Universal Windows Platform which is a platform-homogeneous application architecture created by Microsoft and first introduced in Windows 10.
