Basically, improve the approach suggested in the following article to provide a more generic solution, applicable for multiple aggregate fields: http://www.telerik.com/help/aspnet-ajax/grid-aligning-items-in-group-header.html
Currently Linq2Sql expressions are supported. But as Entity Framework is "de facto" the standard for data access in .NET, it would be great, if you also support ESQL expressions. This is necessary for example when data binding to entities in OnNeedDataSource event and filter expressions from RadGrid should be used for adapting query. Thanks, Roger
Currently it's not possible to overrule number of pages to be shown in page navigation, if EntityDataSource is used. There is the problem that always all rows from data source get queried, when GridGroupByExpression has been defined for RadGrid - and this is really a problem, if data source has hundreds of thousands of records (as in our case). The performance is really bad. To overcome this issue I would like to control myself, which data gets returned by adapting query in OnQueryCreated event of EntityDataSource, basically by "injecting" skip / take expression to entity query. I am responsible myself about sorting and grouping should be done on page level only (so there is no need to query always ALL data). In same event I want to set VirtualItemCount, which should control number of pages to be shown in page navigation (in combination with AllowCustomPaging). But unfortunately this setting is not taken into account by RadGrid for displaying pages in page navigation. Is it possible to overrule this behavior that VirtualitemCount is always taken into account when AllowCustomPaging has been enabled? I would like to control myself. Thanks, Roger
Hello, I would like to have the group footer display the total items count in that particular group but the way the radgrid is designed it almost seems impossible and it is requirement for us. I would also appreciate if you would consider adding the aggregate for the entire group in the group footer and the entire grid in the grid footer. Thanks Chaitanya Vemulapalli
The problem is a limitation in the current implementation. It is due to the fact that when drag and drop are enabled the grid selects the item(mousedown) using the built-in selection logic. Later when click is fired the row is again selected. The selection logic is designed in such way that if you try to select an item which is already selected it will first deselect it and later select it. It is rather complex and handles various scenarios, altering it will result in a breaking change which is not desirable.
I want to use tab key for filter. First i am entering filter text in first column then pressing tab. So i want after press tab the courser should go to next column and should allow typing. Check my demo first search with name column then press tab key the courser not going to next column and not allowing typing.
Currently, RadGrid with Frozen Columns can be scrolled horizontally by touching the data records, which breaks the Frozen Columns functionality on mobile devices as all columns get scrolled. And the only way to keep the first columns frozen under touch devices is to use the horizontal scrollbar below the RadGrid for scrolling.
As a user I would like to see on each grid the aggregate function totals for the actively displayed grid and on the last page the aggregate function totals for the active displayed grid and the data set aggregate function totals so that each page displays only its page level total and on the last page displays the full total of all data displayed. See attached examples: Example: Page level Total on every page and on the last page Page level Total plus Grid whole Total on the last page.
