QueryableEntityCoreCollectionView internal collections not in sync.
Currently, there is no workaround to this behavior.
While clicking in the GridViewRows, some items might appear selected although they are not foreign group and SelectionChanged is not fired for them being as added items.
Currently, if RadGridView is bound to a INotifyCollectionChanged collection and the collection class raises the CollectionChanged event with NotifyCollectionChangedAction set to Add, Remove or Insert, RadGridView is not updating its items properly when the OldItems or NewItems collections contain more than 1 items.
Add support for this scenario.
Dear Telerik Support Team,
I am encountering an issue with the RadGridView control in my application, which is impacting the usability for users relying on screen readers. Below, I have outlined the details of my development environment, the problem, and attached a sample project demonstrating the issue.
Issue Description:
In the attached sample project, I have implemented a simple RadGridView without any custom styling and populated it with sample data. I have observed that the focus behavior is inconsistent, particularly with the first cell in the RadGridView. When attempting to focus the first cell, only the cell itself receives focus, unlike subsequent cells where both the cell and the entire row are focused. This inconsistency results in screen readers failing to read out the content of the first cell, while they correctly read the contents of all other cells.
Upon further investigation using the Snoop utility to explore the visual tree, I noticed that the GotFocused event for the initially focused cell identifies it as being of type RadGridView, whereas, for other cells, the type is GridViewCell. This discrepancy seems to be at the root of the issue.
Attachments:
I have included a simplified, runnable standalone application that reproduces this behavior. Please find the sample project attached to this ticket.
I believe this might be a bug affecting the accessibility of the application, and I would greatly appreciate your guidance on whether this is a known issue with a workaround or if there's a fix available.
Thank you for your assistance.
Best regards,
Christian

StackOverflowException is thrown when perfoming sorting, filtering or grouping on GridView bound to DynamicObject
The header row (the group headers in a GridView, or a parent row in a TreeListView) stays in the screen while scrolling until all the children rows have been scrolled. The feature is available in R3 2017 Release of UI for WPF. Check what's new in R3 2017 here: http://www.telerik.com/support/whats-new/wpf/release-history/ui-for-wpf-r3-2017
ViewRow's background is not correctly colored when RadGridView is within RadBusyIndicator and it is busy. There is no problem if your are using GridViewLoadingIndicator.
The last row is not fully visible when the gridview is scrolled to the bottom in case RowHeight is set to less than 20px. The less the row height the smaller the part of the last row which is visible. This is reproducible only in Office2013 theme.
1) I created a 5 X 5 table. 2) Then I selected second column. 3) Then I applied Right Align to the selected column. 4)Then I Right clicked on the last row and selected Insert > Insert row below 5) It inserted the row with all cells left aligned. The cells should adapt the alignment of the column they are in.
Exporting to Excel for hierarchical grid view i.e parent and child grid. The Output Excel should be looks like drill down report which child report can be hidden/visible.
Wrong selection when data is real time updated
Pasted rows are not correct after coping all rows with SelectionMode Extended. This is caused by the incorrect count of the cells in SelectedCells collection. Resolved with LIB version 2014.1.0428.
When a gridview is placed in TabControl, the following CodedUI tests will fail: Test 1. Click on a column header to sort by that column. Test 2. Click on a drop-down button to filter a column. Test 3. Drag a column to group by it.
