When you place a DataTrigger whithin a CellTemplate, it is being ignored by RadGridView for WPF

Workaround ( until fixed ) - set the ContentTemplate of the cell via Style in a static resource instead.

Columns with * width are not measured correctly when GridView is placed in ScrollViewer and its width is changed.

GridView ColumnGroup Header does not refresh when bound to view model

1. Define a custom AggregateFunction for a column
2. Group on a column
3. A calculation on the AggregateFunction is invoked
3. The Grouping.Key (of the input parameter) corresponds to the correct key
4. Edit a value on the column (having the AggregateFunction)
5. A calculation is invoked, but the Grouping.Key is "1" and not the correct key.

1. Set RadGridView's setting DragElementAction="ExtendedSelect". 
2. Open a window on selecting a row.
3. Close the window, the RadGridView becomes ExtendedSelect.

Note: Most probably this problem is actually caused by a limitation in the Silverlight platform. Once a Window is shown, there is no way to detect that the mouse is released.

The sort index will not be displayed when applying a custom sorting without adding a SortDescriptor, You can consider implementing Custom Sorting using the IComparable interface instead. As an example please refer to the Custom Sorting with IComparable WPF Demo. Using a generic SortDescriptor would also be an option.

Hi Telerik-Team,

When creating a new item in the GridView by either mouse or insert button the row is not selected or highlighted.

I guess this is a bug, since a cell in the new row has focus but not the row.

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

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.

gridviewdatacolumn distinct filter does not respect culture when displaying dates.

All the other display do display the correct format

The performance of the RadGridView scrolling diminishes significantly when the grid has thousands of rows and alternating row styles are used.  This causes scrolling to be virtually unusable.  I note this is a known limitation of the RadGridView from information from https://docs.telerik.com/devtools/wpf/controls/radgridview/troubleshooting/performance 

We have had to remove the alternating row styles from our current product while porting to the RadGridView.  I am requesting if this issue is going to be fixed in the future anytime soon.

1. Select the first row.
2. Hit Ctrl-End to jump to the end of the list. 
3. Hold down the Shift key and select the last row. 
4. Scroll up and notice that everything between the first page and the last page is not selected.

* there is a sample project attached in the support thread

Using Telerik GridView. If a cell is wrapped multi-lines (the more lines the easier to reproduce), and the grid has both vertical and horizontal scrollbars. 
1) Fill one of the cells with a bunch of text in which will cause multi-line text wrapping of within that column.
2) Set focus to a different grid row
3) scroll the vertical scrollbar all the way to the bottom
4) scroll the horizontal scrollbar far enough away to lose visual of the Column
5) scroll the horizontal bar back to the right
Result: the vertical scrollbar will jump.
Expected: The scrollbars should not jump like this as it does not happen when the cell does not contain word-wrapped text.
