When using INotifyDataErrorInfo, items are still validated even when the ValidationType property is None.

 

Please note that when the AutoGeneratedColumns property is set to true, the item's HasErrors property will be evaluated, but only once.

 

 

Provide a way to change the ItemsSource of the control while it is exporting using SpreadStreamExport.RunExportAsync() method

When SpreadStreamExport.RunExportAsync() method is exporting large data it could take a while to export the grid. While exporting the grid, the ItemsSource changes to a new one with a different number of columns, NullReferenceException is thrown.

The MatchAllTerms search mode doesn't behave as epxected when the GroupRenderMode property of RadGridView is set to Flat.

To work this around, set the GroupRenderMode property of RadGridView to True.

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 GroupRenderMode of the RadGridVIew is set to Flat. The control is populated with items that implement the IList interface. The Count property of the custom objects needs to return value bigger than 1. So when the Delete button is pressed, the rows beneath the deleted one will also be deleted. Their number depends on the Count property of the custom object.

 

When using Entity Framework Core 3 an InvalidOperationException is received upon adding an AggregateFunction to a column. 

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. 

DataContext of rows is sometimes null when UI virtualization is enabled in the Flat group render mode.

The issue appears also without UI virtualization and in the Nested mode. It happens on ItemsSource reset of RadGridView, in case the old ItemsSource value wasn't empty. The DataContext is set to null for a brief moment before the old visuals are removed from the view, which causes issues in some scenarios related to CellTemplate

The RowValidating event arguments give information about the edit operation that triggered the row validation - None, Edit or Insert. However, when the edit is canceled the EditOperationType is set to Edit. Change this and provide a new value (Cancel) or use None when the validation is canceled.

As a Followup to this (Bad performance with grouping)Forumpost I managed to reproduce the issue now.
Since i cannot upload zip-files in the Forum I am doing it here.


The problem is, that a single grouping dramatically increases the time for sorting the values.
When the grouping is not present, sorting the same column is much faster.


It appears that it is related to the ammount of columns in total (not grouped).
The ammount of records is not so important, 100 (as in the attached sample) should not be significant.

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.

Expose a way to use Search As Type functionality with Accent Insensitive.

When adding a new row and we click inside a DropDownContent of a DropDown control, the RadGridView loses focus. This way RowValidating event is called which is not expected.

Wrong selection when data is real time updated

Numeric cells are exported in string format.

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.
