Users reported that the Text Search feature is misbehaving for certain columns in their grid.

We found that that if we take the Telerik example “DeferredSearching_WPF.sln", and change the "int" field+property to "long" , text search for a number indeed falls over.

Can you reproduce this?

Kind regards, Bertus Distributie ICT

Expose a collection which holds the region of the currently selected cells.

When the RadGridView is bound to a collection of DynamicObject and runtime we add a new property to the objects, this new property will not be respected. The columns will not be refresh.

Our requirement is to navigate through RadGridView table header using keyboard tab navigation.

The header may or may not include checkbox/filter button.

However on mouse focus on table headers , it get highlighted. This feature is currently not possible with tab navigation.

Numeric cells are exported in string format.

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.

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

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.

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.

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

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

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.

 

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.

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.

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

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.

 

 

When GridView is bound to items (ICustomTypeDescriptor) which contain a property with a dot in the name, the values in the column are not shown
