Release LIB 2022.2.627 (27 June 2022)

Some of the rows of the RadGridView control are missing, when placed inside a RadPane and one of the newer themes is set via StyleManager.

As a workaround, set the UseLayoutRounding property of the RadGridView control to False.

The property changed of the property bound to IsExpandableBinding (property of RadGridView) is not reflected in the row. To reproduce this the IsPropertyChangedAggregationEnabled property of RadGridView should be set to True (which is the default value) and the view model property (bound to IsExpandableBinding) should be updated consequently with other properties of the view model. For example:

myRowModel.Name = "New name";
myRowModel.IsExpandable = false;

To work this around, use the IsExpandable property of GridViewRow. You can data bind it using the RowStyle property of RadGridView. Or alternatively, set the IsPropertyChangedAggregationEnabled property of RadGridView to False.

Currently, the elements in the row details are measured with infinity size. This means that if you want to limit the content within the available space of the row, you will need to set the Width of the content manually. Add a mechanism that allows you to alter this behavior and measure the child content with the available space.

Column widths are not calculated correctly when star-width columns are added dynamically which leads to the appearance of a horizontal scrollbar when it is not required.

If you add a column with IsReorderable set to False and then drop another column over it, nothing should happen. However, sometimes the drop is executed and the not reorderable column is moved to another index.

To work this around, cancel the reordering in the ColumnReordering event if the drop target column cannot be reordered.

private void RadGridView_ColumnReordering(object sender, Telerik.Windows.Controls.ColumnReorderingEventArgs e)
{
	int notResizeableColumnIndex = 1;
	if (e.NewDisplayIndex == notResizeableColumnIndex)
	{
		e.Cancel = true;
	}
}

Release LIB 2022.2.606 (6 Jun 2022)

Currently, to modify the background color of this element, the default control template of the GridViewCell element needs to be extracted, and the VisualState with x:Name="Highlighted" would need to be customized.

We could include an API for modifying the background color of the HighlightTextBlock element, when it is highlighted.

Hi

I have a grid where some rows contain child rows.  In order to control which rows have the "+" expander icon I use the IsExpandableBinding property.  I also have a toolbar which contains a convenience button to collapse all the expanded rows.

This button is bound to a handler which called RasGridView.CollapseAllHierarchyItems(), but this does not have any effect.  I've tried removing the IsExpandableBinding property, and the collapse mechanism then works (but I get unwanted expanders on every row).

Currently, the range of the ScaleFactor property is between 0.1 and 4.0. We could include API to allow the user to set minimum and maximum boundaries that are between the default range (0.1 and 4.0).

For example:

  • MinimumScaleFactor=0.8 
  • MaximumScaleFactor = 1.5

ArgumentOutOfRangeException with the following message is thrown: 'DataGrid_DisplayIndexOutOfRange
Parameter name: displayIndex'

The error appears when the SelectionUnit is Mixed and when you select a row, and then filter the data so that the selected row is in the filtered results. 

To work this around, clear the selection before applying the filters and restore it after this.

Release LIB 2022.2.523 (23 May 2022)

The issue appears when you have two adjacent columns - one resizable on the left and one not-resizable (IsResizing=False) on the right. If you hide the left column (IsVisible=False), the resize handle of the right column is still there and it can be used to resize it. 

To work this around, you can remove the next column and add it again in the Columns collection, after you hide the previous column.

this.gridView.Columns[1].IsVisible ^= true;            
var nextColumn = this.gridView.Columns[2];
this.gridView.Columns.Remove(nextColumn);
this.gridView.Columns.Add(nextColumn);

The SelectedCells collection of RadGridView contains wrong cells in a scenario where the previous selection is cleared and then its items are filtered out of the view. This reproduces with SelectionMode set to Extended and SelectionUnit set to Mixed.

This happens if you call gridView.SelectedItems.Clear() or gridView.UnselectAll(). You can work around the issue if you clear the SelectedCells. To do so, call also gridView.SelectedCells.Clear().
gridView.SelectedCells.Clear();

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
