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

Currently, the GridViewMergedCell cannot be selected. Allow selecting the merged cells via the UI or code. 

At the moment RadGridView has only a CurrentMergedCell property.

In the following scenario:

<telerik:RadGridView x:Name="clubsGrid" ItemsSource="{Binding Foos}" AutoGenerateColumns="False">
	<telerik:RadGridView.Columns>
		<telerik:GridViewDataColumn DataMemberBinding="{Binding Foo1}" MinWidth="100" />
		<telerik:GridViewDataColumn DataMemberBinding="{Binding Foo2}" MinWidth="100" />
		<telerik:GridViewDataColumn DataMemberBinding="{Binding Foo3}" Width="*" />
		<telerik:GridViewDataColumn DataMemberBinding="{Binding Foo4}" MinWidth="100" />
		<telerik:GridViewDataColumn DataMemberBinding="{Binding Foo5}" MinWidth="100" />
		<telerik:GridViewDataColumn DataMemberBinding="{Binding Foo6}" MinWidth="100" />
	</telerik:RadGridView.Columns>
</telerik:RadGridView>

<DataGrid ItemsSource="{Binding Foos}" AutoGenerateColumns="False" Grid.Row="1">
	<DataGrid.Columns>
		<DataGridTextColumn Binding="{Binding Foo1}" MinWidth="100" />
		<DataGridTextColumn Binding="{Binding Foo2}" MinWidth="100" />
		<DataGridTextColumn Binding="{Binding Foo3}" Width="*" />
		<DataGridTextColumn Binding="{Binding Foo4}" MinWidth="100" />
		<DataGridTextColumn Binding="{Binding Foo5}" MinWidth="100" />
		<DataGridTextColumn Binding="{Binding Foo6}" MinWidth="100" />
	</DataGrid.Columns>
</DataGrid>

in the native DataGrid after the Width of Foo4 column is increased towards Foo3, then the Width of Foo5/Foo6 columns can also be increased. We can implement similar behavior in the RadGridView as well. 

I want to get ItemsSource by retrieving a list from a dictionary, so I need 2 parameters, but I can't use MultiBinding to do this!

You can find our online documentation on a detailed information on the currently supported grouping:
http://docs.telerik.com/devtools/wpf/controls/radgridview/grouping/basics.html

When dealing with Date column filters show available options (similar to text filters) and support grouping based on Year, Month. This is a very handy feature of Excel.

The functionality is documented at http://docs.telerik.com/devtools/wpf/controls/radgridview/filtering/icolumn-filter-descriptors and for the time being the functionality can be achieved by implementing an attached behavior. 

Hello,

Regarding this forum question, it will be good if you add the attached property VisibleColumnsCount or IsAnyColumnVisible so I can hide the rows when there are 0 columns. Please read the following link for full information:
