ShowColumnSortIndexes default value

[KJ]

Hi,

I'm trying to set a default value for RadGridView's property ShowColumnSortIndexes. I've tried to do so by adding a style to App.xaml:

<Style TargetType="telerik:RadGridView"><Setter Property="ShowColumnSortIndexes" Value="True" /></Style>

The project builds, but when the first gridview is displayed I get the following error in visual studio (2012):
The property "ShowColumnSortIndexes" is not a DependencyProperty. To be used in markup, non-attached properties must be exposed on the target type with an accessible instance property "ShowColumnSortIndexes". For attached properties, the declaring type must provide static "GetShowColumnSortIndexes"  and "SetShowColumnSortIndexes" methods. 

When settings the property directly on an individual RadGridView, it works as expected.

Can you please show me how to set an application wide default value for this property? I'm using 2014.2

Thanks,

KJ

Hi KJ,


Thank you for contacting us. 

ShowColumnSortIndexes is not a dependency property, indeed.
By that reason you could not define simple style targeted at RadGridView and set its value to True.  

If we introduce such property, it would definitely lead to a breaking change, that we want to avoid.  

As it turns out, with the current version of RadGridView I could not recommend you any appropriate workaround. 

For the time being you may set this property to True only to specific instance of RadGridView.

Hi KJ,

a solution to the problem would to define your own grid view class that descends from RadGridView and sets this property in the constructor. Then use this class instead of the Telerik one.

Don't forget to define the default style for your control at the application level; otherwise, the grid view will not be displayed.
