GridViewMaskedTextBoxColumn throwing validation errors for numeric input with MaskType="Numeric"

[Hasanain]

Hello,

I have the following column defined in my xaml code

<telerik:GridViewMaskedTextBoxColumn Mask="P1" MaskType="Numeric" 
DataMemberBinding="{Binding CurrentAllocationWeight}" 
DisplayIndex="1" IsReadOnly="True" DataFormatString="{}{0:P1}"  
Header="% Of Total" ColumnGroupName="CurrentAllocation"/> 

The bound property is a null-able decimal value. I have no other validation in the code-behind. When I try to enter a value in the cell, I get a validation error: "DecimalConverter cannot convert from System.Double".

How should I fix this, so that the user can enter say, 5.5, and it would display that value as "5.5%" in the cell?

Hello,

 If you want to bind the GridViewMaskedTextBoxColumn to Decimal or Int , you should use Converter for the Binding. In the ConvertBack method you should manually convert back from Double.

As to the DataFormatString you could define it like so: 

DataFormatString="{}{0:#%}"
