The DataType property of GridViewComboBoxColumn does not work as expected in the following scenario:

1. Set DataSource to GridViewComboBoxColumn so that the ValueMember of the column is of type Integer.
2. Set the DataType property of the column to Decimal.
3. Set DataSource of RadGridView so that the FieldName of the above GridViewComboBoxColumn is of type Decimal.
4. RadGridView throws exception.
