Hi,

When a try to assign a System.String to the FilterMemberType property of a GridViewComboBoxColumn, at runtime it throws the following exception: Failed to create a 'System.Type' from the text 'System.String'

What am I doing wrong?


Thanks in advance,

Nuno

Hi Nuno,

 May I ask you to share how exactly do you assign the FilterMemberType?

Hi Didie,

I just realized I didn't tell that the assignment was in Xaml. Here's how I'm doing it:

<telerik:GridViewComboBoxColumn Width="Auto"
                                                        ItemsSourceBinding="{Binding PosicoesPautais, Source={StaticResource RelatedTablesKey} }"
                                                        DisplayMemberPath="Codigo"
                                                        SelectedValueMemberPath="ID"
                                                        IsComboBoxEditable="True"
                                                        IsSortable="True"
                                                        IsFilterable="True"
                                                        FilterMemberPath="Codigo"
                                                        FilterMemberType="System.String"
                                                        DataMemberBinding="{Binding PosicaoPautalID, Mode=TwoWay}"
                                                        Header="Posição Pautal">
                            <telerik:GridViewComboBoxColumn.EditorStyle>
                                <Style TargetType="telerik:RadComboBox">
                                    <Setter Property="IsReadOnly"
                                            Value="True" />
                                </Style>
                            </telerik:GridViewComboBoxColumn.EditorStyle>
                        </telerik:GridViewComboBoxColumn>


Thanks,
Nuno

Hi,

 You should specify a Type, not s String. Please check the general forums to learn how to set a system type in Xaml.
