GridViewMultiColumnComboBoxColumn search not working when name starts with a special character

[Quentin]

Hi,

I am using a GridViewMultiColumnComboBoxColumn in my GridView defined with the following code:

<telerik:RadGridView Grid.Row="1"
                                 AutoGenerateColumns="False"
                                 CanUserDeleteRows="False"
                                 CanUserInsertRows="False"
                                 CanUserGroupColumns="False"
                                 CanUserReorderColumns="False"
                                 CanUserSortColumns="False"
                                 IsFilteringAllowed="False"
                                 ShowGroupPanel="False"
                                 RowIndicatorVisibility="Collapsed"
                                 GroupRenderMode="Flat"
                                 ItemsSource="{Binding Materials}"
                                 AutoExpandGroups="True">
                <telerik:RadGridView.GroupDescriptors>
                    <telerik:GroupDescriptor Member="Category" />
                </telerik:RadGridView.GroupDescriptors>
                <telerik:RadGridView.Columns>
                    <telerik:GridViewDataColumn DataMemberBinding="{Binding Label}"
                                                Header="Name"
                                                HeaderTextAlignment="Center"
                                                TextAlignment="Center"
                                                IsReadOnly="True"
                                                CellStyleSelector="{StaticResource ReadOnlyStyle}"
                                                Width="Auto" />
                    <telerik:GridViewMultiColumnComboBoxColumn DataMemberBinding="{Binding RefSize}"
                                                               DisplayMemberPath="Size"
                                                               Header="Size"
                                                               HeaderTextAlignment="Center"
                                                               ItemsSource="{Binding PossibleSizes}"
                                                               TextAlignment="Right"
                                                               CellStyleSelector="{StaticResource ReadOnlyStyle}"
                                                               Width="250"
                                                               AutoGenerateColumns="False"
                                                               CloseDropDownAfterSelectionInput="True"
                                                               SelectionMode="Single"
                                                               SelectionBoxesVisibility="Hidden"
                                                               CanUserSearchInHiddenColumns="False"
                                                               DropDownHeight="350"
                                                               AutoCompleteMode="Search">
                        <telerik:GridViewMultiColumnComboBoxColumn.Columns>
                            <telerik:GridViewDataColumn DataMemberBinding="{Binding Material}" ShowFieldFilters="False" />
                            <telerik:GridViewDataColumn DataMemberBinding="{Binding Size}" ShowFieldFilters="False" />
                        </telerik:GridViewMultiColumnComboBoxColumn.Columns>
                    </telerik:GridViewMultiColumnComboBoxColumn>
                </telerik:RadGridView.Columns>
            </telerik:RadGridView>

Everything seems to be working fine except when I try to search for a value whose name starts with the '-' character (for example '-2Ni50'). Can you tell me what I should do to fix that?

 

Thanks in advance,

Quentin

Hello Quentin,

The search functionality in our MultiColumnComboBox treats the symbols "+", "-" and ":" as special characters. You can find their descriptions here. Practically this sub feature works the same way in the GridView's search-as-you-type feature and the multi column combo box control but this information is missing in our documentation and we will address it soon.
In your case to detect values starting with - you need to use double quotes "-yoursearchstring", consider this is like escaping the minus in the quotes.
Let me know your thoughts on this feature, we would be glad to receive any feedback regarding it.

Hi Petar,

Thanks for your response, it makes more sense to me now. After reading it, I think that being able to change the searching criteria with those special characters makes sense and can be useful in certain situations. However in my case this is quite annoying because all my items start with the "-" character. So I would be very interested to have the option to de-activate the special character.

Cheers,

Quentin
