How to bind a value to user control property?

Now on,I just got AG_E_PARSER_BAD_PROPERTY_VALUE.I think this is because I didn't do any thing to my bind property.Is there any thing I　can do?

                    <ListBox.ItemTemplate>
                        <DataTemplate>
                            <StackPanel Orientation="Horizontal">
                                <Image Name="imgSvrIco" Source="{Binding pic}"/>
                                <StackPanel Orientation="Vertical" Margin="2,2,2,10" Tag="{Binding tag}" MouseLeftButtonUp="StackPanel_MouseLeftButtonUp_1">
                                    <TextBlock Name="lbTitle"  Text="{Binding title}" Margin="0,0,0,0" FontWeight="Bold" />
                                    <TextBlock Text="{Binding text}" Visibility="{Binding textVisibility}"/>
                                    <StackPanel Orientation="Horizontal">
                                        <TextBlock Text="{Binding time}"/>
                                        <TextBlock Text=" By " />
                                        <!--<my:UserBrand Address="{Binding address}" />-->
                                    </StackPanel>
                                </StackPanel>
                            </StackPanel>
                        </DataTemplate>
                    </ListBox.ItemTemplate>

Insufficient info.

AG_E_PARSER_BAD_PROPERTY_VALUE exception contains exact pointer (i.e. line/position in the Xaml file) where the problem happened. Find it, identify the place in the Xaml code and try to fix it.

Secondly, even if you showed us the Xaml position, we could only check syntactic errors as you hide the semantics - the corresp. C# code.

You say "I am sure Binding expression is correct", but is often something easily overlooked, such as "address" instead of "Address". (Do you really use nonstandard naming conventions?)
