I'm a long-time C++ programmer transitioning to C#/XAML and am porting over a grid-based C++ application and am finding it extremely difficult to make the grid changeable. Does anyone know of an easy way to do this? Also, since the C++ grid I used had effortless 2-way editing what does that say about the overhead and complexity needed to accomplish the same task in XAML/WPF? Here's some sample code illustrating my dilema. Thank you.

<listview grid.row="5" grid.columnspan="6" itemssource="{Binding optionPositionCollection}" selecteditem="{Binding SelectedOptionPosition}"
                  Grid.Column="0"
                  VerticalAlignment="Stretch" HorizontalAlignment="Stretch" removed="LightCyan">
            <listview.itemcontainerstyle>
                <Style TargetType="{x:Type ListViewItem}"/>
           </listview.itemcontainerstyle>

            <listview.view>
                <gridview>
                    <gridview.columns>
                        <!--Call info-->
                        <gridviewcolumn header=" Strike " width="auto"
                                    DisplayMemberBinding="{Binding Path=Strike}"/>
                        <gridviewcolumn header=" Volatility " width="auto"
                                    DisplayMemberBinding="{Binding Path=SkewVolatility}"/>
                        <gridviewcolumn header=" Calls " width="auto"
                                    DisplayMemberBinding="{Binding Path=CallPosition}"/>
                        <gridviewcolumn header=" Call Settle " width="auto"
                                    DisplayMemberBinding="{Binding Path=CallSettle}"/>
                        <gridviewcolumn header=" Call Theo " width="auto"
                                    DisplayMemberBinding="{Binding Path=CallTheo}"/>
                        <gridviewcolumn header=" Excess " width="auto"
                                    DisplayMemberBinding="{Binding Path=CallExcess}"/>
                        <!--Put info-->
                        <gridviewcolumn header=" Strike " width="auto"
                                    DisplayMemberBinding="{Binding Path=Strike}"/>
                        <gridviewcolumn header=" Puts " width="auto"
                                    DisplayMemberBinding="{Binding Path=PutPosition}"/>
                        <gridviewcolumn header=" Put Settle " width="auto"
                                    DisplayMemberBinding="{Binding Path=PutSettle}"/>
                        <gridviewcolumn header=" Put Theo " width="auto"
                                    DisplayMemberBinding="{Binding Path=PutTheo}"/>
                        <gridviewcolumn header=" Excess " width="auto"
                                    DisplayMemberBinding="{Binding Path=PutExcess}"/>
                    
                </gridview>
            </listview.view>
        </listview>
