Hello,
I'm a newbie to WPF and having troubles to figure out how to hide or show a column based on its data

I currently have a list view as

<listview>
     <listview.view>
       <gridviewcolumn header="Code " width="50">
          <gridviewcolumn.celltemplate>
              <datatemplate>
                    <textblock text="{Binding Path=Code}" textalignment="Center" />
               </datatemplate>
          </gridviewcolumn.celltemplate>
       </gridviewcolumn> 
 
        <gridviewcolumn header="" width="20">
            <gridviewcolumn.celltemplate>
               <datatemplate>
                   <textblock text="{Binding Path=CodeType}" textalignment="Center" />
                                                   
                                    </datatemplate>
                                </gridviewcolumn.celltemplate>
                            </gridviewcolumn>
</listview.view>
</listview>

I tried not to display the CodeType column when the data in the column is U and show it when data is S after I dynamically changed to datasource (ListView.dataContext = ds.Tables(0) .....ete)
for ex: my listview could show like:

Code CodeType
1-Empty S
2-Liquid
3-Rock S

the 2-Liquid has code type of U and not show U here.

Read lots of article here but still having errors and could not complete it.
Please let me know if you have an answer. Thanks a lot.
