Windows Phone ListBox in two columns

To get a ListBox with multiple columns, each unit is an item of ListBox, as shown below:

 

Corresponding XAML:

                     <  Grid  X: Name  = "Loginnosubspanel"  Visibility  = "Visible"  >                          <  ListBox  X: Name  = "Hotkeywordslistbox"  Itemssource  =" {Binding recommendedtopicsleft}  "  >                              <  ListBox. itemspanel  >                                  <  Itemspaneltemplate  >                                      <  Toolkit: wrappanel  Itemheight  = "176"  Itemwidth  = "176"  />                                 </  Itemspaneltemplate  >                              </  ListBox. itemspanel  >                              <  ListBox. itemtemplate  >                                  <  Datatemplate  >                                      <  Grid  Margin  = "20, 0, 0, 20" >                                          <  Grid. rowdefinitions  >                                              <  Rowdefinition  Height  = "Auto"  />                                              <  Rowdefinition  Height  = "*"  />                                          </  Grid. rowdefinitions  >                                         <  Image  Grid.
