c# - ListView showing System.Data.DataRowView instead of DataTable -

my problem every row of listview shows "system.data.datarowview" after change listview template style.

i've defined datatable here:

datatable data = new datatable(); lsvoutput.itemssource = data.defaultview; 

this xaml columns:

            <listview.view>                 <gridview>                     <gridviewcolumn header="column1" displaymemberbinding="{binding column1}"/>                     <gridviewcolumn header="column2" displaymemberbinding="{binding column2}"/>                     <gridviewcolumn header="column3" displaymemberbinding="{binding column3}"/>                 </gridview>             </listview.view> 

this part breaks i'm assuming:

                    <contentpresenter                         horizontalalignment="{templatebinding horizontalcontentalignment}"                          verticalalignment="{templatebinding verticalcontentalignment}"                         snapstodevicepixels="{templatebinding snapstodevicepixels}"/> 

i figured out. replaced this:

<contentpresenter                     horizontalalignment="{templatebinding horizontalcontentalignment}"                      verticalalignment="{templatebinding verticalcontentalignment}"                     snapstodevicepixels="{templatebinding snapstodevicepixels}"/> 

with this:

<gridviewrowpresenter verticalalignment="{templatebinding verticalcontentalignment}" />
