Windows StoreApp XAML: Changing ItemTemplate in GridView based on Data type -

i working on developing windows store app using c#/xaml. have experience in ios , extent android app development, not yet comfortable c#/xaml world.

here issue in gridview based page (based on nice template vs2012 generates).

i have gridview , collection bound data retrieved network , works fine. want change grid item depending on data. example: have files , folders show using different grid view items.

my question: how use different datatemplate itemtemplate depending on data? example, "folders", have 1 textblock vertically centered , file, have 2 textblocks , visually different.

am going right path or should doing different?

the xaml portion is

<gridview             x:name="itemgridview"             automationproperties.automationid="itemgridview"             automationproperties.name="grouped items"             grid.rowspan="3"             padding="116,137,40,46"             itemssource="{binding source={staticresource groupeditemsviewsource}}"             itemtemplate="{staticresource fileentriestemplate}"             itemclick="itemview_itemclick"             isitemclickenabled="true"             selectionmode="none"             isswipeenabled="false"> 

the template is

<datatemplate x:key="fileentriestemplate"> <grid horizontalalignment="left" width="400" height="80" background="beige">     <grid.columndefinitions>         <columndefinition width="80"/>         <columndefinition width="*"/>     </grid.columndefinitions>     <image source="{binding image}" stretch="uniform" grid.column="0" margin="10,0,0,0" automationproperties.name="{binding title}"/>      <stackpanel orientation="vertical" grid.column="1" background="transparent">         <textblock text="{binding title}" foreground="black" style="{staticresource largetitletextstyle}" margin="20,20,10,0"/>         <textblock text="{binding subtitle}" foreground="gray" style="{staticresource captiontextstyle}" textwrapping="nowrap" margin="20,10,0,30"/>     </stackpanel> </grid> 

gridview exposes through itemtemplateselector property class can create inherits datatemplateselector. example have gridview has issues , repositories bound , want use different data templates each.

my data template selector looks like:

public class issuesummarytemplateselector : datatemplateselector {     protected override datatemplate selecttemplatecore(object item, dependencyobject container)     {         return item issuegroupviewmodel ? issuetemplate : repositorytemplate;     }      public datatemplate repositorytemplate     {         get;         set;     }      public datatemplate issuetemplate     {         get;         set;     } } 

i declare selector resource in xaml assigning 2 templates want use repository , issues.

<selectors:issuesummarytemplateselector x:key="issuesummaryselector"                                         issuetemplate="{staticresource issuegridzoomedouttemplate}"                                         repositorytemplate="{staticresource issuegridrepositoryzoomedouttemplate}"/> 

you can use on gridview.

<gridview itemtemplateselector="{staticresource issuesummaryselector}" />
