c# - Vertical Grouping - WPF DataGrid or ListView -


how can have below view using wpf or creating custom control?

datgrid

as need use data templates , cell values might object instances, cannot use winforms use old structure. (not mention if wouldn't!)

grouping level can 1 (like picture) or more. 4 steps satisfactory here.

any other solutions appreciated.

here go

i defined itemscontrol bound items (your data) , defined group style show data expectation.

    <itemscontrol itemssource="{binding items}">         <itemscontrol.groupstyle>             <groupstyle>                 <groupstyle.containerstyle>                     <style targettype="{x:type groupitem}">                         <setter property="template">                             <setter.value>                                 <controltemplate targettype="{x:type groupitem}">                                     <grid>                                         <grid.columndefinitions>                                             <columndefinition width="auto" />                                             <columndefinition />                                         </grid.columndefinitions>                                         <border borderbrush="black" borderthickness=".5" padding="4">                                             <textblock text="{binding name}" verticalalignment="center" />                                         </border>                                         <itemspresenter grid.column="1" />                                     </grid>                                 </controltemplate>                             </setter.value>                         </setter>                     </style>                 </groupstyle.containerstyle>             </groupstyle>         </itemscontrol.groupstyle>         <itemscontrol.itemtemplate>             <datatemplate>                 <border borderbrush="black" borderthickness=".5" padding="4">                     <textblock text="{binding data}" />                 </border>             </datatemplate>         </itemscontrol.itemtemplate>     </itemscontrol>

here code prepare groups

        items = new observablecollection<item>();         items.add(new item() { key = "abcd", data = 1 });         items.add(new item() { key = "abcd", data = 2 });         items.add(new item() { key = "qwer", data = 1 });         items.add(new item() { key = "qwer", data = 2 });          collectionview view = (collectionview)collectionviewsource.getdefaultview(items);         propertygroupdescription groupdescription = new propertygroupdescription("key");         view.groupdescriptions.add(groupdescription);

after leave wpf , enjoy power of styling , binding

multilevel grouping

to achieve miltilevel grouping need add propertygroupdescription view.groupdescriptions

eg

groupdescription = new propertygroupdescription("key2"); view.groupdescriptions.add(groupdescription);

multilevel group sample

there no limit of sub group can create, need key group.
