c# - How can I make the background color of a node in a TreeView goes all the way out to the right edge? -

how can make background color of node in treeview goes way out right edge?

background

i have treeview nodes have children gray. leaf nodes have icon descriptive text.

it's easy fix. unfortunately it'll require pretty code since you'll have re-template treeviewitem. treeviewitem's template looks this

<controltemplate targettype="{x:type treeviewitem}">     <grid>         <grid.columndefinitions>             <!-- expand/collapse togglebutton -->             <columndefinition minwidth="19" width="auto"/>             <!-- treeviewitem -->             <columndefinition width="auto"/>             <!-- children -->             <columndefinition width="*"/>         </grid.columndefinitions>         <grid.rowdefinitions>             <rowdefinition height="auto"/>             <rowdefinition/>         </grid.rowdefinitions>         <togglebutton x:name="expander" clickmode="press" ischecked="{binding isexpanded, relativesource={relativesource templatedparent}}" style="{staticresource expandcollapsetogglestyle}"/>         <border x:name="bd" borderbrush="{templatebinding borderbrush}" borderthickness="{templatebinding borderthickness}" background="{templatebinding background}" grid.column="1" padding="{templatebinding padding}" snapstodevicepixels="true">             <contentpresenter x:name="part_header" contentsource="header" horizontalalignment="{templatebinding horizontalcontentalignment}" snapstodevicepixels="{templatebinding snapstodevicepixels}"/>         </border>         <itemspresenter x:name="itemshost" grid.columnspan="2" grid.column="1" grid.row="1"/>     </grid>

as can see, treeviewitem in column 1 has width set auto while children (itemspresenter) in grid.column 1 , 2 , column 2 has width set *. treeviewitem same width children can remove middle column (column 1) , use grid.column="1" both.

here's default template treeviewitem "horizontal stretch" fix. you'll have add reference presentationframework.aero

</setter>         </trigger>     </style.triggers> </style>

and can use this

<treeview ...>     <treeview.itemcontainerstyle>         <style targettype="{x:type treeviewitem}" basedon="{staticresource stretchtreeviewitemstyle}">             <!-- add own setters if applicable -->         </style>     </treeview.itemcontainerstyle> </treeview>
