silverlight - SL4 - TextTrimming in DataGridRowGroupHeader -

-

i'm customizing datagridrowgroupheader in our project. works fine except can't text trim.

here's style:

            <sdk:datagrid.rowgroupheaderstyles>             <style targettype="sdk:datagridrowgroupheader">                 <setter property="cursor" value="arrow" />                 <setter property="istabstop" value="false" />                 <setter property="background" value="transparent" />                 <setter property="height" value="20"/>                 <setter property="margin" value="18,0,20,0"/>                 <setter property="isenabled" value="false"/>                 <setter property="template">                     <setter.value>                         <controltemplate targettype="sdk:datagridrowgroupheader">                             <grid name="root"                                  margin="{templatebinding margin}"                                 background="{templatebinding background}"                                 horizontalalignment="stretch"                                 >                                 <visualstatemanager.visualstategroups>                                     <visualstategroup x:name="currentstates">                                         <visualstate x:name="regular"/>                                         <visualstate x:name="current">                                             <storyboard>                                                 <doubleanimation storyboard.targetname="focusvisual" storyboard.targetproperty="opacity" to="1" duration="0" />                                             </storyboard>                                         </visualstate>                                     </visualstategroup>                                 </visualstatemanager.visualstategroups>                                  <border borderbrush="yellow" borderthickness="1" visibility="visible">                                  <textblock x:name="txbgroupingname"                                     margin="4,0,0,0"                                      text="{binding name}"                                      fontsize="13"                                      texttrimming="wordellipsis"                                     horizontalalignment="left"                                     style="{staticresource orangebodytext}"                                     />                                  </border>                                  <rectangle name="focusvisual"                                      stroke="{staticresource borderfocusbrush}"                                      strokethickness="1"                                      horizontalalignment="stretch"                                      verticalalignment="stretch"                                      ishittestvisible="false"                                      opacity="0" />                              </grid>                         </controltemplate>                     </setter.value>                 </setter>             </style>         </sdk:datagrid.rowgroupheaderstyles>

the text in textblock txbgroupingname won't trim , seems should fine.

thanks in advance!

i got answer yifung lin. rowgroupheader fixed width of row. it's intended horizontal scrollbar appears when datagrid content long, , rowgroupheaders can viewed way. it's when columns frozen problem appears.

thus there no solution really, reason why text won't trim dynamically. width can set on textblock force trimming, work better wrapping.

binding - How can you make the color of elements of a WPF DrawingImage dynamic? -

-
we have need make vector graphic images change color of elements within graphic @ runtime. seem setting colors based on either static or dynamic resource values wouldn't work. want have multiple versions of same graphic, each abilty set graphic elements (path, line, etc) different colors don't think dynamic resource approach work. leaves data binding seems right approach. update graphic use data binding expr instead of hard-coded brush color so: <drawingimage x:key="graphic1"> <drawingimage.drawing> <drawinggroup> <drawinggroup.children> <geometrydrawing geometry="f1 m 8.4073,23.9233l"> <geometrydrawing.pen> <pen linejoin="round" brush="{binding line1brush, mode=oneway}"/> </geometrydrawing.pen> </geometrydrawing> <geometrydrawing geometry="f1 m 3.6875,2.56251l"> <geometrydrawing....
