wpf - How to get DataTemplate to fill DataGridTemplateColumn -

-

i have following xaml creating datagrid:

<datagrid canuseraddrows="false" horizontalalignment="left" name="test" autogeneratecolumns="false" height="164" margin="205,264,0,0" verticalalignment="top" width="511">         <datagrid.columns>             <datagridtextcolumn canusersort="false" binding="{binding description, mode=twoway}" header="description" width="6*" isreadonly="true" />             <datagridtemplatecolumn width="2.6*" x:name="parent" >                 <datagridtemplatecolumn.headertemplate>                     <datatemplate >                         <grid showgridlines="false" width="{binding elementname=parent,path=width}" >                             <grid.columndefinitions>                                 <columndefinition width="1*" />                                 <columndefinition width="1*" />                             </grid.columndefinitions>                             <textblock text="initial " grid.column="0" />                             <textblock text="date " grid.column="1"  />                         </grid>                     </datatemplate>                 </datagridtemplatecolumn.headertemplate>                 <datagridtemplatecolumn.celltemplate>                     <datatemplate>                                                   </datatemplate>                 </datagridtemplatecolumn.celltemplate>             </datagridtemplatecolumn>             <datagridcheckboxcolumn canusersort="false" binding="{binding stepcomplete, mode=twoway}" header="completed" width="1.5*" isreadonly="true" />         </datagrid.columns>     </datagrid>

i have created datagridtemplatecolumn.headertemplate datatemplate inside want create multi header column. issue cannot datatemplate stretch / fill parent cell. have added image below demonstrate problem. please note area highlighted around initial date text datatemplate border. know how can change datatemplate fill parent cell?

thanks callum

enter image description here

to set header cell alignment have use columnheaderstyle:

<datagrid.columnheaderstyle>     <style targettype="{x:type datagridcolumnheader}">         <setter property="fontweight"  value="bold" />         <setter property="horizontalalignment" value="stretch" />         <setter property="horizontalcontentalignment" value="stretch" />     </style> </datagrid.columnheaderstyle>

i see 2 issues in code:

  1. you trying binding grid.width property (double) datagridtemplatecolumn.width property value 2.6* (datagridlength). cannot set 2.6* grid.width, because not valid double value.
  2. datatemplate has own namescope, therefore cannot refer element outside datatemplate using elementname. moreover, datagridtemplatecolumn not uielement , not in visualtree, therefore datagridtemplatecolumn not parent of elements defined in datatemplate. datagridtemplatecolumn used define columns. datagrid generate headers, rows , cells based on definitions, datagridcolumns never gets rendered.

asp.net - 'System.Web.HttpContext' does not contain a definition for 'GetOwinContext' Mystery -

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana...

mercurial graft feature, can it copy? -

-
there new feature in mercurial 3, called 'graft' (graft local). job of moving change-set different branch. is there way "copy" change-set branch? i interested in in moving stuff qa branch production branch, still need code reside in qa. want copy. found , have tried few things, maybe it'll become clear more tinkering , reading... does have better way of 'cherry picking' change-sets move cross branch (or trunk)??? graft copies changesets, doesn't move them. hg graft (emphasis mine): this command uses mercurial's merge logic copy individual changes other branches without merging branches in history graph. known 'backporting' or 'cherry-picking' . default, graft copy user, date, , description source changesets.
