WPF DataGrid Binding on Columns -

-

hope wasn't asked already, can't find answer. got viewmodel set datacontext in xaml. in viewmodel list< dealer>-property. dealer has properties should displayed in datagrid (as columns, not of them). tried implement this:

<grid x:name="mygrid" datacontext="{binding source={staticresource creategamevm}}"> ...    <datagrid name="dealerlist" autogeneratecolumns="false" itemssource="dealerlist">       <datagrid.columns>          <datagridtextcolumn header="id" width="30"  binding="{dealerid}" />                                  <datagridtextcolumn header="name" width="*" binding="{dealername}" />                              </datagrid.columns>    </datagrid> ... </grid>

in case propertychanged in viewmodel null, nothing updated when dealerlist changes. (but items in dealerlist, before setting datacontext displayed correctly). don't know how solve this.

bind observablecollection<dealer> on viewmodel instead. way automatically updated when collection changes.

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

razor - Is this a bug in WebMatrix PageData? -

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...
