C# WPF Binding to DataBase -


hei all. if not clear please tell

i have datagrid , treeview. have loaded data base entity data model , tables. 1 of these tables "relation" should show datagrid. (relation table) column depend of other tables system,model,function , device. in data grid should 4 columns contain names of these system,model,function , device. (the picture 1 should be)

problem in how show. datasource don't work well... see picture 2.

<grid datacontext="{staticresource relationsviewsource}">         <datagrid autogeneratecolumns="true" name="gridinventory" horizontalcontentalignment="right" margin="255,12,12,128" itemssource="{binding}" />         <stackpanel height="391" horizontalalignment="left" margin="10,10,0,0" name="stackpanel1" verticalalignment="top" width="239" datacontext="{staticresource systemsviewsource}" >             <treeview height="391" name="treeview1" width="239" verticalcontentalignment="top" horizontalalignment="left" verticalalignment="top" itemssource="{binding}" />         </stackpanel>     </grid>

you binding both treeview , of datagrid columns object, not telling wpf how draw object. when wpf doesn't know how draw object, default draws using textblock text bound object's .tostring()

you need set itemtemplate tell wpf how draw individual objects, such this:

<treeview.itemtemplate>     <datatemplate>         <textblock text="{binding name}" />     </datatemplate> </treeview.itemtemplate>

you use implicit datatemplate tell wpf how draw specific objects. datatemplate specifies datatype without key, , wpf use anytime tries render object of specified type.

if want avoid removing autogeneratecolumns="true" , manually specifying datagrid's columns, method use.

<datagrid.resources>     <datatemplate datatype="{x:type local:device}">         <textblock text="{binding name}" />     </datatemplate> </datagrid.resources>
