c# - Bind DataGridTextColumn to method WPF -

is possible bind datagridtextcolumn method in xaml.cs?

this xaml

           <my:datagrid.columns>                 <my:datagridtextcolumn binding="{binding iditem}" header="id item" width="150" isreadonly="true"/>                  <my:datagridtextcolumn binding="{binding concatenarmoneda}" header="costo" width="*"/>             </my:datagrid.columns> 

and want bind second column following function

private string concatenarmoneda     {         {              return viewmodel.registro.costo.tostring() + " " + viewmodel.registro.sosmoneda.descripcion;          }     } 

this should result in 2 properties being concatenated in same column

i have seen working textblock not working in case.

see bind property method

this whole grid

  <grid grid.row="2" background="{dynamicresource grisoscuro}">         <my:datagrid enablerowvirtualization="false" x:name="datagriddatos" margin="32"                      horizontalalignment="stretch" verticalalignment="stretch"                       autogeneratecolumns="false" background="white"                                          selectionchanged="datagriddatos_selectionchanged"                      selecteditem="{binding registro}"                      itemssource="{binding registros}"                      isenabled="{binding datagriddatosestado}"                      selectedindex="{binding indiceactual}"                      isreadonly="true">             <my:datagrid.columns>                 <my:datagridtextcolumn binding="{binding iditem}" header="id item" width="150" isreadonly="true"/>                 <my:datagridtextcolumn binding="{binding sosproveedor.nombre}" header="proveedor" width="150" isreadonly="true"/>                 <my:datagridtextcolumn binding="{binding sosservicio.descripcion}" header="servicio" width="*"/>                 <my:datagridtextcolumn binding="{binding sosubicacion.descripcion}" header="ubicacion" width="*"/>                 <my:datagridtextcolumn binding="{binding sostipopagoitem.descripcion}" header="tipo pago item" width="*"/>                 <my:datagridtextcolumn binding="{binding fechainiciovigencia , stringformat={}{0:dd/mm/yy}}" header="fecha inicio" width="*"/>                 <my:datagridtextcolumn binding="{binding estatus}" header="estatus" width="*"/>                 <my:datagridtextcolumn  binding="{binding relativesource={relativesource findancestor, ancestortype={x:type window}},              path=concatenarmoneda,mode=oneway}" header="costo" width="*"/>             </my:datagrid.columns>         </my:datagrid>     </grid> 

that grid sorrounded parent element within xaml

on other in xaml.cs i've got concatenarmoneda function showed above

and viewmodel brings data model... using methods such this

public observablecollection<sositem> items     {                 {             if (_items == null)             {                 _items = new observablecollection<sositem>(db.sositems.select(approw => approw));             }             return _items;         }         set         {             _items = value;             notifypropertychanged("items");         }     } 

maybe ancestor type suggest should other

  ancestortype={x:type window} 

?

you need use imultivalueconverter gerthermans mentioned.

 <datagridtextcolumn  width="70" header="costo">                 <datagridtextcolumn.binding>                     <multibinding converter="{staticresource concatconverter}">                         <binding path="costo" />                         <binding path="sosmoneda.descripcion" />                     </multibinding>                 </datagridtextcolumn.binding>             </datagridtextcolumn>     public class concatconverter : imultivalueconverter         {             public object convert(object[] values, type targettype, object parameters, cultureinfo culture)             {                 return values[0].tostring() + " " + values[1].tostring();             }                public object[] convertback(object value, type[] targettypes, object parameter, system.globalization.cultureinfo culture)             {                 throw new notimplementedexception();             }         }
