binding - Add extra column to WPF DataGrid which is not in the collection -

-

i'm using datagrid control display content of datatable. therefore data table set itemssource of datagrid.

following columns of datagrid represent columns of data table:

type, name, domain, subdomain

now dynamic column, called "properties" should contain specific information, depending on value of "type" column. this:

switch (type)     case abc:   content="row.field1"     case def:   content="row.field2"     case xyz:   content="row.fieldx"

where field1 .. fieldx columns data table. i'm using datagrid bindinglistcollectionview. best if solution build on this.

i tried multivalue binding , multivalue converter have more freedom , not having pre-select fields:

var bind = new multibinding();  bind.bindings.add(new binding("protocol")); bind.bindings.add(new binding("path1")); bind.bindings.add(new binding("path2")); bind.bindings.add(new binding("path3")); bind.bindings.add(new binding("path4"));  bind.converter = _configurationmultivalueconverter;  col.binding = bind;

you use that. of course it's example.

public class yourclass {     public yourtype protocol;     public yourtype2 path1;     public yourtype3 path2;     public yourtype4 path3;     public yourtype5 path4;     public int chooseexpression;     public yourtype6 field1;     public yourtype7 field3;     public yourtype8 fieldx; }

and in datagrid

<datagrid name="ifyouneedaname" autogenneratecolumn="false" itemssource={binding yourclass} >     <datagrid.columns>         <datagridtextcolumn header="protocolheader" binding={binding protocol} />         <datagridtextcolumn header="path1header" binding={binding path1} />         ...         <datagridtextcolumn header="thechoosenone" binding={binding yourclass, yourbindingconverer} />     </datagrid.columns> </datagrid>

and @ last converter, inherit ivalueconverter

public class yourbindingconverer : ivalueconverter {     public object convert(object value, type targettype,          object parameter, cultureinfo culture)     {         switch(value.chooseexpression)             case 1: return field1.tostring();             case 2: return field3.tostring();             case 3: return fieldx.tostring();         else             return string.empty;         end;     }      public object convertback(object value, type targettype,          object parameter, cultureinfo culture)     {         throw new notimplementedexception();     } }

i've wrote memory, becasue don't have vs here. think, that. if have more questions, feel free ask.

and bonus, here solution value converters.
