c# - Change column style depending of source -

i trying populate datagrid 1 column combobox need when collection binded combobox empty column becomes textbox column. have defined columns below:

binding binding = new binding("datacontext.prices"); binding.relativesource = new relativesource(relativesurcemode.findancestor, typeof(usercontrol),1);

datagridcomboboxcolumn productprices = new datagridcomboboxcolumn() {    elementsyle = new style    {         targettype = typeof(combobox),         setters =         {             new setter             {                 property=combobox.itemssourceproperty,                 value= binding             }         }    },    editingelementsyle = new style    {         targettype = typeof(combobox),         setters =         {             new setter             {                 property=combobox.itemssourceproperty,                 value= binding             }         }    },    displaymemberpath = new binding("price");    selectedvaluepath = new bindnt("price"); };  mydatagrid.columns.add(productprices); mydatagrid.columns.add(new datagridtextcolumn(){ header="name", binding=new binding("name")}); 

and defined mydatagrid:

<datagrid name="mydatagrid" itemssource="{binding products}" /> 

in viewmodel create

var products = new list<product> {     new product      {        name="prod 1",        price="12.5"     } } var prices = new list<pricel> {     new pricel     {        price="12.5"     },     new pricel     {        price="10"     }  }  icollectionview products = collectionviewsource.getdefaultview(products); icollectionview prices = collectionviewsource.getdefaultview(prices); 

i need when "prices" empty column become in textbox working mvvm , tried elementstyle cannot see event in combobox let me verify it's data source. body me ??

i found 1 way

<usercontrol.resources>     <datagrid itemssource={binding} x:key="datagrid1">         <datagrid.columns>             <datagridtextcolumn binding="{id}"/>             <datagridtextcolumn binding="{name}"/>         </datagrid.columns>     </datagrid>     <datagrid itemssource={binding} x:key="datagrid2">         <datagrid.columns>             <datagridtextcolumn binding="{id}"/>             <datagridcheckboxcolumn binding="{accepted}"/>         </datagrid.columns>     </datagrid>  </usercontrol.resources> <grid>     <contentcontrol content="{staticresource datagrid1}" datacontext="{binding mytable}" name="mycontent"/}     </grid> 

y por codigo puede cambiarse el content

mycontent.content = this.findresource("datagrid2");
