wpf - DataTrigger C# in resourceDictionary -


i have searched topics on stackoverflow, none seem work me.

i set datagrid columns based on columns in resourcedictionary. (this dictionary consists of datagridtemplatecolumn's.) 1 of these columns contains binding boolean value. not want 'true' or 'false', want have '√' or ''.

this not seem work me (datatrigger textblock). still keeps 'true' or 'false'.

this textblock inside template:

<textblock text="{binding booleanvalue}" textalignment="center">     <textblock.style>         <style targettype="{x:type textblock}">             <style.triggers>                 <datatrigger binding="{binding booleanvalue}" value="true">                     <setter property="text" value="√"/>                 </datatrigger>                 <datatrigger binding="{binding booleanvalue}" value="false">                     <setter property="text" value=""/>                 </datatrigger>             </style.triggers>         </style>     </textblock.style> </textblock>

what missing or should change?

your datatrigger not change value of text property because set inside textblock declaration. so, once setted, never changed. allow changing, have set value inside style.
