c# - Setting MaxWidth at runtime in WPF -



c# - Setting MaxWidth at runtime in WPF -

this .net 4.5 wpf question. trying set maxwidth of frameworkelement defined in xaml (specifically, expander) programmatically, i've tried

myframeworkelement.maxwidth = value myframeworkelement.setvalue(maxwidthproperty,value) -and- myframeworkelement.dispatcher.invoke(() => maxwidth = value);

no joy. when run through debugger, maxwidth stubbornly remains @ value specified @ compile-time in xaml. possible set maxwidth , maxheight @ runtime?

thanks.

try set maxwidth of command in double in code. example, textbox names txttest can set maxwidth below.

txttest.maxwidth=300.0;

in case of expander mechanism works properly. can show me xaml how have defined expander

c# wpf xaml .net-4.5
