Using a UniformGrid inside of a Button control in WPF -

-

i want content of button control contain uniform grid. however, button control doesn't seem allow child content control stretch. uniformgrid squeezed down fit own contents. allows me set width, won't auto stretch if set horizontalalignment explicitly. missing?

        <button margin="0,4,0,4">             <itemscontrol itemssource="{binding zones}" focusable="false">                 <itemscontrol.itemspanel>                     <itemspaneltemplate>                         <uniformgrid columns="{binding zones.count}" />                     </itemspaneltemplate>                 </itemscontrol.itemspanel>                 <itemscontrol.itemtemplate>                     <datatemplate>                         <wpfapplication2:controllerzonecontrol datacontext="{binding}" />                     </datatemplate>                 </itemscontrol.itemtemplate>             </itemscontrol>         </button>

i can force width using following, seems hacky me.

 <uniformgrid width="{binding relativesource={relativesource ancestortype={x:type button}}, path=actualwidth}" columns="{binding zones.count}" />

of things forgot try...setting button's horizontalcontentalignment stretch fix.

i need hash algorithm produces 64-bit hash code ( long ) fewer collisions string.gethashcode() , fast (no expensive calls cryptographic functions). here's implementation of fnv still shows 3% of collisions after testing 2 million random strings. need number way lower. void main() { const string chars = "abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz!#@$%^&*()_+}{\":?><,./;'[]0123456789\\"; const int n = 2000000; var random = new random(); var hashes = new hashset<long>(); int collisions = 0; for(int = 0; < n; i++) { var len = random.next(chars.length); var str = new char[len]; (int j = 0; j < len; j++) { str[j] = chars[random.next(chars.length)]; } var s = new string(str); if(!hashes.add(get64bithash( s ))) collisions++; } console.writeline("collision percentage after " + n + " random strings: " + ((doubl
