combobox - WPF combo box update source trigger -


i've added triggers combobox, i.e.

  • when combo box 'disabled' 'text' property should set '1' , added updatesourcetrigger property changed.

  • when combo box 'enabled' 'text' property should selected 1 , added update source trigger property changed.

but problem i'm unable call update source trigger when combo box disabled , 'text' property set '1'.

below xaml code snippet:

<combobox name="cmbintervals"                         grid.row="5"                         grid.column="1"                         width="150"                         horizontalalignment="left"                         verticalalignment="top"                         isenabled="{binding elementname=chkrollinginterval,                                               path=ischecked}"                         itemssource="{binding source={x:static es:masterparameters.instance},                                                 path=noofintervals}"                          tag="{binding path=[noofintervals], mode=twoway, updatesourcetrigger=propertychanged}"                         >                   <combobox.style>                     <style targettype="{x:type combobox}">                       <style.triggers>                         <trigger property="isenabled" value="false">                         <setter property="text" value="1"/>                         <setter property="text" value="{binding relativesource={relativesource self}, path=tag, mode=twoway, updatesourcetrigger=default}"/>                       </trigger>                       <trigger property="isenabled" value="true">                         <setter property="text" value="{binding relativesource={relativesource self}, path=tag, mode=twoway, updatesourcetrigger=propertychanged}"/>                       </trigger>                       </style.triggers>                    </style>                 </combobox.style>               </combobox>

from above xaml code when ever updated 'text' property '1' combo box 'disabeld' mode need update '1' value source property i.e. 'tag' , there 'noofintervals' doesn't happening.

thanks, nag

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
