c# - onkeyup event asp.net -

-

hi how can register , call server side event onkeyup event in asp.net textbox.

is possible?

thank you

textbox web control doesn't provide onkeyxxx events instead subscribe ontextchanged event;

<asp:textbox id='textbox1' runat='server' ontextchanged='handletextbox1ontextchanged'>     </asp:textbox>  public void handletextbox1ontextchanged(object sender, eventargs e)     {      }

but can provide onkeyxxx behavior client-side.

you can add client-side handler :

textbox1.attributes.add("onkeyup", string.format("onkeyup({0})", textbox1.id));

and in page 

`<script language='javascript' type='text/javascript'>    function onkeyup(id) { //do something; }  </script>`

also use pagemethods make call server-side web methods (static methods) javascript functions.

this link might help.

binding - How can you make the color of elements of a WPF DrawingImage dynamic? -

-
we have need make vector graphic images change color of elements within graphic @ runtime. seem setting colors based on either static or dynamic resource values wouldn't work. want have multiple versions of same graphic, each abilty set graphic elements (path, line, etc) different colors don't think dynamic resource approach work. leaves data binding seems right approach. update graphic use data binding expr instead of hard-coded brush color so: <drawingimage x:key="graphic1"> <drawingimage.drawing> <drawinggroup> <drawinggroup.children> <geometrydrawing geometry="f1 m 8.4073,23.9233l"> <geometrydrawing.pen> <pen linejoin="round" brush="{binding line1brush, mode=oneway}"/> </geometrydrawing.pen> </geometrydrawing> <geometrydrawing geometry="f1 m 3.6875,2.56251l"> <geometrydrawing....
