c# - How do I call a JavaScript function from my code behind, the function being on a separate .js file? -


this question has answer here:

code behind:

protected void page_load(object sender, eventargs e) {       page.clientscript.registerclientscriptblock(gettype(), "mykey", "createnotificationtree(" + userid + ")", true); }

.js file:

function createnotificationtree(userid) {     var data = new kendo.data.hierarchicaldatasource({         transport: {             read: {                 url: "../api/notifications/byuserid/" + userid,                 contenttype: "application/json"             }         },         schema: {             model: {                 children: "notifications"             }         }     });      $("#treeview").kendotreeview({         datasource: data,         loadondemand: true,         checkboxes: {             checkchildren: true         },         datatextfield: ["notificationtype", "notificationdesc"]     }); }

markup (do need this?):

<script type="text/javascript">             $(document).ready(createnotificationtree(userid)); </script>

this not working. treeview not loaded on page.

in script block not assigning createnotificationtree called on $(document).ready, call right there. correct way is:

<script type="text/javascript">    $(document).ready(function () {       createnotificationtree(<%= this.userid.tostring() %>);    }); </script>

then don't need registerclientscriptblock in page_load.

the second option not use $(document).ready, call registerstartupscript (which writes script @ bottom of page, when dom elements available) instead of registerclientscriptblock in page_load.

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)...
