GetPostBackEventReference(Control, String)
Returns a string that can be used in a client event to cause postback to the server. The reference string is defined by the specified control that handles the postback and a string argument of additional event information.

5.
使用ScriptManager.RegisterStartupScript方法可注册一个每次发生异步回发时都将包括的启动脚本块。 若要为 UpdatePanel 控件内的某个控件注册一个脚本块，以便仅在更新 UpdatePanel 控件时才注册该脚本块，请使用该方法的 RegisterStartupScript(Control, Type, String, String, Boolean) 重载。

如果要注册与部分页面更新无关的启动脚本，并且只想在初始页面呈现期间注册一次该脚本，请使用 ClientScriptManager 类的 RegisterStartupScript 方法。 可以从页面的 ClientScript 属性获取对 ClientScriptManager 对象的引用。

if (!ClientScript.IsClientScriptBlockRegistered("exampleScript"))
ClientScript.RegisterStartupScript(this.GetType(), "exampleScript","

");

Script to hide status bar messages in IE
onmouseover="window.status=''; return true;" OnClientClick="location.href='/Login.aspx'"

7.
//right click disabled
$(document).bind("contextmenu",function(e){
return false;
});

$(document).bind("keydown", function(e) {
//backspace
if (e.keyCode == 8) return false;
});

8.

In basepage, define ExecuteClientScript method:
public void ExecuteClientScript(StringBuilder scriptJs)
{
ClientScript.RegisterStartupScript(typeof(string), "script", scriptJs.ToString(), true);
}


From code behind:
ExecuteClientScript(new StringBuilder(" CloseMapOverlay(); "));

In page:
script type="text/javascript">
function CloseMapOverlay()
{
parent.$.fancybox.close();
}
/script>

9. From javacript, run sever side event handler:
$("li.dropdown ul li a").live("click", function ()
{
$('#hdnProvince').val($(this).attr("id"));
$('#btnSaveCookie').click(); //here call server side event handler
return false;
});

This is the button that has onclick event



10. Call webservice from javascript

Method RegisterFirstAccess is defined in Default.aspx.cs.

[WebMethod()]
public static void RegisterFirstAccess()
{
//Registering the first access to call the map overlay
HttpContext.Current.Session.Add("FirstAccess", "false");
}

From jquery:

if (IsFirstAccess == 'true') {

//registering the first access with user session...
$.ajax({
type: "POST",
url: "Default.aspx/RegisterFirstAccess",
data: "{}",
contentType: "application/json; charset=utf-8",
dataType: "json"
});
