I am building a user registration form in asp.net. I want to check if the username is available or not on the leave event of the TextBox. I am not able to get the Leave Event of the TextBox.
Should I use OnBlur event of the Html TextBox.
I don't need to run the function every time the page loads!!
But, I would like to have the control when the function is to be called.
The only way I thought of is calling my function with OnLoad in the body tag and having a hidden field to be checked and then run the script accordingly.
e.g:
<body onload="ScrollToView();">
Is there a better way? For example, running the function from Page_InitComplete handler?
I have a javascript function on my Master page, how do I access it with a dropdownlist of a content page. Not from codebehind, I can do that, but from the control itself such as the onSelectedIndexChanged event.

I am writing an ASP.Net application. I am making use of master page in it. I have several child pages with me, which consist of some java script functions; Let's say;
function ChildPageFunction()
{
//Do something;
}
And master page java script function as;
function MasterPagefunction()
{
//Need to call ChildPagefunction(); here
}
Now is it possible to call ChildPageFunction() from MasterPageFunction()?
I have a confusion regarding ajax call.when an ajax call is done why is it so that a page load event is fired when its not a ful page request.
My understanding is that a page load event should not be called on an asynchronous postback.
Can any1 explain me why this is happening?
here is the code:
aspx page:
[Code]....
aspx.cs page:
[Code]....
In GridViewData.aspx.cs I have a method I want to call inside a javacsript function.

Now hears the kicker, I am mostly using jqUery as UpdateInsertData() is a jquery Call and works fine. How do I use ValidateNameUpdateable to call jQuery to return the value from the c# method. . I believe this issue is with my jQuery Call as its just posting and I need to do a $.get or something?
function ValidateNameUpdateable()
{
$(document).ready(function ()
{
$.post("GridViewData.aspx")
});
}
