Putting same Javascript function in every ASP.net page

Shikari Shambu

Hi,
I have an ASP.NET website that has pages that inherit from a BasePage. I
want all pages to have some common Javascript functions.

I tried doing the following

In the Base Page
protected System.Web.UI.HtmlControls.HtmlGenericControl body;

protected void Page_Load(object sender, System.EventArgs e)

{
body.Attributes.Add("onload","javascript:alert('He llo World')");

}

And, when I access the child page MyPage.aspx I get

Object reference not set to an instance of an object.

How do I add same javascript to the body onload tag of all my pages.

TIA

Hi,

Did you put runat=server in body tag,like <body id=Body runat=server>
or you may initiate a class before you use it,
HtmlGenericControl body = new HtmlGenericControl("body");

A lot of the times this happens, it's because you have the control
referenced in a class, but don't have the control defined in the actual ASPX
page. Make sure that on every page that inherits from this that the body tag
has a runat="server" attribute and you have set the id to "body". Otherwise
when it comes time to render it will have no idea where the tag is that it's
supposed to add an attribute to.

Hope this helps,
