As far as I know, this is not possible with normal syntax but you can do one thing.
1. Create a separate js file for Javascript code
2. Give reference to that file in both the aspx files

HTML

<script src="yourscript.js"></script>

3. Now you can all the functions contained in the js file

To call Javascript function fro code behind :

C#

Page.ClientScript.RegisterStartupScript(this.GetType(), "Script", "YourJSFunction();", true);

Hopefully, it helps :)

Solution 1

You make first External javascript file. And call this file on page .
like this:
<script type="text/javascript" src="../page/file.js"></script>
Ex.

Code Behind

protected void DoSomethingButton_Click(object sender, EventArgs e)
{ScriptManager.RegisterStartupScript(this, Page.GetType(), "key", "MyFunc()", true);
}

this is not working because in the second page I want to set values of textboxes from parameters passed in the call statement

If you want to set textboxes in the new page then you should pass the parameters using querystring or session or viewstate. This will help you rather banging your head in some infeasible solutions.

ok, you use parameters function then you make condition in external js file according your parameter.
