I need to know how to trigger a postback from one aspx page to another

Question

I have a one.aspx page that is running and I need to trigger a postback on two.aspx. Can this be done? If so, how?

Answer 1

The simple and archaic method is probably this: define a <form> element, set method attribute to "post", set action attribute to the target two.aspx address, and maybe make it hidden using styles. Then insert a series of <input type= “hidden” name=“…” value =“…”/> elements, which will hold the parameters to be passed to two.aspx.

In order to post the data, use submit() function of <form> element using JavaScript. For example:

<form id="form1" method="post" action="two.aspx">
   <input type="hidden" name="param1" value="value1"/>
</form>

In JavaScript:

document.getElementById("form1").submit().

ASP.NET Web Forms has such function so called the cross-page post back. If you use the control such as the Button, LinkButton and ImageButton in one.aspx to move to two.aspx set the URL of two.aspx to the PostBackUrl property of the control.

For detail, refer to the following Microsoft document:
