Question

How do I execute Javascript after submission of an ASP.NET form?

For example, if I got a submit button click after submission of page then I want to display a DIV which I have hidden on page.

Answer 1

If you would only want to convert the hidden div to a visible one then that can be done on the server side. In the aspx, give the div an id and a runat=”server”. Then in the server side, set its display style attribute to ‘block’. For example, say the div is defined as

<div id="divTest" runat="server" style="display:none;">
        This is a div test
</div>

Then in the post event of the submit button you can set its style as given below:

divTest.Style["display"] = "block";

If you only want to emit scripts after the post then using the ScriptManager you could use:

ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "ScriptRegisterTest", "alert('Testing');", true);
