Javascript code execute through .cs file.

Hi

There are different ways to call JS from CS.

First is you can use attribute property as below,

btnHide.Attributes.Add("onclick", "return hideButton()"); this is in page load.so when your button click,then first it will call your client side function which is JS.

Second you can call using below

string javaScript =
  "";
 
 RegisterStartupScript("Button1_ClickScript", javaScript); you can register the script.

Hope this helps

Thanks
