You never even really call Javascript from code behind. You generate script or register the script, which is, essentially, still generating the script in the HTTP response. The script is called in a browser, nowhere else.

Solution 1

just missed the semicolon I think.

C#

Page.ClientScript.RegisterStartupScript(this.GetType(), "Call my function", "overlay('Saved Succesfully ');", true);

or

C#

ScriptManager.RegisterStartupScript(this.Page, this.GetType(), "tmp", "<script type='text/javascript'>disp_confirm();</script>", false);

Use below code in C# where abc is your Javascript function.

ScriptManager.RegisterStartupScript(this, GetType(), "importingdone", "abc();", true);
