If you are working with AJAX UpdatePanel, following code should work for you. In my case, I was using update panel and none of the about worked except this one.

C#

ScriptManager.RegisterStartupScript(myUpdatePanelID, myUpdatePanelID.GetType(), "myFunction", "myFunction();", true);

You can get more details from calling javascript function within ajax updatepanel[^]

Hope it helps you!
