Based on your scenario, you can use RegisterClientScriptBlock[^] or RegisterStartupScript[^]

You need to inject script through code. Clientside Javascript is the way to raise a messagebox/popup/etc. Have a look at sample article here: How to Use RegisterClientScriptBlock & RegisterStartupScript[^]
