Another way is to add style = "display: none;" to the button ;"

Another question was raised. To hide the code generated by button. Directly setting it to visible = false is as follows:
- <Input type = "hidden" name = "_ eventvalidation" id = "_ eventvalidation" value = "/wewagka94slagls0blrbspgcnzaq9b96g6xk5qxbfoy1i + k"/>
Therefore, use the following method.
- <Asp: button id = "button1" runat = "server" text = "button" onclick = "button#click" Height = "0px" width = "0px"/>
Someone asked me on the forum today. I tried it and succeeded. The friend gave me a full score. Well, record it and ask again.
