推荐答案
<asp:ImageButton ID="ImageButton2" runat="server" src="Images/logout.png"
Height="22px" Width="80px" onclick="ImageButton2_Click" />
In asp u have to use ImageUrl instead of src
In asp u have to use ImageUrl instead of src
<asp:ImageButton ID="ImageButton2" runat="server" ImageUrl="Images/logout.png"
Height="22px" Width="80px" onclick="ImageButton2_Click" />You are getting error due to following reasons:
1. Your master doesn’t contain any form tag. And you are using server side control without any form runat=\"server\".
2. If it is really necessary to use image button in master then you can add form tag in master page with run at server. Add image button inside it. Remove form tag in child pages other otherwise it will throw you error that page cannot contain multiple form tag.

Instead of adding form tags in aspx page add it in master page only.
Add master page all the body content inside form tag with runat server. And provide closing tags for labels in master page file.
In the master page file you have written like
asp:ContentPlaceHolder with id=\"head\" and it needs to be closed before close of the head tag.
In the last added lines like
asp:Panel ID=\"panel1\"
iside
asp:ContentPlaceHolder id=\"ContentPlaceHolder1\"
provide closing tags respectively.
