Correct syntax for binding fields and character strings to server controls

1. <Asp: hyperlink id = "hyperlink1" visible = '<% # ismember & (bool) eval ("isopen") %>'
2. Cssclass = "sublistin" text = "[participate]" runat = "server"
3. Navigateurl = '<% # "/member/Editor/articlewrite _" + eval ("subjectid") + ". htm" %>'>
4. </ASP: hyperlink>

1. <Asp: literal runat = "server"
2. TEXT = '<% # "(recommended category:" + eval ("category. Name") + ")" %>'
3. Visible = '<% # eval ("isadscriptionimproper") %>'/>

I don't know why the added string cannot be written outside <% # eval ("") %> when the control is bound? Intuitively, it seems like this. I didn't want to write the string outside the bound string, but I couldn't correctly display what I want to achieve.

 

I asked the manager to know that the above statement is correct. However, the reason is unclear. Alas, I hope the experts can give an explanation ~

 

Thank you. Haha.
