Ii. usage (note)

(1) Data Binding

<% # Databinder. eval (container. dataitem, "newsid") %>

(2) You only need to place it in a proper position (for example, passing it as a hyperlink parameter)
<A href = 'expertdetails. aspx? Newsid = <% # databinder. eval (container. dataitem, "newsid") %>'
(3) data format conversion (for example, date format conversion)
<% # (Datetime) databinder. eval (container. dataitem, "editdate"). tostring ("mm-dd") %>
(4) the output length of a string can be limited (C # built-in functions can be used)
<% # (String) databinder. eval (container. dataitem, "newstitle ")). substring (0, (string) databinder. eval (container. dataitem, "newstitle ")). length> 10? 10: (string) databinder. eval (container. dataitem, "newstitle"). Length) %>
(5) Cyclic logic (container. itemindex indicates the number of cycles currently)
<% # (Container. itemindex + 1) % 3 = 0 )? "</Tr> <TD Height = '8' width = '000000' colspan = '13' bgcolor = '# ffff'> </TD> </tr> <tr> ": "" %>

(6) When passing Chinese characters between pages, use system. Web. httputility. urlencode to convert and place garbled characters.

Href = '../news/news3.aspx? Moduleid = 500 & newsid = <% # databinder. eval (container. dataitem, "newsid") %> & Title = <% # system. web. httputility. urlencode (string) databinder. eval (container. dataitem, "newstitle") %>'

 

Two questions: (vs2003 is used)

1.

 

When the href = "href =" "corresponding to <A> </A> In the code is enclosed in double quotation marks, the message" failed to open in design view. In the <% value %> fast, enclose values in different ways "... this prompt is not displayed if it is changed to single quotes.

<A href = 'recorddetailinfo. aspx? Newsid = <% # int32.parse (databinder. eval (container. dataitem, "newsid"). tostring () %> '> </a>

Sometimes there are such prompts .....

2. Sometimes vs2003 automatically adds some code for HTML (for example, adding a table to the outer layer) -- I just can't reproduce the problem.
