The server tag is not well formed.

use "Mng.aspx?fileOutIdBook='<%#Eval("fileOuId") %>'&module=DeletFile"

Solution 2

It seems you got a syntax error. All inline expressions must have a whitesapce between opening and the actual content:

ASP.NET

<asp:imagebutton id="ImageButton2" postbackurl="Mng.aspx?fileOutIdBook=<%#[here must have a whitespace]Eval("fileOuId") %>>&module=DeletFile" runat="server" xmlns:asp="#unknown" />

Do one thing, replace your PostBackUrl bythe below one:

HTML

PostBackUrl='<%#"Mng.aspx?fileOutIdBook="+ Eval("fileOuId") %>&module=DeletFile'

OR try

HTML

PostBackUrl='<%#"Mng.aspx?fileOutIdBook="+ Eval("fileOuId")+&module=DeletFile %>'
