Question

1.00/5 (1 vote)

See more:

I have created 3 user controls in three difference directories(Comment,Comment1,Comment2) like
Comment.ascx
Comment1.ascx
Comment2.ascx

Reference those as per give below:

Comment.ascx > Comment1.ascx
Comment1.ascx > Comment2.ascx
Comment2.ascx > Comment.ascx

And getting error like:

Circular file references are not allowed.

As per some of forum I have set

batch="false"

in web config file but still I am getting error.
Is there any solution for that ?

Solution 1

The problem with circular references is that the compiler can not decide which component compile first...
So the only option is to remove such circular dependencies by re-design your application...

I have referenced first user control in aspx page.
Can you let me know which dependencies I have to remove ? or is ther any other solution for that without re-design application ?

Kornfeld Eliyahu Peter 30-Mar-15 8:40am

The question you have to ask is why did you set up those references at the first place...
That will give you the answer of which remove...
I can not tell you an exact answer as I do not know what is your goal, so you have to see by yourself...
And advice: remove all the references between the controls and see if it works...Add only the missing references...

I want to display data hierarchy using three or two user control.

Kornfeld Eliyahu Peter 30-Mar-15 8:52am

It does not mean that you have to have references between the controls you use to display the data. It even not necessary you have different control for every hierarchy - see tree view control that uses the very same control to display endless levels of hierarchical data...

Jaimin H. Soni 30-Mar-15 8:51am

Or I want to reuse of one user control in same page. is it possible ?

Kornfeld Eliyahu Peter 30-Mar-15 8:54am

Of course it is possible, you can put as much instances of the same control as you want! But! do not put too much, it will be a performance problem...

Jaimin H. Soni 30-Mar-15 8:56am

See I am using three level data hierarchy and on third level I want to repeat last level. Example is here like our conversions.

Kornfeld Eliyahu Peter 30-Mar-15 8:59am

Not too clear...
If you see our conversation tree, you will notice that the levels are exactly the same...the only difference is the parent-child relation...

Jaimin H. Soni 30-Mar-15 9:00am

yes but on 3rd level i want stop that hierarchy and continue that level in same manner as per level second to third

Jaimin H. Soni 30-Mar-15 9:03am

level 1
-- level 2
---- level 3
---- level 4(user control 1)
---- level 5(user control 2)
---- level 6(user control 3)
---- level 7(user control ?)
;
;
---- level n (user control ?)

? = which user control ?

Kornfeld Eliyahu Peter 30-Mar-15 9:06am

Why should you use different user control for different levels? Use 'user control 1' for all!!!

Jaimin H. Soni 30-Mar-15 9:08am

yes, I can but we have no idea how much level there.
i Just want to resuse user control on aspx page

Solution 2

1. As I know is not possible to have circular references.

2. The solution is to redesign you controls to avoid this circular references.

You can do this using recursive code. The actual solution will change depending on what your data looks like and how you access it, but this is the gist. All files are in the root of the site.

CommentObject.cs

C#

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace MyNamespace
{
    public class CommentObject
    {
        public int ID { get; set; }
        public int ParentID { get; set; }
        public string Author { get; set; }
        public string Body { get; set; }
        public List<CommentObject> Replies { get; set; }
    }
}

Comment.ascx

XML

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="Comment.ascx.cs" Inherits="MyNamespace.Comment" %>
<div style="border: 1px dashed #aaaaaa; margin-left:30px;">
    <h2><asp:Literal ID="LiteralAuthor" runat="server" /></h2>

    <div><asp:Literal ID="LiteralBody" runat="server" /></div>

    <asp:PlaceHolder ID="PlaceReplies" runat="server" />
</div>

Comment.ascx.cs

C#

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

namespace MyNamespace
{
    public partial class Comment : System.Web.UI.UserControl
    {
        public CommentObject CommentObject { get; set; }

        protected void Page_Load(object sender, EventArgs e)
        {
            LiteralAuthor.Text = this.CommentObject.Author;
            LiteralBody.Text = this.CommentObject.Body;
        }
    }
}

TestPage.aspx

XML

<form id="form1" runat="server">

<asp:PlaceHolder ID="PlaceComments" runat="server" />

</form>

TestPage.aspx.cs

C#

protected void Page_Load(object sender, EventArgs e)
{
    // build up a tree of comments
    // how you do this depends on your data structure, you might
    // even want to load data on the fly in the ShowComments method instead
    List<CommentObject> comments = new List<CommentObject>();

    comments.Add(new CommentObject { ID = 1, Author = "Author A", Body = "Comment 1" });
    comments.Add(new CommentObject { ID = 2, Author = "Author B", Body = "Comment 2" });
    comments.Add(new CommentObject { ID = 3, Author = "Author C", Body = "Comment 3" });
    comments.Add(new CommentObject { ID = 4, Author = "Author D", Body = "Comment 4" });

    // add replies to comment 2
    CommentObject comment = comments.Single(c => c.ID == 2);
    comment.Replies = new List<CommentObject>();
    comment.Replies.Add(new CommentObject { ID = 5, Author = "Author A", Body = "Comment 5" });
    comment.Replies.Add(new CommentObject { ID = 6, Author = "Author C", Body = "Comment 6" });
    comment.Replies.Add(new CommentObject { ID = 7, Author = "Author D", Body = "Comment 7" });

    // add replies to comment 6
    comment = comment.Replies.Single(c => c.ID == 6);
    comment.Replies = new List<CommentObject>();
    comment.Replies.Add(new CommentObject { ID = 8, Author = "Author A", Body = "Comment 8" });
    comment.Replies.Add(new CommentObject { ID = 9, Author = "Author F", Body = "Comment 9" });

    ShowComments(PlaceComments, comments);
}

private void ShowComments(PlaceHolder placeHolder, List<CommentObject> comments)
{
    foreach(CommentObject comment in comments)
    {
        Comment ctlComment = (Comment) LoadControl("~/Comment.ascx");
        ctlComment.CommentObject = comment;

        placeHolder.Controls.Add(ctlComment);

        if (comment.Replies != null && comment.Replies.Any())
        {
            ShowComments((PlaceHolder)ctlComment.FindControl("PlaceReplies"), comment.Replies);
        }
    }
