Inspite of people telling you repeatedly that use 'PRE' tags to format code such that your post is readable, you keep posting code without them.

It's really difficult for people to go through the code without it. You can still edit your question. Use 'code block' present in the formatting options. Place your code in between those code blocks pre tag.

The simple way is that you should replace your code [AddControls(Page.Controls, controlList);] in method ListControlCollections by the code [AddControls(Page.Master.FindControl("ContentPlaceHolder1").Controls, controlList);]

In above code I assume that your ContentPlaceHolder ID is "ContentPlaceHolder1". The idea of this code is that you first search your ContentPlaceHolder then only search all controls in the searched ContentPlaceHolder control.

Make it better.

The Problem is Have more than one contentplaceholder so ,I will not search for a specific
One but all I need is to search only in the contentplaceholders controls without getting any controls from master page
i tried your idea but it do work only with one contentplaceholder.
and the out put is:
==============================
Irange-------------------------> inside master page
LoginStatus1------------------------->inside master page
ContentPlaceHolder1------------------>Contain the following
Panel1
TextBox1
Label1
Button1
ImageButton1
LinkButton1
DropDownList1
HyperLink1
ListBox1
txt_startDate
CheckBox1
Calendar1
gv_List
Button2
ContentPlaceHolder2--------------------->contain the following
Eslam
EslamTXT
Total Controls:20
==============================
the idea that i want it loop only through the contentplaceholders
Thanks.

Ok, I see.
So I think first we should implement a method that list all ContentPlaceHolder control such as GetAllContentPlaceHolders.
Then we will loop all get controls and search all inside controls.
The GetAllContentPlaceHolders could be implemented as following code:

private IEnumerable<Control> GetAllContentPlaceHolders()
{
    Queue<Control> controls = new Queue<Control>();
    foreach (Control c in Page.Controls)
    {
        controls.Enqueue(c);
    }
    while (controls.Count > 0)
    {
        Control c = controls.Dequeue();
        if (c is ContentPlaceHolder)
        {
            yield return c;
        }
        foreach (Control ic in c.Controls)
        {
            controls.Enqueue(ic);
        }
    }
}

After that in your orginal ListControlCollections method, you should replace AddControls(Page.Controls, controlList); by

foreach (Control c in GetAllContentPlaceHolders())
{
    AddControls(c.Controls, controlList);
}

Hope it helps

Best regards,
HauLD

Hi all,

I need yours openions in following scenario

I have a web application where we allow to import data from xml file and the xml file could be larger like 10 to 20 MB containng more than 100000 record.

For this thing we have increased the maxrequestlength upto 20MB as well as executiontimeout upto 1 hr.

Can anybody confirm it is good to allow such processing via web application? if no then plese suggest me some alternative way to handle such case.

Thanks
Rohit

You could allow your clients to FTP the files to you and then process them with a dedicated application rather than through the web application?

Thanks dear for your kind suggestion. I will suggest to my client to do so but I would welcome the another approach for such case.

Thanks dear but our problem is not related to loading of file but processing the file content which contains looping for data validation for each tags and number of tags could be more than lacs
