Hi there,
I have a Master page, which has a ContentPlaceHolder for the main content of the web pages to go in. I created a webpage from the Master and between the main content tags I put a PlaceHolder control, so that I can add controls via C#. Here is the ASP code below:
<asp:Content ID="Content2" ContentPlaceHolderID="cphMainContent" Runat="Server">
<asp:PlaceHolder ID="PlaceHolderForm" runat="server"></asp:PlaceHolder>
</asp:Content>
The problem is when I try and access the PlaceHolder in my c# code it results in a null object. I was able to access the PlaceHolder fine until I put it in the Master page.
Does anyone know what I'm missing? How would I go about accessing the PlaceHolder inside a ContentPlaceHolder?
Thanks,
Mel

There is your answer. You have to access it through the master page or via the masterpage property.

Hi Mark,
Thanks for the reply.
I've tried accessing "Contact2" and "cphMainContent", which are the Content ID and ContentPlaceHolderID in the related aspx.cs file, but I recieve the error message:
The name 'cphMainContent' does not exist in the current context
How would I go about accessing the PlaceHolder though the Master page?
Thanks,
Mel

This happened because you are loading controls inside the
placeholder at runtime
So it may find placeholder null until you load any control inside it.
However, not sure about it.

Hi All,
I am generating HTML kind of file through code behind. using the following code.
<code>
sb is a string builder
sb.Append("<table border ='0'>");
sb.Append("<tr>");
sb.Append("<td>");
sb.Append("Org Name :");
sb.Append("</td>");
sb.Append("<td>");
sb.Append(Session["orgName"].ToString());
sb.Append("</td>");
sb.Append("</tr>");
sb.Append("<tr>");
sb.Append("<td>");
sb.Append("Start Date :");
sb.Append("</td>");
sb.Append("<td>");
sb.Append(Session["startDate"].ToString());
sb.Append("</td>");
sb.Append("</tr>");
sb.Append("<tr>");
sb.Append("<td>");
sb.Append("End Date :");
sb.Append("</td>");
sb.Append("<td>");
sb.Append(Session["toDate"].ToString());
sb.Append("</td>");
sb.Append("</tr>");
sb.Append("</table>");
sb.Append("<table border ='1'>");
sb.Append("<tr width ='100%'>");
sb.Append("<td width ='15%'>");
sb.Append("SN");
sb.Append("</td>");
sb.Append("<td width ='15%'>");
sb.Append("Patient Id");
sb.Append("</td>");
sb.Append("<td width ='15%'>");
sb.Append("Requested Time");
sb.Append("</td>");
sb.Append("<td width ='15%'>");
sb.Append("Completed Time");
sb.Append("</td>");
sb.Append("<td width ='15%'>");
sb.Append("Study Type");
sb.Append("</td>");
sb.Append("<td width ='15%'>");
sb.Append("Amount");
sb.Append("</td>");
sb.Append("<td width ='15%'>");
sb.Append("Applied Plan");
sb.Append("</td>");
sb.Append("</tr>");
sb.Append("</table>");
below this one accept button will come
<asp:Button ID ="btnAccept" Text ="Accept" runat ="server" onclick="btnAccept_Click" />
but when i am writing this using Response.write(sb.tostring()); to the page
Data is coming is in proper format but the button is coming above html data how to fix this.
</code>
thanks and regards,
Amit Patel

So why are you generating the table like this but using a server control for the button? You can use a DataList or Reperator or DataGrid.

Response.Write executes after the Page Render, that is your button is already rendered in the UI. So, the table will be placed below the Button only. Place a Label or Literal above the Button and set the Text to the sb.ToString().

while displaying star should be highlighted as per average rating, I mean to say that last star might be highlighted 1/2 or 3/4 or ... as per average rating.

Hi,
I am saving pdf file into database reading from memroystream and it is saving properly, but when i try to retreive it it is throwing an error message "ile is damaged and could not be repaired".
I am using itextsharp to generate the PDF, as this is urgent appreciate help.
Thanks in advance.

Hi,
without viewing at your code, it is difficult to decide where the problem is. I'm doing the same
thing with itextsharp and a mysql db in some project. Here is how i basically do it:
Document myDocument = new Document(PageSize.A4);
MemoryStream mstream = new MemoryStream();
PdfWriter.GetInstance(myDocument, mstream );
myDocument.Open();
myDocument.Close();
byte[] fileData = mstream.GetBuffer();
As you're posting this in the asp.net forum, i suppose you want to write this pdf to your reponse stream? (or to file?!)
This is how i write it to response-stream in page-load of a download page
(you have to replace mimeType, fileName, fileSize and fileData by your own variables/strings - with
fileData being the byte[] and filesize the length of that byte[]):
Response.ClearHeaders();
Response.ClearContent();
Response.ContentType = mimeType;
Response.AppendHeader("content-disposition", "attachment; filename=" +
HttpUtility.UrlEncode(fileName, System.Text.Encoding.UTF8));
Response.AppendHeader("content-length", fileSize.ToString());
Response.BinaryWrite(fileData);
Response.End();
Hope this helps. If you've problems writing/reading this data from/to a file, let me know.

I have an ASP.NET 1.1 web application that I'm required to migrate from an IIS 6 environment (Windows Server 2003) to an IIS 7 environment (Windows Server 2008).
I'm experiencing problems with the DHTML menus. In IIS 6 they display the text and the link whereas in IIS 7 it only displays the text, not the link.
Is there a patch that I need to install on Windows Server 2008 to rectify this problem? What am I missing?
The menus display when I view the site in Mozilla (however, the menus don't work 100%), but not IE8
Has anyone else experienced this problem?
I am most confuzzled!!

A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.
So Is that problem in my code or is this the problem from the server. How to fix this ?

At what point can you determine when a web service connection has failed? As near as I can tell, you actually have to try calling a method in the service. Is that correct?

ya that's right
you need to call method to confirm it is getting connected..
For asp.net when you bind service reference
it will tell you by intellisense (at the time of
creating object or calling static method)
that whether you are connected to web service or not.

Hi people,
I want to track what IP's/MAC addresses connect to my web application - but I am having troubles getting the IP of the connecting client.
Every variable or method I try - I seem to end up getting the IP of the server or of the internet provider of the client computer!
Has anyone come across this problem before and come up with a definite solution? I have tried many alternatives that I found via google - but none seem to work 
Any help would be MUCH appreciated!
Thanks in advance.
