Re: The header and footer contents in master page are refreshing - Need help

1-Dec-11 12:29

The master pages solves an old issue with classic asp, php, and just plain html in which developers wanted to create a consistent header and footer. So before in the old days, you had to sort of slip your header and footer file into your content file, or vice versus, I don't remember which.

if you place linkbuttons on your master page, when you click them they will generate a postback like they are suppose to. They are not refreshing, but are sending the form back to the server for processing.

Now with just plain html, you can get rid of the form tag, and the page will not postback, because there is no form data. But ASP.Net requires a form tag on all pages.

So if you want to confine the postback to just the content, wrap the content in an update panel, and make a trigger for each button you need to issue a small async postback to the server, in which only the content in the update panel will make the round trip to the server and back.

You can rid of the linkbuttons, for they are not needed, unless you need to calculate something before the action. Use a Hyperlink if you want to send to another page.

XML

<td style="width: auto; text-align: right;">
     <asp:Hyperlink ID="lnHome" runat="server" class="hrefClass">Home</asp:Hyperlink>&nbsp
     <asp:Hyperlink ID="lnLogout" runat="server" class="hrefClass">Logout</asp:Hyperlink>
</td>

<asp:ContentPlaceHolder id="ContentPlaceHolder1" runat="server">
     <asp:updatepanel id="updatePanel_Content1" runat="server">
    <asp:contentTemplate>

    </asp:contentTemplate>
    // add a asyncpostback trigger
     </asp:updatepanel>
</asp:ContentPlaceHolder>

WCF message edit error

Hi,

I used the following code to edit a wcf message using message inspector.

MemoryStream ms = new MemoryStream();
               Encoding encoding = Encoding.UTF8;
               XmlWriterSettings writerSettings = new XmlWriterSettings { Encoding = encoding };
               XmlDictionaryWriter writer = XmlDictionaryWriter.CreateTextWriter(ms); //CreateBinaryWriter(ms);
               message.WriteBodyContents(writer);
               writer.Flush();
               string messageBodyString = encoding.GetString(ms.ToArray());

               // change the message body
               messageBodyString = messageBodyString.Replace("<n1>100</n1>", "<n1>200</n1>");

               ms = new MemoryStream(encoding.GetBytes(messageBodyString));
               XmlReader bodyReader = XmlReader.Create(ms);
               Message originalMessage = message;
               message = Message.CreateMessage(originalMessage.Version, null, bodyReader);
               message.Headers.CopyHeadersFrom(originalMessage);

Actual body of the message was like

<s:Body u:Id="_0">

    <Add xmlns="http://Microsoft.Samples.AdvancedFilters">

      <n1>100</n1>

      <n2>15.99</n2>

    </Add>

  </s:Body>

I wanted to change the value in the

<n1>

tag from 100 to 200. But after executing the method

Message.CreateMessage(originalMessage.Version, null, bodyReader)

, the body is shown like

<s:Body>... stream ...</s:Body>

It is in my opinion that you going about the process backwards.

When working with xml, no matter what the packaging is, wsdl, etc, you have to build the framework needed to write the xml file, edit, update, add, delete elements and child elements first.

Then you need to write the code needed to read and write it to the disk drive.

Now memory streams come into play, with memory stream, you can create a brand new xml file, store it in a memory stream, and transmit it to another server, or just send it to another function without ever touching the disk drive. While in memory, you can stuff it into your xml editor, modify it, store it back in the memory stream, and send it back out.

I use xsd to create a model of my xml, and compile it into a class object using xsd.exe /classes /vb /sample.sml to create sample.vb.

Then I use XMLTextWriter, to load up the sample.vb. The class wires up the xml structure, so an edit is as simple as sample.n1 = 200

Can u give the code??

This is a xsd template. I write them in Liquid Studio, but now I can write them from scratch. This one is very simple. I don't export the xml as a memory stream, but I do hold the entire xml in server memory, and when done, I write it back to the disk drive. The xsd, xml, program code all matches together. This is the fastest xml in asp.net. It is capable of doing 10 transactions per second, and I have 1 complex file with over 20,000 records in it, that can update really fast. This is how you write xml for DHL Express, UPS, Chase Payment Tech, PayPal, and any other web service that requires XML. It may be very difficult to comprehend at first, but I did all the heavy lifting for you.

You can save this as Sale_Messenger.xsd

XML

<?xml version="1.0" encoding="utf-8" ?>
<!--Created with Liquid XML Studio - FREE Community Edition 7.1.6.1440 (http://www.liquid-technologies.com)-->
<xs:schema elementFormDefault="qualified" xmlns:xs="http://www.w3.org/2001/XMLSchema">
  <xs:element name="Sale_Messenger">
    <xs:complexType>
      <xs:sequence>
        <xs:element minOccurs="1" maxOccurs="unbounded" name="Registered_Members">
          <xs:complexType>
            <xs:all>
              <xs:element name="Name" type="xs:string" />
              <xs:element name="EmailAddress" type="xs:string" />
            </xs:all>
          </xs:complexType>
        </xs:element>
      </xs:sequence>
      <xs:attribute name="Version" type="xs:string" />
      <xs:attribute name="CreationDate" type="xs:string" />
    </xs:complexType>
  </xs:element>
</xs:schema>

Now I run the xsd using LS, to confirm it makes a valid xml file.
Sale_Messenger.xml

XML

<?xml version="1.0" encoding="utf-8" ?>
- <!--  Created with Liquid XML Studio - FREE Community Edition 7.1.6.1440 (http://www.liquid-technologies.com)
  -->
- <Notification xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="C:\Sep-WSDLS\TransactionNotifications\TransactionNotifications.xsd" Version="string" CreationDate="string">

  <Name>string</Name>
  <EmailAddress>string</EmailAddress>

  <EmailAddress>string</EmailAddress>
  </Registered_Members>
- <Registered_Members>
  <Name>string</Name>
  <EmailAddress>string</EmailAddress>
  </Registered_Members>
  </Notification>

So I have 2 files, Sales_Messenger.xsd, and Sales_Messenger.xml

I use xsd.exe on the xsd file - xsd.exe /vb /classes Sales_Messenger.xsd to produce a Sales_Messenger.vb class. Now I import the class into my project. You can find xsd.exe in VS 2005, 09, 10. Make the file and copy it into your project, include it.

Then I wrote a new class, to create a new file, update, and delete.

hi friends

i am developing an asp.net project in c#.
In a master page i have a loginstatus control on the click of the control i have written:

protected void LoginStatus_LoggingOut(object sender, LoginCancelEventArgs e)
{
Session["UserId"] = "";
Session.Abandon();
Response.Redirect("../Login.aspx");

}

which redirects to the login page but from that page, if i type an aspx page in the site information tab where we used to type the webaddress it takes me to the page by the person name who just logged out

can anyone help me in this issue.

Hi Gayathri,
Please give
Session.Clear();
Session.Abandon();
Session.RemoveAll();
Respons.Redirect("Test.aspx");

This will clear ur session used.

You can directly use

Hi,
On each menu or sub-menu-item click,the full page ie header,content placeholder and footer are refreshing.Need help.....

Suggest some url.or sample .net website where i can refer the code.

I had tried placing header and footer as seperate user control.But it failed on each menu item click or sub-menu item click.

Using Iframe makes peformance slower.

Thanks
