Gmail is not a hosting environment, it's an email platform. You need a hosting provider that supports ASP.

Where is the difference between inheriting inline and code-behind

Two test pages.

Test 1: Test1.aspx

<%@ Page Language="VB" AutoEventWireup="false" CodeFile="Test1.aspx.vb" Inherits="Test1" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 
Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
    <title>Untitled Page</title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
    <p>Test 1 - With codebehind.</p>
   
    <p><asp:Literal runat="server" ID="Output" /></p>
    </div>
    </form>
</body>
</html>

Test1.aspx.vb

Partial Class Test1
    Inherits MyCompany.Web.BasePage

    Protected Sub Page_PreRender(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.PreRender
        Output.Text = MyUser.UserName
    End Sub
End Class

----------------------

Test 2: Test2.aspx

<%@ Page Language="VB" Inherits="MyCompany.Web.BasePage" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 
Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<script runat="server">

    Protected Sub Page_PreRender(ByVal sender As Object, ByVal e As System.EventArgs)
        Output.Text = MyUser.UserName
    End Sub
</script>

<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
    <title>Untitled Page</title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
    <p>Test 2 - With inline.</p>
   
    <p><asp:Literal runat="server" ID="Output" /></p>
    </div>
    </form>
</body>
</html>

----------------------

Both pages inherit from a custom class, MyCompany.Web.BasePage, which itself is based on System.Web.UI.Page. The property MyUser is defined in BasePage and contains data about the user accessing the page.

Both pages work just fine when accessed. The difference is when editing the pages: with Test1, MyUser shows up in IntelliSense, I can access the object's properties and everything works exactly as I would expect. With Test2, the use of MyUser is flagged as a "not declared" error, and IntelliSense does not detect any properties on the object.

What is so frustrating is that on my previous development machine, Test2 worked as desired in the IDE. It is only now, after my primary machine had to be replaced (damned hard drive) that this problem has cropped up. Replacing inline code with codebehind is not feasable, as there are hundreds of pages that would have to be rewritten, not to mention overhead from doubling the number of files.

I have no idea why the two different coding styles should suddenly be acting differently. Is there an option checkbox that needs to be marked? Please, help me out!

IMO you should be using inline script anyway. It is a better design and implementation to separate the presentation from the logic.

inheriting - is used when page run on site i.e run time used to acces class file attached with the page.
code-behind - its used desing time its Visual studio attribute its used only at designe time i.e when page desinged not at runtime

How to get handle to webpart in WebPartZone?

Hi

I have a class which is derived from WebPartZone class. As follows.

LeanWebPartZone : Microsoft.Web.Preview.UI.Controls.WebParts.WebPartZone

In this class, I want to set the helpVerb for providing unique helpPage URL for that webpart. Now, on one webpage I have multiple webparts and each webpart might have different helpPage URL. So, my problem is that, at any given time in LeanWebPartZone class, how do I know for which WebPart I am setting the HelpVerb?

Please advise. Thanks

How can I display an image onclick after displaying all images in a folder

Hi everyone,
I'm trying to create a photo-gallery (on an asp.net c# page) that displays all images in a folder and then when an image is clicked it is displayed in a certain place on the page,
the problem is, since I'm displaying all images in a folder I don't have access to the details of the specific image clicked..

this is what I've got so far:

<asp:DataList ID="DataList1" runat="server" RepeatColumns="4" CellPadding="5">
        <ItemTemplate>           
             <asp:Image Width="100" ID="Image1"  ImageUrl='<%# Bind("Name", "~/images/Content/conf2010Photos/{0}") %>' runat="server" />
                   
                    <asp:HyperLink Target="_New" ID="HyperLink1" Text='<%# Bind("Name") %>' NavigateUrl='<%# Bind("Name", "~/images/Content/conf2010Photos/{0}") %>' runat="server"/>          
          </ItemTemplate>
                    <ItemStyle BorderColor="Silver" BorderStyle="Dotted" BorderWidth="1px" HorizontalAlign="Center"
                        VerticalAlign="Bottom" />                       
    </asp:DataList>

I don't really want to use the HyperLink, just to get the image itself clicked, also shouldn't it work on the client side and not go to the server on each click? Confused | :confused:

How could this be done?
Confused | :confused:

many thanks in advance!!

Problem saving Panel Scroll Position on Post Back

10-Mar-10 9:46

Hi
I have a user control, which contains 3 panels, which of course lose their scroll positions on post back of the page.

From my own investigation, I know I need to apply some javascript through the onload method of the body tag, and I want to use hidden fields to save the scrollbar positions. However, I am already using this method on a different user control for a different purpose.

Therefore, I have a few questions, which I need help with:

1) How do I pass in the names of the 3 panels on postback?
2) Get scroll positions of those 3 panels, save it the hidden fields, get it back and apply back to the scroll bars?
3) Apply another javascript function to onload method of the body tag in addition to the one that is already there?

Can anyone help?

If it is only scroll position you are interested in, try putting

MaintainScrollPositionOnPostback="true"

in your @Page directive.

disabling an list item not working in Firefox

Hi..

My .aspx page has an unordered list. I need to disable few items (< li >). Here are the two approaches that I tried. Both working in IE. None works in Firefox. Please help!

Apporach 1:
============
The
runs at server and the < li >s are dynamically created in the code behind. I declare a variable li as htmlGenericControl and assign the required attributes and add this li to the list. Before adding the li to the list, I used

li.disabled = true;

Approach 2:
===============
In javascript onpageload,
document.getElementById("li1").disabled = true;

both are not working in FF. please help.

Kit.

hello guyz appreciate all your effort at codeproject. please take a look at my new website.

but i got the error bellow:

Runtime Error
Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.

Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".



<configuration>
<system.web>
<customErrors mode="Off"/>
</system.web>
</configuration>

Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's <customErrors> configuration tag to point to a custom error page URL.



<configuration>
<system.web>
<customErrors mode="RemoteOnly" defaultRedirect="mycustompage.htm"/>
</system.web>

Try this

<customErrors mode="Off" />

<customErrors defaultRedirect="ErrorPage.aspx" mode="On">   
    <error statusCode="500" redirect="servererror.aspx" />

Home screen design for a website

Hi,

I have an web based application. The content for the Home page has been currently mentioned in the HTML code for the Home page using <table>, <tr> and <td> tags. To change the content anytime in future, it needs to be changed in the HTML code. Frown | :(

Is there a way that we can pick up the content from some external place and get it reflected through the website. This ways, any change if required can be made at the external location without referring to the application's code.

Please advise if there is any solution for it.

Thanks.

You can install one FireFox Addin "YSlow" to have a quick look. Also check Code of login, that database call or other stuff may create performance issue.

Are you storing huge data in session or viewstate once user logs in? You can also check sql profiler if there is any database related bottlenecks.
