Commonly .NET applications are developed using 3-Tier(layer) architecture. Most of the Application Logic and Data Access Code resides in seperate components for easy maintainance and Code reusability.
Presentation Layer
This deals with the User Interface of the application. It is responsible for delivery of information to the end user and to the Application.
Business Logic Layer
This Layer Process the Data and Moves the Data Between Presentation and Data Access Layer. This layer physically separates the Presentation Code and Data Access Code. It acts as an interface between these two layers.
Data Access Layer
Since ADO.NET is the Data Access technology under .NET, the ADO.NET code to communicate with the Database is written in this layer.
I made it very precise to give you an Idea what it is. Hope this helps...

Thats simple first thing is that put all controls in page initially by making them hidden then on add new row button call a javscript that will show those controls . Now don't ask for the javascript first try your self
1. Google how to hide the controls. Hint(hide the TR in which your controls are present by making its style.display='none')
2. now write a javscript function that will show this controls
3. Register that javascript in Page load by simply adding (AddNewButtonId.Attributes.Add("OnClick","javascript:FunctionNameWrittentoShowControls();"));
Thanks and Regards

Hi everyone,
I am facing a weird problem in one of my web page. After postback the font size of the controls in the page is changing though no changes in the font are made through code. The default font properties are getting changed after post back.

The page has a tree control, a label control, a textbox and a button.
When the button is clicked a postback occurs and the size of tree control and label control changes from X-small to medium and height of textbox changes from 13px to 2 px.
Thanks,
Srikanth

That sounds strange are you using javscript function hide and show perpose or are you adding new control after post back check your html content i think some tags are not properly closed
Thanks and Regards

thanks for the reply, actually the system are already converted from 1.1 to 2.0 but the MS_POSITIONING attribute reflect an error on HTML code, all i need to know, if the MS_POSITIONING is still supported on 2.0 version of .Net or any attribute that replace the function of MS_POSITIONING
|
|
|
|
|
MS_Positioning is not supported in ASp.Net 2.0 version.

thaks for the reply, what will be the effect of this MS_POSITIONING on the page if the 1.1 version was converted to 2.0
|
|
|
|
|
ASP.NET 1.1 to ASP.NET 2.0 Migration #2
I believe that MS_POSITIONING keyword is deprecated in ASP.NET 2.0.
ASP.NET 1.1
<body MS_POSITIONING="FlowLayout">
ASP.NET 2.0
By default, ASP.NET 2.0 is based on Flow Layout. So just remove the MS_POSITIONING keyword.
<body>
But how about GridLayout?
That is a very good question. Since all the ASP.NET 2.0 by default are based on FlowLayout, how can we change this?
ASP.NET 1.1
<body MS_POSITIONING="GridLayout">
ASP.NET 2.0
You still have to remove the keyword MS_POSITIONING like this:
<body>
But in order for you to use grid layout for absolute positioning of controls, do this:
In your VS 2005 IDE, click on Tools -> Options -> HTML Designer -> CSS Positioning
Then checks the "Change positioning to the following for controls added using the Toolbox, paste or drag and drop", then selects "Absolute Positioned"
OR you can do this:
Say you only want certain control to be absolute and others still based on flow layout. Select a control on the designer and then go to Layout -> Position
Change from Not Set to Absolute
--------
Thnks for posting this question. I too donno the answer. got this from some .net forum

i have made one double type collection editor in web control library project.
the collection gets displayed properly at design time and i am able to add and remove items also but my problem is that value entered at design time does not effect the control at runtime.
Here's the code :
First of all I designed a class for creating a List Collection :
using System;
using System.Collections.Generic;
using System.Text;
using System.Collections;
namespace Funnel
{
public class SectionValue : CollectionBase
{
public double this[int index]
{
get
{
return ((double)List[index]);
}
set
{
List[index] = value;
}
}
public int Add(double value)
{
return (List.Add(value));
}
public int Add(string value)
{
try
{
double c = Convert.ToDouble(value);
return (List.Add(c));
}
catch (Exception)
{
throw new ArgumentException(string.Format(
"Error converting the given string '{0}' to a color",
value), "value");
}
}
public bool Contains(double value)
{
// If value is not of type Color, this will return false.
return (List.Contains(value));
}
public int IndexOf(double value)
{
return (List.IndexOf(value));
}
public void Insert(int index, double value)
{
List.Insert(index, value);
}
public void Remove(double value)
{
List.Remove(value);
}
public SectionValue(double[] sections) : base()
{
foreach (double s in sections)
{
this.Add(s);
}
}
public SectionValue()
: base()
{}
}
}
Then I use object of the class in my control as follows :
protected SectionValue m_SectionValue;
and write property for it as follows :
[Bindable(true)
, Category("Appearance")
, Browsable(true)
, PersistenceMode(PersistenceMode.Attribute)
, DesignerSerializationVisibility(DesignerSerializationVisibility.Content)
]
public SectionValue UserDefinedSection
{
get
{
if (m_SectionValue == null)
m_SectionValue = new SectionValue();
return m_SectionValue;
}
set
{
m_SectionValue = value;
}
}
Now this code is working perfectly regarding displaying the collection editor and add/deleting values from it. Even I am able to  add/delete values from code-behind.
But the values added during design time do not get reflected at run-time. If I assign values to collection from code-behind file then the values get reflected at run-time but not from design-time.
Thanks & Regards,
Ujjaval Modi.

Hi Guys and Gals.
I have a grid view with static data. The last column is a textbox template field. Now what I am trying to do is:
Once the user has filled in a value and move away from this textbox control (say to the next row), I want to validate the value entered into this textbox and then update the value in one of the static fields of the GridView control.
Can anybody give me advise on what will be the most efficient way of doing this please?
Regards,
Elizma
