Forms Data Controls :: Best Practice For Gridview Creation/Maintenance?
Oct 7, 2010
I have been tasked with producing a web application for a new client. What they're looking for requires a Gridview with slave Detailsview within an Update Panel.
I produced this, including the Gridview in markup, as follows:[Code]....
[Code]....
However, although it works, it's been requested that I move most of this to code behind (for easier maintenance), which is causing me a few headaches.
What is the correct option here, since I see many potential methods?
Should I create an instance of the Gridview and Update Panel in markup, then define all events and columns in code behind? Create a new Gridview entirely in code behind and place it within the Update Panel? Create both in code behind?

I think I've created and instantiated my first custom class. I'm pretty darn excited! Been reading up on it, I think I did it right but I'd like someone to double check. I'm trying to collect question ID's and associated answer values from a databound gridview and then insert them into the database.
I have two questions:
-Did I set up and instantiate the new class correctly? (also will need to access the class on other webpages)
-Am I ready for the next step of inserting into the Database with LINQ or is there something else I need to do?

I have a stored procedure (For Eg: sp_GetAvlData) that accepts a number of parameters, 3 of which are TimeFrom, TimeTo (as varchar) and TimeInterval (as int), formulates a Dynamic query and executes itself. So for instance, if I call the proc as follows:
[code]....
dtAvl is the datatable containing the results of my stored procedure.
The next step for me is to make each of the cells (except the cells in the first column) as a Hyperlink so that when clicked upon a cell, it populates 2 textboxes with the selected Timeslot and Name or ID (ID field is not displayed in Gridview). The textboxes are located on the same page but outside of the Gridview control.
The Challenge that I'm facing out here are:
1) As you can see, the field names being generated are not fixed and I have no control over them.
2) Because the field names are not fixed I'm not sure I can implement this using the Templatefields or BoundFields of Gridview.
Is there any way to achieve the Hyperlinking of these cells within the Gridview?

I have what's bound to be a stupid question, so I'll apologize for what I think should be an obvious answer my brain just can't see. My problem is very simple. I have a Repeater control bound to a SqlDataSource. The ItemTemplate in this case is one complicated beast, and rendering can take a loong time if too many records are returned; so I need to maintain tight control over how many records are brought back from the data source.
Is there not some way of either stopping the creation of subsequent RepeaterItems once a certain count has been reached, or cancelling the bind if more than a certain number of records are returned? I know I can grab the record count from the AffectedRows property in the Selected event of the DataSource, but I've encountered a brain-lock on how to stop/inhibit the binding (or RepeaterItem creation beyond x records).
I'm happy with either aborting the binding altogether if the record count is too high (displaying no records), or simply stopping it after X records are returned; at this point, I'm not picky. Either way would work, and it seems I ought to be able to readily figure out either one, but my brain has simply gone into neutral.

I'm trying to build a website for real estate listing. now the data would look like a datagrid. and while clicking on it, it should open under the clicked row the dynamic data related to the specific row. (like an AJAX accordion). this website for example ( ignore the language, couldnt find any better example [URL] Now, i've been told that this works by using "Dynamic Div Creation" which i have no idea how it should work this way. Is it possible to make it work by using an Accordion inside a datagrid? or what?

My understanding of Factory Method Pattern is (Correct me if i am wrong) Factory Method Pattern "Factory Method allow the client to delegates the product creation (Instance Creation) to the subclass". There are two situation in which we can go for creating Factory Method pattern.
(i) When the client is restricted to the product (Instance) creation.
(ii) There are multiple products available.But a decision to be made which product instance need to be returned. If you want to create Abstract Method pattern
You need to have abstract product Concrete Product Factory Method to return the appropriate product.
public enum ORMChoice
{
L2SQL,
EFM,
LS,
Sonic
}
//Abstract Product
public interface IProduct
{
void ProductTaken();
}
//Concrete Product
public class LinqtoSql : IProduct
{
public void ProductTaken()
{
Console.WriteLine("OR Mapping Taken:LinqtoSql");
}
}
//concrete product
public class Subsonic : IProduct
{
public void ProductTaken()
{
Console.WriteLine("OR Mapping Taken:Subsonic");
}
}
//concrete product
public class EntityFramework : IProduct
{
public void ProductTaken()
{
Console.WriteLine("OR Mapping Taken:EntityFramework");
}
}
//concrete product
public class LightSpeed : IProduct
{
public void ProductTaken()
{
Console.WriteLine("OR Mapping Taken :LightSpeed");
}
}
public class Creator
{
//Factory Method
public IProduct ReturnORTool(ORMChoice choice)
{
switch (choice)
{
case ORMChoice.EFM:return new EntityFramework();
break;
case ORMChoice.L2SQL:return new LinqtoSql();
break;
case ORMChoice.LS:return new LightSpeed();
break;
case ORMChoice.Sonic:return new Subsonic();
break;
default: return null;
}
}
}
**Client**
Button_Click()
{
Creator c = new Creator();
IProduct p = c.ReturnORTool(ORMChoice.L2SQL);
p.ProductTaken();
}
Is my understanding of Factory Method is correct?

I was wondering about some best practices for data binding in web forms. For example we have a control:
public partial class MyUserControl : UserControl
{
public override void DataBind()
{[code]...
If we wanted that control to bind its data automatically we would do something like this:
protected void Page_Load(object sender, EventArgs e)
{
if (!this.IsPostBack)[code]...
In the first section of code if we do our data binding before the call to base.DataBind() (#1) then that means that, if for example we databind a ListView, we don't have to call ListView.DataBind() because when we call base.DataBind() on our control it recursively calls DataBind on all child controls. Also, we won't have access to any of the properties of the control that were assigned to it using the data binding code blocks <%# %>
If we do our binding on our controls after base.DataBind() (#2) then this means that DataBind is called on these controls twice. Once when base.DataBind() is called, and the second time when we are forced to call control.DataBind(). I can follow here that I don't know about?
EDIT: Looking at this page:
http://msdn.microsoft.com/en-us/library/w5e5992d.aspx
Use this method to bind data from a source to a server control. This method is commonly used after retrieving a data set through a database query. The method is primarily used by control developers; most controls perform data binding automatically.It appears that best practice is to bind controls data automatically. Databinding is for when we explicitly set a data source.

I have an ASP.NET site that I'm going to have to take down to make some major structural updates to, and I was wondering how I should go about it from the client-side perspective. I have heard of an App_Offline.htm file or something like that, but I've never really gotten that to successfully work. Does anyone know how to do this?
EDIT
My app is running ASP.NET 4.0, for what it is worth.

I had successfully created a functionality where I can dynamically add rows and columns to a asp table by creating/re-creating controls on every page load.
I have 2 buttons - Add rows and Add columns that, basically according to a asp.,net page life cycle, occur in the following order and work perfectly fine.
Page load is fired and controls along with their viewstate are recreated. In Add row button click event - I just create a new table row and add controls to each cell dynamically.
Same thing with Add column, Delete Row and Delete Column button click events.
However, now I added a Dropdown which when its index is changed needs to retrieve values from the database and create controls based on those values and then also bind the Db values.
But it doesn't work correctly since the asp.net page cycle cannot capture the dropdown's selected value in page_load as the page_load fired first and then the selectedindexchanged event is fired later, the controls are not created.
I don't know how to handle this scenario and incorporate it into my existing code.

What I'm looking to do is lock the application so the admin can do maintenance for however long. All i want to do is be able to click a button on a "maintenance" page and it makes it so anyone who attempts to use the system and anyone who is already in the system is redirected to a page, if they try to do anything, that says the site is down for maintenance.
on postback, on redirect, etc. No Access until that button is clicked again to unlock.

I'm currently using the fantastic DorkNozzle 'framework' for building a very basic blog in .NET.My first "self-taught" script is as follows, and is for solely retrieving SQL results.
PHP Code:
<%@ Page Language="C#" MasterPageFile="~/Dorknozzle.master" AutoEventWireup="true" Title="Blog" %>
<%@ Import Namespace = "System.Data.SqlClient" %>
<script runat="server">[code]....
I should change to perhaps improve my coding style, without going down the MVC line just yet?

In asp.net 3.5, what's the best (most convenient) way to redirect users to a page that informs them the "Site is currently undergoing maintenance. check back later."
Originally, someone recomended setting the starting page in IIS, but I don't have access to IIS (hosting company does) so that's not an option. Another person said to go into visual studio, right-click on the desired starting page, and mark it as "Set as start page", but that would involve recompiling & uploading the website EVERY time I want to perform maintenance & then recompile again once I'm done.
Am I able to specify the start page in my web.config file or something along these lines?

A web application works with the database. Once a day, the database should be scanned and alerts should be sent to users. From what I've seen out there, additional project has to be created which will be installed on the server and will work with the same database. Executable created by this project has to be installed in Windows scheduler to be activated once a day.This seems complicated and inefficient: starting additional executable and working on the same database.
