I have a checkbox that I want to bind to a subclass. The DataSource uses the ParentClass as the business object. Is it possible? Something like:
<asp:CheckBox ID="cb" Text="Test" Checked='<%# Bind("ChildClass.Test") %>' />
public class ParentClass {
private ChildClass _ChildClass; [code]...
I have a subclass Calendar in a cs file. The file is as follows, and I put it in directory named "Test/DataCalendar.cs" .

I would like to subclass an ASP.NET control, like UpdatePanel, and use the subclass in my web site. I know if I move the code to a separate assembly I would be able to reference the assembly from within Register phrase but I wonder if there is a way to keep all the code inside the website.
View 1 RepliesI'm building form validation controls for our C# ASP application. The bulk of the work is handled by a BaseValidator control (subclassing System.Web.UI.UserControl), which also has the markup for the validation output. This is then extended by subcontrols like PasswordValidator, that provides the Validate method and any extra fields needed by that validator control.
(The end goal is to have controls like <uc1:PasswordValidator ControlId="txtPassword" /> which we can plop into any form with minimum duplication.)
However, PasswordValidator.ascx.cs cannot access the form elements defined in BaseValidator.ascx; the only way I've found to do so is to duplicate the markup in each subcontrol's *.ascx file. How can I extend BaseValidator.ascx.cs and access BaseValidator.ascx's markup in the subclass?
Calling aContext.Response.Redirect(...) from an ActionResult subclass' ExecuteResult method results in an HTTP GET being sent to the specified URL.
Does someone know how to get the redirect to send an HTTP POST instead? This is necessary for passing control to PayPal's payment page.

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 am using AJAX ComboBox control (or I can use simple ASP.NET DropDown Control it does not matter) in my form. What I do is, I bind combo box control to my database and retrieve client names:
[Code]....
But here is the problem. I want First and Last names to go into separate TextBox controls (txtFirstName and txtLastName). Now it inserts Last Name and Firts Name in txtLastName control. At the same time I would really like to keep LastName + FirstName together in Combo Box.
In my application, user will enter some meeting dates in one page. In the details page, they need to see those dates to make a selection for one file number. I want to show a calendar in the details page whice will show the dates already entered. To do that I need to bind the calendar to a datasource to get the information from the database.
View 8 RepliesIt's easy to bind a data source to something like a gridview or repeater, but how would I do it with a label? Heres the sql connection that I want to modify. By the way, I don't need 2 way binding.
public void Sql_Connection(string queryString)
{
SqlConnection conn = new SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings["RBConnectionString"].ConnectionString);
SqlCommand cmd = new SqlCommand(queryString, conn);
conn.Open();
cmd.ExecuteNonQuery();
conn.Close();

The query I'm using:

I have a list that I need to bind to a List I get from an API. The list looks like this:
struct DataItem { int level; string name; Guid key };
List<DataItem> myList = API.GetList();
ListView1.DataSource = myList;
ListView1.DataBind();
All this works fine for display. However, the table must edit the level value. I am unsure how to make that happen. I have tried event handlers on the listView, but they are never called. I have tried a text box for the level field (with both Bind and Eval) and an event handler OnTextChanged, but the event handler is never called. (I have tried with various combiniations of AutoPostBack and ViewState enabled.)
How can I programatically edit this data structure?

I have a FormView and I want to set a default value from the database. I can't get it to bind to the value in the database. My FormView looks like this:
[code]....
i will use advanced control like gridview or schedule , and the data that is supposed to be bound to this control is : data from set of tables in my database.not a single table.
what is the best form for this data?
what i thought about at first is:
stored procedure ,contains my logic (and i wanna to ask here about what is the best performance also)use temporary table or joins or ... etc.
what are the possible solutions and more performance rather than stored procedure( as this is a web application many users will use it).

View 1 Replieshow to bind the data to custom control.
ex. i had create a custom control that consist of a TextBox and a Button. how do i tell the aspx to bind the data to the TextBox in custom control like in usual aspx
<asp:TextBox ID="AcNoTextBox" runat="server" Text='<%# Bind("AcNo") %>' />
I am databinding a dropdown list in a wizard step (as long as not the first step). In the Page_Load event, I put the databinding in if (!IsPostBack) block - There is no binding happening, I guess because the system treat the next button click on the previous wizard step triggering a postback.
