i had made one integer 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.

Best thing is debug your control by putting break points at proper places.
Can't make any conclusion as we don't know what you have coded for the same

I have tried debugging the application by putting breakpoints.
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.

hi,

I have been looking around on different sites and fora, and i have a similar
problem than some people had before...
it is an error to use a section registered as
allowDefinition='MachineToApplication' beyond application level. This error
can be caused by a virtual directory not being configured as an application
in IIS.
this is the solution i've read (almost everywhere)
"You need to create an application or a virtual directory ( with the IIS
Manager ) for the directory in which the code is placed."
Since I have several subfolders in my app, that would mean that I have to
make an application of every single folder?
There has to be another solution, or am I wrong ?
Thanks and Regards

Why do you want to send values in header it should only contain the inforamtion of its body
Any way check the response.addheader methos there check what parameters it takes

HTTP header ? or through URL ?

ya thorugh HTTP header..

Adding values to HTTPHeader on page level is not possible. You need to write a HTTPModule or a class that inherits from HttpApplication. Write your header value adding code in BeginRequest event.

Yes it is. I did it just the other day. Here is the actual code that I used:
Response.AddHeader("Content-Disposition", "attachment; filename=\"" + file.FileName + "\"");

You can only send information from the server to the browser using the HTTP header. It doesn't pass on the information in the next request.

You need to show data's need to be exported on a DataGrid. Say Datagrid1. Set the page response content type to excel. Using HTMLTextWriter to render the grid and write that to response. See the following code
Response.ContentType = "application/vnd.ms-excel";
Response.Charset = "";
this.EnableViewState =false;
System.IO.StringWriter ObjTextWriter= new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter ObjHTMLWriter= new System.Web.UI.HtmlTextWriter(ObjTextWriter);
Datagrid1.RenderControl(ObjHTMLWriter);
Hope this helps
