Re: Return only spfields that are filterable

2011-11-03 Thread Salman Ahmad 
Hi Paul, 

Here is a sample you can start with. 

using(SPSite site = new SPSite(http://localhost;))
using (SPWeb web = site.OpenWeb())
{
ListSPField fieldsList = new ListSPField();

SPFieldCollection fieldsCollection = web.Fields;

foreach (SPField field in fieldsCollection)
{
Console.WriteLine(field.Title);
fieldsList.Add(field);
}
}

Use fieldsList to populate your DropDownList.

You can also get Fields Collection for your lists in the same way, 

Cheers,
Salman

Subject: Return only spfields that are filterable

Can anyone provide an example of how I can use the SPField.Filterable property 
to return all fields where this is true?

I want to use this to dynamically populate a DropDownList control.

my bad, I missed actual condition, 

foreach (SPField field in fieldsCollection) {   
  if (field.Filterable) {   
  Console.WriteLine(field.Title); 
fieldsList.Add(field); } }
Cheers,

:) Great. That's exactly what I was after. Thank you!
One more question surrounding using. Whenever I use using I get web part 
errors saying that the data has already been disposed. This usually occurs when 
trying to edit the web part properties.
As a result, I now just do the folowing but am unsure as to whether this needs 
to be disposed at some point?
try
{
oList = SPContext.Current.Web.Lists[oListName];

You will not need to dispose SPContext,

As a general rule if we create an object only then we dispose it..

 Incidentally, I am using a DropDownList control and the following worked a
 treat. Never ceases to amaze me just how simple these things are when you
 know how.
