How To Order List By String Value
Sep 7, 2010I need to order a list of items, by a string value...
e.g. 635, 955, 5820, 1010 should appear as 635,955,1010,5820, however it shows up as 1010, 5820, 635, 955 because it's a string and not an integer.
I cannot convert to integer, it must eb a string value. how this can be done simply using a string value?
How To Order A TimeZone List In C#
Feb 17, 2010I have an ASP.NET web application that requires users to select their appropriate time zone so that it can correctly show local times for events.
In creating a simple approach for selecting the time zone, I started by just using the values from TimeZoneInfo.GetSystemTimeZones(), and showing that list.
The only problem with this is that since our application is primarily targeted at the United States, I'd like to show those entries first, basically starting with Eastern Time and working backwards (West) until I reach Atlantic time.
Architecture :: Object Life Cycle - What Is The Order Of Events?
Jan 13, 2010I'm trying to better understand the life cycle of an object in the .Net framework. My companies Intranet has some custom classes that were written by a vendor that I'm trying to make some modifications to. Specifically I want to set some variables & hashtables to null when use of the object is done. For now I have this in the dispose event.
Is there any info you can point to that would be good reading on the life cycle of an object in the .Net framework? I.e. what order do the events fire in? OnInit, Initialize, finalize Dispose, etc. I have the ASP.net page lifecycle but I'm not looking for that.
Sort List By Specific Order
Mar 17, 2010If I have a specific order that I want to sort my List by, how do I do that? For instance, I have a list of items (coming from a database), with ID's ... and they come in order, i.e 1, 2, 3, 4. After receiving this list, I'd like to reorder the list above based on a specific order, e.g. 2, 4, 1, 3. How do I do this without complicate it too much?
View 11 RepliesC# - Order A List / No Other Fields Associated With A Category?
Oct 26, 2010I have a function in sitefinity that returns a list of categories.
//return list of categories
private IList<ICategory> GetCategoryDataSource() {
var cntManager = new ContentManager(CaseStudyManager.DefaultContentProvider);
IList allCategories = cntManager.GetCategories();
List<ICategory> filteredList = new List<ICategory>();
foreach (ICategory category in allCategories) {
filteredList.Add(category);
}
return filteredList;
}
What I want to know is how to sort this list.
Categories in Sitefinity are as far as i can tell just a string, there are no other fields associated with a category. Therefore I have nothing to sort the categories on, other than appending each category with a number, like:
1 - Legal
2 - Financial
3 - Property
When these categories are displayed on the website I can then at least trim the parts i need.

View 1 RepliesCorrect The Sort Order Of Sql Dropdown List?
Jan 5, 2010I am trying to correct the sort order of my ASP.NET drop down list.
The problem I have is that I need to select a distinct Serial number and have these numbers organised by DateTime Desc.
However I cannot ORDER BY DateTime if using DISTINCT without selecting the DateTime field in my query.
However if I select DateTime this selects every data value associated with a single Serial number and results in duplications.
The purpose of my page is to display data for ALL Serials, or data associated to one serial. When a new cycle begins (because it is a new production run) the Serial reverts to 1. So I cannot simply organise by serial number either.
When I use the following SQL statement the list box is in the order I require but after a period of time (usually a few hours) the order changes and appears to have no organised structure.

View 1 RepliesC# - Leaving A BinaryReader Object Un-disposed In Order To Keep Request.InputStream Alive?
Feb 1, 2011I have a couple methods to handle the saving of an image using Request.InputStream. I have two extensions that share the HttpContext. In one of my methods, I'm using a BinaryReader to read in the contents and do the processing. However, naturally, when disposing the BinaryReader, it closes off the InputStream property on Request. My SECOND method uses the same input stream to create a thumbnail.
Bascially, I need a way to keep the Request.InputStream property alive after disposing the reader in the first method. Is this possible? Here are my two methods. SaveImageStream() is called first, then GenerateThumbnail().

Web Forms :: Capture List Box Order After Javascript Change
May 13, 2010I have a list box with 2 buttons (up and down) to determine the sort order. To move the items in the list box up or down I am using Javascript. I have a save button which is used to save the new order. However, I have an issue, in that when I have rearranged the order and press save, the order from the code behind is the same as the original order. My list box is:
<asp:ListBox ID="lstSortOrder" CssClass="uiControl" Height="200px" Width="700px" runat="server"></asp:ListBox>
My code behind to save the new sort order is:

View 1 RepliesC# - Order A List Of Entities Based On A Field From A Separate Entity With A Relationship
Mar 6, 2011I'm using Entity Framework for my object-relational mapping, and jqGrid for my grid.
I have an Employee entity, that contains a ContactID field. I have a Contact entity that contains fields FirstName and LastName.
I want to display a list of Employees in a grid, and give the user the ability to sort by FirstName and LastName.
Here's what I have right now:
public JsonResult GridData(string sidx, string sord, int page, int rows)
{
var pageIndex = Convert.ToInt32(page) - 1;
var pageSize = rows;
var totalRecords = GetAllEmployees().Count();
var totalPages = (int)Math.Ceiling(totalRecords / (float)pageSize);
IQueryable<Employee> employees = GetAllEmployees().
OrderBy(sidx + " " + sord).
Skip(pageIndex * pageSize).
Take(pageSize).ToArray();
}
As you can see, this only gives me the ability to sort by fields in the Employee entity, so I can't sort by FirstName and LastName.
How can I modify this to accomplish that?
Forms Data Controls :: Order Of The Items In A DropDown List Inside GridView
Sep 22, 2010I have a DropDownList inside the EditTemplateItem (if the user clicks edit) in a GridView.The DropDownList receives all available rows from the database. My problem is,if the user clicks Edit in the GridView to edit a row and opens the DropDownList Box the original item is not selected but the first one.That means the items are sorted. Have someone an idea how I can solve this issue that the right item / the original is selected if I change to edit mode of the grid view?

Access :: UpdateParameters - Form Order - UpdateCommand Order?
Apr 24, 2010From my testing, it appears that the order of parameters for the UpdateParameters must match both the order of the bound fields on the form (asp:Formview), and the order of the parameters in the UpdateCommand. Is that correct? If so, why do the parameters have names if all that matters is the order? I tried both asp:ControlParameter and asp:Parameter. Maybe the more relevant question is why aren't the names used instead of the order, particularly for the form order?
So, given I display the Identity field (CID), and need that for the update, I cannot get the update to work without including it in the UpdateCommand. Of course, since it is an autonumber field in Access, I cannot actually set it. So, I had to add another field to the db (lngUpdateCID) that I could set. That can't be how it has to be done, but I could not figure out another way to do this.
The relevant code is below:
