Content Of DropDownList Not Sorted
Feb 10, 2010
I'm currently using asp.net dynamic data. I have used the standard procedure and created as it is shown in the videos a new class to have some tables individually designed. But now I'm running into the problem that the content of the drop down list is not sorted. I don't want to sort it on the SQL server. I already had a look into some forums and I found this:
public static void SortDropDownList(DropDownList ddlList)
{
ArrayList arl = null;
if (ddlList.Items.Count > 0)
{
arl = new ArrayList(ddlList.Items.Count);
foreach (ListItem li in ddlList.Items)
{
arl.Add(li);
}
}
arl.Sort(new ListItemComparer());
ddlList.Items.Clear();
for (int i = 0; i < arl.Count; i++)............

Problem: Content Page with Wizard Control with UpdatePanel and Placeholder. Above the UpdatePanel is a DropDownList. I need to display different input controls below the drop-down list when the user changes the selection in the drop-down list. When the user clicks 'Next' on the wizard control, I need to be able to get the data out of those dynamic controls as well.
I know all the dynamic controls have to be created in the OnInit method in order to get the data back from those controls during the postback. However, when the drop-down list's SelectedIndexChanged event is fired, the OnInit method is called... then the PageLoad... and finally the handler for the SelectedIndexChanged event is called. ViewState hasn't been restored until well after the OnInit & PageLoad methods have been called, so there is no way to know what the user chose in the list box at the time OnInit is called... which exactly when I'm required to create the dynamic controls.

I have a gridview control connected to a sqldatasource control. I am allowing the user to sort the columns in the gridview control. The user can click a row and visit another page. When they return I need to set the column sort again. I have seen that I can use the Sorting event to set the sort order of the data when I return to the page in the Sorting event. But before I leave the page where can i get the column it is currently sorted on along with the direction?

I would like to call a method in the ObjectContext which returns EntityCollection and have it sorted the way I want by default. For example, Imagine I have the following Category table/class:
CategoryID (PK)
Name
ParentID (FK_Category) foreign key
pointing to CategoryID itself.
(This table is the base for a tree structure of Categories and SubCategories)
Now, in my data model, the public partial class Category : EntityObject has a property which returns all Categories that have ParentID==CategoryID, in other words, EntityCollection<Category> SubCategories.
Alright, now i want to show in my page all the Categories and SubCategories by using Repeater:
<asp:Repeater ID="rptSubCategories" runat="server">
<ItemTemplate>
<%# Eval("CategoryID") %> - <%# Eval("Name") %>
<asp:Repeater ID="rptSubCategoryCategories" runat="server" DataSource='<%#Eval("SubCategories")) %>'>
<ItemTemplate>
<%# Eval("CategoryID") %> - <%# Eval("Name") %>
</ItemTemplate>
</asp:Repeater>
</ItemTemplate>
</asp:Repeater>
Then in code behind, I set the DataSource:
IList<Category> categoryList = new CategoryProvider().GetAll();
rptSubCategories.DataSource = categoryList;
rptSubCategories.DataBind();
Simply and everything works! Except that, rptSubCategoryCategories doesn't gives sorted Categories by Name. The only way I found to do it, is to change its DataSource from:
DataSource='<%# Eval("SubCategories")) %>'
to:
DataSource='<%# ((EntityCollection<Category>)Eval("SubCategories")).OrderBy(p => p.Name) %>'
but I wish I could do something else to have a default sorting so i don't need to call the OrderBy. Something like Attributes like we do in DynamicData, following the tutorial at [URL] Setting the default sort column of an Entity with DisplayColumnAttribute. Unless somebody tells me it's impossible what I want to do.

I have an ASP.net gridview on a webform where user's can select a row. When they select it, the row is highlighted yellow. The problem is that when I sort the table, it sorts properly but the highlight stays on the same line. The data all moves, but the highlight stays put.

Using ASP.NET 4.0 with C#.
I have a GridView and have sortable columns. When a column is sorted the GridView automatically selects the top row, however the SelectedValue is still representing the row before the column is sorted. The SelectedValue of the GridView only gets changed when a row is selected, but I want that to happen when the GridView is sorted.
For example if I have this in my code:
[Code]....
itemId is populated with the old SelectedValue not the new one after the GridView has been sorted.

I have a list of ids properly stored in a List<>. I now need to Group list and get a count of the number of occurrences sorted descending.
Example:
List<string> aryIDs = new List<string>;
aryIDs.Add("1234");
aryIDs.Add("4321");
aryIDs.Add("3214");
aryIDs.Add("1234");
aryIDs.Add("4321");
aryIDs.Add("1234");
Would Produce:
"1234", 3
"4321", 2
"3214", 1
This would be easy in TSQL, but I would like to avoid the server roundtrip, unnecessary tables, etc. if possible.

I see from google that this is a common problem. I have a SQL server database that contains 26 rows of data. Two columns, the first is PK and an identity column (keys numbered 1 to 26) and the second column is a text field (nchar(10)) containing a letter of the alphabet (A..Z). The letters were inserted randomly to simulate sql being unsorted by default. I have a query that returns all of the data ordered by the letter column ascending. If I execute the query in sql server I get 26 rows orderd A..Z.
I have a gridview that is set up for paging (page size = 15) and sorting. When sorting is disabled, all data is correctly displayed on the gridview, 15 rows on the first page, 11 rows on the second page.
If I enable sorting, I get 15 rows on the first page and 11 rows on the second page, however on closer examination I find two letters missing and two letters duplicated on both pages. If I navigate to page two, then back to page 1 I find that the data is then shown correctly and the missing letters are back.
Has anyone struck this issue? I am thinking that the sort is not being initialized correctly, but am not sure where to look.

I am building a SortedList object for use as the DataSource of a GridView control. The key-value pairs are being built manually with the "key" fields being inserted in already sorted order. The "key" column is invisible with the "value" column the single displayed data item. I set the DataSource property of the gridview to the sortedlist and call the Bind method. The gridview then displays the data in random fashion!

So I have a gridview that is sortable. I also have enabled it to export to excel. The problem is that it exports the original datasource and not the sorted data on the screen. What I need is when the export control is fired, the exact gridview or newly sorted gridview is sent to an Excel spreadsheet. Here what my excel export looks like:

I've got a Gridview bound to an objectdatasource. Sorting is enabled in gridview, but objectdatasource isn't doing any sorting. I can pick up the unsorted datatable from the Selected event of the objectdatasource, but I really want the sorted version. Is there any event on the gridview where I can access the sorted dataview it must be using internally?
Why am I asking? We're using paging as well (i.e. truncated data in gridview) and I want to loop through the full sorted dataview to find the primary key value to set selectedindex.

I have a DataGrid that has event handlers bound to SortCommand and PageIndexChanged. How can I determine if those event handlers are about to be called, say on page_load? These events will fire just fine after page_load, but I'd like to know at page_load if they are to be fired.

I have a stored procedure in my database that sorts a dataset by distance from the specific address input by the user. The distance is created among each individual users query and the sorting of distance occurs within my stored procedure, the distance is not returned in the output. Is there a way I can create a temporary column that returns the distance so that I can give the user an option to sort by distance?

I am having a DOB field in database of type Datetime.I am retrieving this into a gridview .I want to display only date into the gridview in 'DD-MM-YYYY' format and that to in sorting order. How can I do that. I know that by converting DOB to varchar and using SQL Date formats codes(103,105...) I can do that but I can't able to display in sorted order as it will check only the date part and sort the dates. It will not chk the month & year. And I also want the user to insert the date in 'DD-MM-YYYY' format and this to be stored in database. How can I do this? Pls respond me ASAP.

I'm trying to extend the GridView control to enable sorting and paging for any situation.
When using my control I am fetching data from a database and filling a DataSet with it, then binding the GridView upon every page load. My first question would be, is this the correct approach?
To sort the GridView I am overriding the OnSorting method which stores the sort expression and direction in the ViewState, then creates a DataView and utalises the Sort method to sort the underlying data. It then sets the Data Source to this DataView and rebinds the GridView.
Paging is handled by OnPageIndexChanging which simply sets the PageIndex property and again rebinds the GridView.
My problem is; when any control causes a postback my GridView is no longer sorted, presumably because it is persistently rebound. If I don't rebind it then the GridView is empty on postback since the data isn't automatically stored in the ViewState. I have considered saving the data source in the ViewState but I would assume that this is bad practice for large amounts of data? - also DataViews are not seralisable.
The only solution I can think of currently is to override OnDataBound and sort the data every time. This results in a double sort when paging triggers a postback which seems inefficient. Code illustration of this below,
[Code]....
I'm looking for the cleanest 'best practice' solution as this is a learning exercise more than anything else.
