I have a dataset generated from xml from a web service.Data needs to be sorted by date order descending, I cannot get the web service changed so thought I'd try:
Code:
repeater1.DataSource = dsCombinedBlock.Tables(2).Select("Status < 3 and status <> 99", "DateReceived desc")
However the dates are treated as a string so the results look like
28/06/2011
27/06/2011
27/06/2011
02/06/2011
01/07/2011
How do I get the proper ordering applied.

I have a datatable with the ordering of its DataClassIndex column before editting:
DataclassIndex 0 1 2 3 4
When I start modifying some other cells in this datatable, the ordering of DataClassIndex column changes to something like this
DataclassIndex 3 4 2 1 0
How can I modify a datatable content without altering the original order of the datatable.

'DataTable' is an ambiguous reference between 'System.Data.DataTable' and 'Microsoft.Office.Interop.Word.DataTable'

I came across the below article, I would like to know how to properly respond to the drop or stop event so that I can show the Save button only once someone changed the order. In other words, I would like the Save button hidden initially, only to make it visible once a drag and drop has occurred.

the best way to do the following (I'm using a simplified example of my actual problem?Say I have a customer ordered items table with fields: oItemId, OrderId, ProductId, ItemPriceI want to query where OrderId >oMin && OrderId <oMaxand for each value of OrderId I want to find the record with the highest ItemPriceso for a single OrderId the query would be:(from o in context.orderItems where OrderId==x orderby o.ItemPrice select o).first()but OrderId isn't a single value. If I modify the where clause then this query would still produce a single record whereas I want a single record per OrderId.oh and as an additional question: does anyone have a compact test for whether a record exists. I am using the querystring to specify an Id and there are numerous things that I want to protect against. If I do:
var myRecord = from o in context.orders where o.orderId == request.querystring["Order"] select othen this fails if the querystring isn't specified. So first I test that the querystring != nul . Then I need to do:bool recordExists = (myRecord != null)because even if the querystring is specified it may be an invalid orderId and thus the query returns no results. Is there a shorter/simpler way to calculate the result. I have not yet got to grips with lambda expressions and I'm not sure whether there is a better approach with lambda expressions.

This was programmer error - a problem with my SQL. I am populating a slideshow extender control successfully from a list of images maintain din a MySQL database. I have created a "back" button that executes the following javascript:
[Code]....
This correctly goes back to my web service method that fetches rows from my database. I issue an "order by" in the SQL to sort the rows returned in descending tiome order and have verified that they populate the slide array in that order. However, when the page renders, the slideshow appears to play them in almost a random order. Is there any trick to getting images in a slideshow array to play in a particular order?

I hoping someone may be able to point me in the right direction for this. Basically Im writing an asp.net web control to dynamically display a set of data based on field data stored in the database.
I want the control to create a dynamic asp table from a set of data from the database, however I cant get my head round the query needed to order the data into a list that I can create a htmltable from (if that makes sense)
my data looks like this, where I have a field name, the order the corresponding control will be rended in, and the number of columns that control takes up in the asp table:
Id | FieldName | ColumnSpan | Order ...
-----------------------------------------
1 | UserName | 1 | 1
2 | FirstName | 1 | 3
3 | LastName | 1 | 4
4 | Email Address | 2 | 2
5 | DOB | 1 | 5
6 | Notes | 2 | 7
7 | Password | 1 | 6
8 | UserID | 1 | 0
I have made a couple of attempts at creating a stored procedure that accepts an integer representing the number of columns the table will have, with no real progress. I would like the query to return something like the following (if the input parameter was 2 (columns)) - where the fields are grouped into logical rows
row | FieldName | Order
------------------------------------
1 | UserId | 0
1 | UserName | 1
2 | Email Address | 2
3 | FirstName | 3
3 | LastName | 4
4 | DOB | 5
4 | Password | 6
5 | Notes | 7

I have a few tables, Listings, ListingImages and a few others related to Listings. ListingImages is related to Listings so that you can have many ListingImages per Listing.
When I query this table I do;
[code].....
Now this is fine. However, I now want to sort the ListingImages independently within each Listing (by an ImageOrder column I have in that table).
How can I do this and pass all my Includes(...). Would it be bad form to sort the ListingImages within the View as this solution seems to work?

hey folks I got a general question that maybe some of you can just weigh in. I developed an online store for a client and people place orders online for a food ordering place however I am trying to find the best way to have the orders show up for them at the store. Currently I am sending an email and an autoprint software prints it out which works most of the time but not good enough sometimes it doesn't print. Anyone had similar issues or have other alternative solutions you may have heard off? Like I said the site sends an email to the customer and the store's email account.

Dim dt As New DataTable Dim da As New SqlDataAdapter(s, c)
c.Open()
if Not IsNothing(da) Then
da.Fill(dt)
[code]...
When I call da.fill I am inserting all records from my query. I was then hoping to filter them to display only those where the GroupingID is equal to 0. When I run the above code. I am presented with all the data, the filter did not work. Please can you tell me how to get this working correctly.

I have a DataTable of available time slots. I have another DataTable of reserved time slots. I need to remove from the list of available slots the ones that have been reserved. The blocks are in 15 minute increments, but one of my problems is that the reservation can be longer than 15 minutes. I've had some luck removing one or two, but not all of the required columns.
Here's my code (it doesn't work right now).

I have two datatables, I want to get all records which are in one datatable but all matching records which exist in another datatable should not be available.
In terms of set, you can say that record which are in 1st datatable but not in 2nd DataTable.

now when i type something in header Search cell , it shows the data of first page index only , it won't show me data from 2nd page index .. here's my code :
protected void PhasesTempGrid_OnDataBound(object sender, EventArgs e){
GridViewRow row = new GridViewRow(0, 0, DataControlRowType.Header, DataControlRowState.Normal);
for (int i = 0; i < PhasesTempGrid.Columns.Count - 1; i++) {
TableHeaderCell cell = new TableHeaderCell();
TextBox txtSearch = new TextBox();
[Code] .....
My gridview is in update panel therefore i did this in .js script :
var prm = Sys.WebForms.PageRequestManager.getInstance();
prm.add_endRequest(function () {
$(document).ready(function () {
$('.search_textbox').each(function (i) {
[Code] .....
Here's my code structure for gridview :
<asp:UpdatePanel ID="ConstructionActPhaseUpdatePanel" UpdateMode="Conditional" runat="server">
<ContentTemplate>
<asp:gridview ID="PhasesTempGrid" ClientIDMode="Static" OnDataBound="PhasesTempGrid_OnDataBound" allowpaging="True" OnPageIndexChanging="PhasesTempGrid_OnPageIndexChanging"
