how to do paging/sorting using Dapper. EF has "skip" and "take" to help with this. I understand that a micro ORM does not have this built in but would like to know the best way to accomplish this.
how to insert records with dapper-dot-net. However, the answers, while informative, didn't seem to point me in the right direction. Here is the situation: moving data from SqlServer to MySql. Reading the records into an IEnumerable<WTUser> is easy, but I am just not getting something on the insert. First, the 'moving records code':
// moving data
Dim session As New Session(DataProvider.MSSql, "server", _
"database")
Dim resources As List(Of WTUser) = session.QueryReader(Of WTUser)("select * from tbl_resource")

I have a WPF ObservableCollection which is bound to a ListBox and I have a Sort() method which when called will convert the ObservableCollection to a List(Of T), and undertakes a sort based on a date/time column within the collection.
The data is sorted, even when new items are added to the ObservableCollection, however the date/time isn't being correctly sorted. The data is sorting based on the date however it is very much random when it comes to the time portion. The following is an example of the outcomes I am experiencing:
[Code]...
Is there anything that I am doing incorrectly in this method that would cause the time portion not be included in the sort? Is there a better way of doing a sort?

View 4 RepliesI'm experiencing a problem when clicking on the page number within my ASP .NET gridview. When I click another page number, I am redirected to another unrelated page within my project.This wasn't a problem until I added jQuery to my masterpage, so I'm guessing there is some sort of conflict in the javascript code. When the aforementioned redirect happens, the page PageIndexChanging event isn't fired and there isn't a postback as far as I can tell. [code]

I am using a standart .net 2.0 Gridview which uses an XMLDatasource to populate the Grid. The Data property of the XMLDatasource is set dynamically which allows the gridview to change based on input.All this works fine however I am having problems with paging.I have set the AllowPaging Property to "true" and set the PageSize Property to "10". The GridView populates fine the first time around showing the first 10 records and the number of pages as hyperlinks at the bottom, BUT when i try to click on any of the page numbers to view them a message box pops up saying "Object reference not set to an instance of an object"..[code]
View 3 Repliesi'm using a datagridview to display the records which are filled in my dataset. however i need to perform paging to display only selected numer of records (e.g: display only 10 records per page) and by using the buttons (like: FirstPage, NextPage, PreviousPage, Last Page) allow users to nevigate through the records. and possibily display the total number of records in my dataset (e.g: |< last <Next 10/100 previous> first >| ) this might sound very simple but i'm new in .net and so far whatever source code i found in google is moslty written in C# which i don't know.

How to do paging for dynamically created datagridview
View 5 RepliesI have a .aspx search screen that displays the results of the search in an asp:GridView component. There can be up to approx 1000 records returned by the search. I want to implememt paging on the grid so that only 15 records are displayed at any one time and the user can page through the results.
I am retrieving the records by passing search parameters to a WCF service which returns a List of particular entity objects. I create a Datatable and insert one DataRow per entity object from the List. I then bind the grid view to the Datatable.
This is how my grid is defined in the .aspx page:
<asp:GridView ID="gridCat" runat="server" AutoGenerateColumns="False" DataKeyNames="CatalogueID"
HeaderStyle-CssClass="fieldHeading" RowStyle-CssClass="fieldContent"

Is there a better way to do this (or am I doing it wrong)? If not, which of the 3 options do you think is the best? I'm leaning towards option 2 as I don't think option 1 is performant and I don't want to be sending loads of unnecessary data back to the browser as per option 3.
I am a bit lost in concept how to implement what i want to do. I have a gridview, a checkboxlist. I bind the gridview on the page_load. Everytime user choose a checkboxlist, the gridview rebind as well. I have something like this now. This is not the actual code. Thanks so much.

So what do i put here in order to allow paging ? basically, I have 2 datatables in the above example. In the actual code, I have about 5 datatables with 4 checkboxlists. I can't use Datasource control. I need to do it in codebehind as all code already exists.
I have a simple ListView with DataPager like the following:

But, how do I count all checked CheckBox in the ListView that has paging?
Iam using nested repeaters with Dataset (not using Datatable) to retrieve information by passing parameters. So far I have bind the two repeaters clearly and everything is working fine.Here the list of messages created by each user datawise(parameter passed) will be displayed, and there could be more than 50 messages created by each user daily, So now I want to do custom paging for each user.But Iam unable to proceed further, as the next, previous, back, first links are placed inside the child repeaters footer template and i coudn't access these links even by findcontrol method.
