Data Controls :: Fetch Top N Records From DataTable Or DataSet In Net Framework 2.0

May 7, 2015

Aspx code:

MembershipUser m_user = Membership.GetUser();
DataTable dt = new DataTable();
dt.Columns.Add("SenderUser");
dt.Columns.Add("RcvUser");
dt.Columns.Add("Message");
foreach (ListItem li in lst_Users.Items) {

[Code] ....

I am calling "Application object" from above aspx page into web service page as below:

[WebMethod(EnableSession = true)]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public string WebMessage() {
List<string> list = new List<string>();
DataTable dt = ((DataTable)HttpContext.Current.Application["Message"]);

[Code] ....

I want to know that the approach im using in Web service page to fetch top 5 messages from Datatable is correct or not? How to do that without using LINQ as I am using framework 2.0 ...

ADO.NET :: FlexCel: Entity Framework -> DataSet / Convert Data In Gridview To A Virtual DataSet?

Mar 31, 2011

In my project I work with Entity Framework (LINQ to ENTITY). I only have ADO.NET Entity Data Model and a DAL (Data Access Layer). I also get the data due a WCFClientService. I have a gridview that needed to be exported in Excel.

FlexCel is a tool for generating Excel files based on a template. The only thing I see in demo's is that they work with DataSets.

Is there a way to convert the data in my gridview to a virtual DataSet?

Forms Data Controls :: Bind Data From DataSet (DataTable) To A Selectrow DropDownList In GridView?

Nov 19, 2010

I have a Gridview and two link button in that GridView , one link button click is to add edit row ( Edit ), one link button click is to select row ( Select ). I have a dropdownlist inside row which selected when i click link button Select in the gridview edit template, as of my business logic i need to show the dropdownlist only when the user clicks Edit button and when the user clicks Select button . That mean when the user clicks Select button then they clicks Edit button on the gridvview i should allow him to edit the dropdownlist (showing the value to the user through a label).

ASPX CODE

[Code].... C#

When I click Select link button , then I click Edit link button . They have errors : Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index" I don't know what error?. How to fix it
