I am trying to use data from the following row of a query to create a new field. Below is my table layout. I can use logged on time to figure out the logout date but I want to grab the next login time so I can figure out the time spent logged out.
|-Login Date---|-PersonID-|-LoggedOnTime-|
6/30 12:00pm-----100---------------3600
6/30 01:00pm-----100---------------4000
6/30 03:30pm-----100---------------5500
i have two sqldatasource controls. one i use to display data in textbox's ,filter'd by a select parameter in page behind code. Once checked, i want to copy this data to the other datasource ,by selecting checkbox.Then display this data in detailsview control.
At present the two datasource controls declared , render data to the page simultaneously during pageload. I want to first check data in textbox's from first source, before second datasource is rendered to screen. note, both are filtered by a page variable. i wish to leave the textbox datasource control in situ, as other controls and code depend on it.The other detailsview datasource is my problem?
ASP.net SQL datasource C# code behind
I want the webpage to show a message that there is no data selected,
Instead of showing blank details view
here is a picture of blank details view:
[URL=http://img28.imageshack.us/i/errorks.jpg/][IMG]http://img28.imageshack.us/img28/4328/errorks.jpg[/IMG][/URL]
What C# code do i need to use so that, whenever I enter that page, only an error message will show up
instead of the details view ..etc.
Scenario:
I am creating a custom gridview control which has a custom CheckBoxTemplateField column (deriving from TemplateField class). This template field column has custom Checkboxheadertemplate (implementing ITemplate) and CheckboxItemTemplate (also implementing ITemplate). In InstantiateIn method of both templates (header as well as Item template), I am adding a checkbox control which has Autopostback = true.
My requirement is:
I want to mark all the values in the binding column of datasource if checkbox in headertemplate is checked. I dont want to mark only rows visible on grid. I WANT TO MARK ALL ROWS IN DATASOURCE. I want to do this in _CheckedChanged event of checkbox in header template.
Problem I am facing: When I check/uncheck the checkbox in header, it postbacks. so in OnCheckedChanged event, gridview's datasource is null. Secondly, in any event of gridview, I could access only those rows of datasource for which corresponding rows are visible in gridview through Gridviewrow.DataItem property. But I want to set it for all rows in datasource.
This is the first time I have been working on databases and I am trying to insert data using an object datasource but no data is being inserted and no exception is thrown. I'm not sure where I am going to wrong. I am putting user data into session variables and inserting the session variables into the dataacess class layer and have a try and exception but nothing being thrown. Any help would be really appreciated because I don't know even where to start looking with this or how I can get the error to be thrown. Please see some of my code below to give an idea of what I am doing

I have a lot of members data to enter into the ASPNETDB database. How can I read this data from an Access data file and input into the SQL database. All data is for user Names and Password,
View 1 RepliesI am using an SQL Express server hosted on a different machine and it is listed in my server explorer just fine. It is listed as my connection string in my web.config just fine as well and lastly it seems to sync just fine with my asp.net membership tables. My question is does it need to be listed in my app data folder of my site? Currently I have the ASPNETDB.mdf connection listed, which is apparently just a local sql express connection. The database I am using in my webconfig and other files is not listed so do I need to add it there?
Second question is about DAL, Data Access Layers. I have mostly been using presentation level SQL commands with my data presentation controls. Manually entering separate select, insert and update statements. I just went through a tutorial that stated the best way to interact with your database in asp.net is with DAL using table adapters. It mentioned that it gives you the ability to use strongly-typed references to each row. My question is can I use the same method multiple times on a single page. For instance a method inside an adapter named GetProductsByID(@ID) ? What if I want this bound to three different gridviews on a single page? Anyone have any other general things to point out about using DAL over presentation level commands?
I developing a application in Asp.net3.5(C#) and Sql server2005, my problem is that i have to Import data from diffrent-2 data sources like MS Access, Oracle, ODBC, XML to my Data base(in Sql server) using C# code. I don't know any thing about importing data from these data sources.
View 1 RepliesAre there scenarios where it makes sense to encapsulate a data access layer (of a ASP.NET webapplication) with WCF or WCF Data Services ? Makes it sense to use a service inside the application ?

View 2 RepliesI'm populating a grid view with data from an SQL datasource. The database has a a list of performing artists and lots of details. The gridview initially, shows the ArtisID (Primary key) , and artist name and music style. So far this is all simple and easy. This is done.
Now I want to be able to click on the ArtistId (Select Column) and move the customer to another page where I show indepth details about the artist. How do I do this???
In Vb.net I had a 'Celldoubleclick' event, and I redirect the client. But how do I accomplish the same in asp.net? I already have the primary key value

Is linq just for retrieving data or can you send data to the database using it?

I have SQL Server Database Primary Data File.
I want to recover the data from that file in to my data base which has the empty tables.
I have Microsoft SQL Server Query File which contain the table structure.
I'm trying to make a dropdown list with data available based on the users login name. Heres what I have as my SQL Query in the SQLDataSource:
SELECT Client_Name, Client_ID FROM Client WHERE (Client_Name LIKE '%@Client_Name%')
So say if the login username is "User1" but the database client name is "User1 Steel" I want the dropdownlist to pull "User1 Steel" as the display and Client_ID as the value from the dropdown list.
I am familiar with populating a gridview with data. I am able to bind the Data pulled from the database into the gridview
gridview.DataSource = myDataTable;
gridview.Databound.
If I write the following code, teh gridview will no longer show the data
gridview.DataSource = null;
gridview.Databound.
My question is , I want to make the same thing with a user control that contain a gridview. when I use the user control in an aspx page, I am able to populate it with data, but when I try to make this code, the Datasource does not show, instead, I see .DV. So I tried this code but then , I do not see DataSource property instead I see DV (DataView), when I put .DV = null, I get an error message that the object is not in existed. any idea how to clear the user control gridview from its data.
I want to do is create a simple page which allows a user to post data into a data table. It should not allow them to view, update or delete any data.
Is there a good online tutorial which would guide me through how to do this in Visual web developer 2008?

View 3 RepliesOn my .aspx code I have
<asp:ListBox ID="LBcategories" runat="server"
DataSourceID="SQLCategories">
</asp:ListBox>
When I was creating a datasource for the List box - it showed the correct data,but when I tested it on the Web - I see a listbox with 3 lines of value:"System.Data.DataRowView". After manually deleting a row from the database - I see only 2 lines. After deleting all rows from the table - the listbox is empty.
So why I don't see the table values, but the string "System.Data.DataRowView"?
I have a query that gets all item attributes using the query:
SELECT AttributeName, AttributeValue, ItemName from ItemAttributes
But I will need to write .Net code to cross-tabify this query's data.
How can I cross-tabify the above query using SQL Server code so AttributeName appears as table heading and AttributeValue, ItemName as column values?
I have two formviews and two datasources on a page.
The first shows data from datasource 1 in various labels.
The second shows only a 'new' button to switch to insert mode.
On the seconds insertmode, id like the data in textbox1 to be already filled with data shown in the first formviews label1 (or [id] from sqldatasource1 if thats better?)
