DataSource Controls :: Conflict Detection - CompareAllValues Option But Use Only 1 Field To Check Data Changes?
Feb 16, 2010
I have a simple sql server table with around 20 fields in it. I have created an asp.net page which shows the ecords in a gridview & then the selected record in a formview. There may be cases of multiple users editing the same record so i wanted to use the conflict detection in a sqlDataSource to inform users of the conflict. I managed to get this working where i replicated all 20 fields to create the equivalent original_XXX parameter.
BUT i was wondering whether it is possible to show all 20 fields but only use 1 (the date modified field) to check for data conflicts? I have tried to implement this in the following way:
[Code]....
But i've had no luck in getting it working. The conflict detection simply overwrites the changes instead of not allowing the changes and showing the specified error msg (in the onUpdated event). The examples and tutorials i've seen all seem to indicate that each field would need to be compared BUT why can't i simply compare a datetime field which records the last time a record has been updated? Surely, there has to be a better way of resolving the data conflicts than comparing every single field with it's original value?

I have a gridview with two textboxes (first name & last name) and a linkbutton to search results inside the gridview.
I have made select parameters as well and the search works if i write in both textboxes. However, if I leave one textbox blank, i don't get any results.
[code]...
How can I get results from searching only one textbox?

I am using Request.Browser.IsMobileDevice in conjunction with the MDBF file that goes in the App_Browsers/Devices folder [URL] Now using Sea Monkey browser (latest version 2.0.7) IsMobileDevice returns true. Why might this be the case as clearly Sea Monkey is not a mobile browser. In fact, I had the understanding it used a lot of the same core as FireFox (which does not return true)

I have loaded up a gridview object with data. I have turned on Edit on the grid. It lets me edit the data, but I also want to put some code to check for correct data in each field. I tried to assign a requiredfieldvalitor, comparevaliditor but they don't work. Is there an event I can capture to fire up some code before the grid sves my data?

I wanna join all the field as a new col.
but how can i ignore the empty field because i always join the field and separate by space like the following.
select (field_1+' '+field_2+' '+field_3) as new_col from TABLEA
but if the field is empty, then there is the double space
how can i ensure all the space is one space only.

I am trying to run the following SQL query
string strConString = ConfigurationSettings.AppSettings[ "conString" ];
myConnection = new OdbcConnection(strConString);
myConnection.Open(); // open connection
string strSelect= "select * from tbl_howells_product_data where title like" + "'" + strsearch + "%" +"'" + "order by product_id asc";
OdbcCommand myCommand = new OdbcCommand(strSelect, myConnection);
dtrReader=myCommand.ExecuteReader();
The problem is I need to check to see if any data has been returned from the SQL query, if there are no rows/ data returned by the query then I need to display a message to say that there aren't. I know that there isn't a 'number of rows method' for the dtrReader, so does anybody know how I could do this?

GridView bound to a SqlDataSource. GridView.AllowPaging is True. In one of the ItemTemplates I have a LinkButton with a OnClick event.Have a DropDownList for changing GridView.PageSize - done in Page_LoadEverything in of-course in an UpdatePanel.
The whole thing work fine (we are in test fase). The problem is that the LinkButton OnClick event is only being attached to the initial "PageSize" amount of elements. Fx. if I sat PageSize=15 in the <asp:GridView> then change the page size to say 30 from the DropDownList, the page size changes but only the first 15 LinkButtons fire the OnClick event when clicked.
I've tried to do the following:
Attached an "onchange" javascript client event for saving the selected value in a <asp:HiddenField> before postback. Problem here is that the HiddenField value is then only available on Page_Load. By then it's too late to set the new page size on the GridView because the attachemnt of events to the LinkButtons have allready happened - of-course only to the first 15 elements.Then I tried to drop the PageSize=15 in the <asp:GridView> and only sat it in the Page_load. The idea was that with no paging all the Linkbuttons will get treated evenly. That worked, but when I change the GridView page size and click fx. on LinkButton 25, the Click event forks fine but the GridView page size resets to the initial value (15) - no good.
how I can get all the LinkButtons to have their event working, even after I change GridView page size?

I seem to be getting the following error when trying to do an inner join on a new table I have recently created. The only way I have got around this so far is to put "COLLATE SQL_Latin1_General_CP1_CI_AS" into my join. Cannot resolve the collation conflict between "SQL_Latin1_General_CP1_CI_AS" and "SQL_Latin1_General_CP1_CS_AS" in the equal to operation.
I have not seen this error previously when doing joins, and it is a real pain. My only thoughts are that I have recently added the ASP.NET Security tables to my database - could this be causing the issue? Is there a conflict with collation going on? Although all my tables seem to be using the same Collation as the "aspnet" tables when I look at the extended properties of each table.

I have a 20 to 30 fields on a form. Most of them are optional. However, the users can fill out what they want. If a user dosen't fill in a field when data is sent to the database it's sent as blank, instead of NULL. Is there a way I can generically say "for all textboxes if Equals("") then DBNull.Value". Without going through each and every textbox?

Once again, I find myself stuck!
I am attempting to compare one of ASP.NET's membership userID's with the current userID in an SQL query, however because of the "hyphens -" in the uniqueidentifier field type of userID, i am unable to compare the ids. is there a way around this? (in my example, family_id from tblFamily is the userID that has type uniqueidentifier). my code as it stands is:
Dim UserID As String = New String(Membership.GetUser(User.Identity.Name).ProviderUserKey.ToString())
Response.Write(UserID)
Dim strConn As String = ConfigurationManager.ConnectionStrings("ApplicationServices").ConnectionString
Dim SQLI As New Data.SqlClient.SqlCommand("SELECT family_name FROM tblFamily WHERE [family_id] IS " & UserID & "")
Dim sqlCon As New Data.SqlClient.SqlConnection(strConn)
sqlCon.Open()
SQLI.Connection = sqlCon
Dim RSI As Data.SqlClient.SqlDataReader = SQLI.ExecuteReader()
RSI.Read()
Dim FamilyName As String = "0"
While RSI.Read
FamilyName = Convert.ToString(RSI("family_name"))
End While
Response.Write(FamilyName)
RSI.Close()
sqlCon.Close()

how one would retrive a value stored among several values in a single database field?
For example, the MS Customize CreateUserWizard walkthrough [URL] adds the ability to save the users preference for subscribing to a newsletter and allowing their info to be shared as 1 value in the comment column of the membership database. The result ofaspnet_Membership.Comment is Subscribe=TRUE&ShareInfo=FALSE.
My question is if Subscribe=TRUE&ShareInfo=FALSE is in one field of the database, how would you retrieve just the Subscribe=TRUE value from the field and use it to send a newsletter to the proper users while ignoring the ShareInfo=FALSE value?

I am new to LINQ but not >net. I do understand SQLDataSource, etc. I was just told by a coworker not to use a LINQ to SQL Class for my new project (Bank.dbml). I was told to use instead the ADO.Net Entity Data Model (bank.edmx).
BankModel.edmxBank.dbml
When only using ADO.Net Entity Data Model I try to associate a GridView with a new LinqDataSource I get no options. When I add a LINQ to SQL Class I get the option to use it but it is empty. Is this because all my LINQ classes are mapped in the ADO.Net Entity Data Model (bank.edmx)? Can someone tell me (or point me to) what the differences are in these two?
