I right click on a TableAdapter, select Add Query, select using QueryBuilder, then select a field to filter upon, and add Filter as =@BookStem. Automatically the QueryBuilder adds the WHERE clause to my new query:HERE (BookStem = '@BookStem')When I press OK, I get "BookStem in expression is not part of the query". And filtering doesn't work.
View 1 Replies I have a standard gridview, with the standard paging and sorting interface enabled.The application holds appointments for three organisational units, with a maximum of 3000 appointment records being returned across all three units. The appointment records are quite small.
The choice I am faced with is to:
1. Have an Org Unit dropdown which returns to the datasource on change of selection and at inital databind, and returns appointment records for one org unit at a time i.e. approx 1000 records.
2. Have the objectdatasource return all 3000 appointment records for all org units at initial databind, and filter the objectdatasource by org unit on change of selection, thereby saving a trip to the datasource.
I guess the question boils down to identifying the point at which querying the datasource by org unit is more efficient than filtering the records returned by org unit.
Is 3000 records a lot for a gridview to be paging and sorting etc.
There are several articles and blogs that are sort of about this subject but I haven't found one on point. Wondering if anyone has done this? Using VS2008 creating an ASP.NET 3.5 app with a strongly-typed dataset connecting to an MS SQL backend. In one TableAdapter, I have a custom Insert statement that inserts the record into the primary table. There are two other tables the also need records inserted into them and those records contain the record ID from the primary table. Here's an example of what I'm trying to accomplish:
[Code]....
I have this Insert statement working fine: [Code]....
It inserts a new record into a single table. The PK is a field named QID.what the equivalent Update code would be? I'm not sure of the syntax for the Update values (old and new) and Where clause.I'm assuming something beginning with: existingQ.Update
I have a quite baffling problem. I've created a Table adapter with 3 queries. 1. GetMemberData() - Return ALL rows. 2. SearchMembersLastName(@q) - Return specified columns from rows that have a column starting with a specified letter. 3. GetMemberDataById(@id)
- Return all rows matching a specified ID.
The Problem is that SearchMembersLastName(@q) is returning ALL coloumns instead of just the ones I want. Here's the query that's in the Table Adapter:
[Code]....
The problem is that it is acting like:
[Code]....
Here's the code that's calling it:
[Code]....
I just can't figure out why this is happening, any help will be greatly appreciated.
I create Dataset(Add new item dateset(the name is myDataset)), after
that I made a simple TableAdapter(myTableAdapter) sql query, I want to know how to connect with code to this tableadapter and then with DataGrid(I don't wont to use wizard).
I am creating a TableAdapter using corresponding wizard, with a GetDataByID() query. The select statement is like this:select * from books where ID = ?Thus books are filtered by ID. But in case a null is passed as a parameter, I want to select all records rather than none. Could you please tell me how I can do it?
View 4 RepliesI have created a function that is called when a user wishes to upload a file to the database. The problem I am having is that it won't write the files to the database anymore. This function used to work before I implemented a treeview (which connects to the database). I am struggling to see how the treeview could have cause the file upload to stop working (the error may not even be related to the implementation of the treeview).
The error message I am receiving is: 'Update' is not a member of 'CMS.SiteFilesDSTableAdapters.SiteFilesTableAdapter'.
The code for the upload function is:
<System.ComponentModel.DataObjectMethodAttribute(System.ComponentModel.DataObjectMethodType.Insert, True)> _
Public Function AddSiteFile(ByVal FileData As Byte(), ByVal FileName As String, ByVal FileDescription As
[code]....
It is throwing the error at: Dim rowsAffected As Integer = Adapter.Update(SiteFiles)
' Return true if precisely one row was inserted, otherwise false
Return rowsAffected = 1
EDIT: I managed to solve this problem by following:
http://www.asp.net/%28S%28pdfrohu0ajmwt445fanvj2r3%29%29/learn/data-access/tutorial-69-cs.aspx
Basically, I had used an Inner Join to gather all the fields, and table adapters don't seem to like them.
INSERT INTO [SiteFiles] ([FileData], [FileName], [FileDescription], [FileType], [FileCreated], [FileCreatedBy]) VALUES (@FileData, @FileName, @FileDescription, @FileType, @FileCreated, @FileCreatedBy)
I'm lost as to where to look next. Here is a sample of what I'm doing:
[Code].... The related tableadapter insert statement was autogenerated by VS2008:
INSERT INTO [ProductCycleCountItem] ([ProductCycleCountLocationID], [ProductID], [CountOnly], [Status]) VALUES (@ProductCycleCountLocationID, @ProductID, @CountOnly, @Status);
SELECT id, ProductCycleCountLocationID, ProductID, CountOnly, Status FROM ProductCycleCountItem WHERE (id = SCOPE_IDENTITY())
With multiple users it's as if it was returning @@IDENTITY instead of SCOPE_IDENTITY(). The table will look like this:
id Location product
1 A 5321
2 A 8273
3 B 2827
4 A 1743
The returned dataset will look like this:
id Location Product
1 A 5321
2 A 8273
3 A 1743
Is it maybe a SQL Server (2005) setting that's incorrect?
Going to start this thread over so that it makes more sense.Anyways, my problem is that when trying to configure my ObjectDataSource in design mode, it only gives me 2 options and never gives me the option for the one I need. The other 2 work fine, but for some reason, this 3rd one will not show up in the list.I have a webpage with pics illustrating how I have it setup and the problem ----------> https://sites.google.com/site/configuringobjectdatasource/And I have another webpage with pics illustrating steps I have taken to fix this problem but still nothing -----> https://sites.google.com/site/configodspart2/what is going on and why it will not show up in my list when I try to configure?
View 3 RepliesI need to insert two rows into a tableadapter - and then take the identity column from each row and update them into a column on each row.
My problem is that I cannot update a column on a newly inserted row. Stepping through the code seems to indicate that I have updated the column, but when I check the database - the column indicates null.
I have tried calling Update on the TableAdapter, then performing the update on the column, and then calling Update again, but the update still isn't taking.
I have a dataset with a table adapter that has several queries. I want to execute on of the queries and fill a data table but am having trouble with this operation. Am I invoking my table adapter incorrectly? See line 56.

I have a FileSystem based asp.net 2.0 app that uses Sql Server 2005 Express database.
I have only one dataset for this app with only 4 tables. After i have completed it to a part, a co-worker have added some Classes to it, which are not in same namespace of myBLL classes.
Then i tried added a new table to the dataset. It like all other tables in that dataset uses SQL Statements to access and manage data.
The problem started after i added that new table. I cannot access it from code. I can access all previous TableAdapters but not this new one.
I have a dataset with several tableAdapters in it. For some reason, one of them that I created doesn't show up when I try to put it into my objDataSource?
I can access and use it from codebehind (testing purposes for this post.
I've got an odd problem and can't figure out what's causing it. We've got 2 different DataSets in the same project and I'm seeing different generated code from the MSDataSetGenerator. Both projects are .NET Framework 4.
In one DataSet, I can open the .Designer.cs file and there's a line like:
[Code]....
This essentially exposes a Transaction property to any partial class I create so I can do with it what I want (by setting it to something).
In the other DataSet no matter what I try to do, this Transaction property never gets generated. I've right-clicked on both DataSets and chose "Run Custom Tool" to get them to regenerate (I've even tried deleting the .Designer.cs file before doing this) and they both get generated the same.
I tried to make sure all the properties of the DataSets were the same. Both are using .NET Framework 4.0 and VS2010.
The file that does not generate the Transaction was from a .NET 1.0 asp.net web site that has continually been upgraded through different .NET versions. Right now it's at 4.0 but I don't know if that would have anything to do with it.
I spent about 60 minutes sifting through search engine listings trying to figure this out and couldn't find an answer, so I decided to make this post for others.
Situation: Using a Stored Procedure to insert a row and return the new row ID, explained here. In my case, I used the Idenity_Scope to return the new row, like so:
[Code]....
Next, following steps as described in link above, went into the dataset XSD page, configured the table adapter to use this stored procedure. By default, it wanted my return value to be set to some value, but I set to allow Null (makes sense, since I don't want to pass the value in, I want to get it out, so it should be null to begin with).
Problem: Where I ran into an issue was in the method to call this stored procedure. The intellisense displayed the prototype it was expecting, basicly like this:
[Code]....
I fill a GridView from a ObjectDataSource that points to a Typed DataSet.
I need to read a couple of row columns from the object data source that IS NOT part of the Gridview.
So far, I have found out that ObjectDataSource.ObjectDataSource_Selected is the right event to do this.
Examples on the internet refers to e.OutputParameters, but that appears to be empy even though rows are returned.
e.ReturnValue seem to contain a type related to the row type, but I cannot interpret this either.
in generate the Stored Procedures when using Create TableAdapter configuration Wizard in VS.it can not generate the Stored Procedures for Delete and Update Commands, but it generated for Select and Insert. i tried many times, but still get the same problem.
View 2 RepliesSo, I have 3 table adapters in my dataset, and trying to configure the objectDataSource will not give me the option to select the correct table adapter.
I set up a temporary website to illustrate what I am talking about, along with pics, not much, just 4 pics.
https://sites.google.com/site/configuringobjectdatasource/
The first 2 pics are irrelevant but just in case anyone thinking I don't have it set up properly. The other table adapters are working fine, which I have gridviews being populated etc.
why it will not give me the option to select aspnet_GetRecordDatesTableAdapter?
I currently have a common file that's responsible for exporting the users GridView to a CSV file which works fine, mostly. The problem is that it only exports the current gridview display, and being that I have it paged, it can be cumbersome to get all the data to an excel sheet when there can be upwards of 20 pages of data. The GridView has a LINQ datasource as follows
[Code]....
How do I get the results of the preceeding datasource? Or is there a better way to get ahold of that data before it is paged?
This is not straight forward to explain but basically i want to only get the current weeks data in a table, i.e. if its say thurs or fri and i run the report i just want to filter from the previous Monday every time.
I dont want to use a parameter because there is another table that i want to see ALL data from way back.
So, if i ran the report today (28th april), the table would show Monday (26th), Tuesday (27th) and today Wed (28th).

I'm using log4net to log my web app's progress, using Log4PostSharp to AOP-injectify all methods. This has the desired effect of logging (almost) everything and is fine.I now have a requirement to log JUST Page_Load methods to a file / console. I can obviously hamstring the log4postsharp class to do that, but then I'd be losing all the other logging.I've been looking at filters in log4net, starting with the StringMatch filter, but that only looks at the message being logged, and I'm after the method name. This put me onto the PropertyFilter, but still with no joy. My log4net.config snippet is thus:

I'm working on an application that allows our Office Services people to schedule employee location moves. The page I'm currently working on allows for modification of scheduled moves. When the user attempts to save changes in this page, the app runs a stored proc to see if there are any conflicts, e.g., someone already sitting in the new location, someone scheduled to move into the employee's location before the employee is scheduled to move, etc. These conflicts, if any, are then displayed for the user and he/she has to make changes to one or more moves to resolve the conflict. This all works just fine. My problem comes when the user has resolved all the conflicts (or thinks he or she has). I need to check again to make sure that there are not still conflicts somewhere before allowing the data to be saved back to the database. So, I've got data for at least two scheduled moves, but this data does not necessarily match what's in the database.
I want to run the same stored procedure that I initially used on this dataset. The stored proc uses three database tables, plus the proposed move information to check for conflicts. What I'm trying to do (but please tell me if there's a totally different approach that would be better) is I've created 3 DataTables, using the 3 tables that my stored proc uses. The tables are Employee, Location and Moves. I've then put all these tables into a DataSet. I've updated my Moves DataTable with the proposed new move information. Now I want to run my stored proc on this dataset to see if I get any rows (i.e., if there are still any conflicts). But I can't just run the stored proc; it references the tables in the database. I want to run my stored proc on this DataSet. The stored proc is very long and takes 5 parameters which are referenced all through it, so I don't want to just create a DataViewManager using the SQL.
I have a GridView that's currently bound to an ObjectDataSource. I would like to see if it's possible to instead bind it to an EntityDataSource. However, I need to be able to apply custom filters to it.
One of the filters corresponds to a bit / boolean property in the database / EntityDataModel. It has 3 possible selections:

How can I accomplish the same thing in an eSQL Where clause? There is no COALESCE function, is there an equivalent?
