Access :: AccessDataSource : Query / Every User Getting Everyone's Data?
Nov 6, 2010
I have a GridView where I am displaying the students List who ware absent for "ASP.Net Class" If Teacher 1 login then it is displying all the records who ware absent and same for remaining teachers. I want to display those records where TecherId matched..
I wrote query like this :
Select StudName FROM Class where Status LIKE 'ABSENT' AND Teacher Id =?
But every teachers(User) are getting everyone's data....
I am using AccessDataSource and displying in GridView....
I'm trying to display all orders placed and I have a primary accessdatasource control that has a select query to get the customer information and the orderID. I want to use the orderID value from this first query as a parameter for the secondary accessdatasource control that selects the product information of the products in the order. In plain english, I want to:- select product info from product table where orderID = ?(where ? is the orderID value from the first query)
I have tried the <%#Eval("OrderID")%> but I get a "server tag not well formed" error, but I do get results returned when I just type the order ID in, but obviously every result (order) just contains the same product info...
When I add an AccessDataSource and attempt to configure it, the "Advanced SQL Generation Options" panel opens, but checkboxes "Generate INSERT, UPDATE and DELETE statements" and "Use optimistic concurrency" are sometimes grayed out.It appears that this happens when a table is specified that contains a foreign key, and it also seems that any Update query statement I specify in conjunction with a related databound gridview doesn't "take". What's the story here? Is it not possible to update a database table from a databound gridview control if the underlying table has a foreign key? Or is something else going on?
I'm using an access database that has an AutoNumber field as the primary key. After adding a record I'd like to retrieve the ID for the record that was just entered, however, I'm not able to figure out how to do this in ASP.NET using standard AccesDataSource and FormView functionality. My goal is to retrieve the ID so that I can then use it to add an additional record in a child / sub table.
I could do it strictly using vb.net and forget about using the InsertCommand for the AccessDataSource and it's built in functionality. However, that would require a complete rewrite of some other items, accomplish this using the standard AccesDataSource functionality.
Below is a sample of something I've tried to do using "Direction='Output'" on one of the ID field for one of Insert paramaters (source: http://www.4guysfromrolla.com/articles/050207-1.aspx). The plan was to then caputre that "output" using the my "_OnInserted" sub procedue. However, apparantly I'm not able to use this with AccessDataSource. Did some research and saw that I'd have to switch to SqlDataSource which I'd rather not do cause all other pages use AccessDataSource and I'm having problems defining my connection string with it.
I have my Access database bound to a Gridview and an able to Edit and Update the Grid as long as all columns are set to ReadOnly=False. If I make one or more columns ReadOnly=True I get the following error on updating: You tried to assign the Null value to a variable that is not a Variant data type How do I get past that problem?
I have a data type mismatch while inserting into a number field in an access database using a parameterized query.I think this should be pretty simple but I am still learning a lot.

I have some commented out as I am working one field at a time. The working fields are textboxes and the non working ones are dropdown lists. But I think it may be the field that the list is drawing from? Not sure.
How do you databind from an AccessDataSource to a Label Control on page_load? I know you can use eval, but how do you associate your eval statement with the correct data source control?
I have an accessdatasource linked to MS Db query with three fields (date, SR, & CR).I also have an asp.calendar control on my aspx page.I am trying to figure out what OnDayRender code (or any other code) that I would need in order to change the cell color on the calendar based on the value of SR or CR in the query
I have a search box on a web application that is to use a query I have built in Access to search through projects to find any that are related to the text entered in the search box.
The query in Access is just made up of parameters that use wildcards to search through all the fields. In Access the query works fine and returns the correct data but when I try and link this all up to a ListView in Visual Studio, the ListView just diplays the message "No data was returned"
Below is my page-behind code, hopefully you can see why it is not working but it looks like it should work to me.
Can a query output made in MS ACCESS be accessed as a database in Visual Studio 2008?
I have a Parent and Child Table in MS Access with a one-to-many relationship. I created a query in Access that would produce a result table and I want the contents of this Query to be displayed in a Data Grid in Visual Studio 2008.

I'm writing a web service that needs to query an Access 2003 database (.mdb). I've found the following code in doing some research on OLEDB connections and queries:
[Code]....
Errors are as follows:
Error 3 A field initializer cannot reference the non-static field, method, or property 'CompleteRentalls.completedb.sqlString'
Error 5 'CompleteRentalls.completedb.da' is a 'field' but is used like a 'type'
Can anyone help me rectify the above code such that the query results are returned to my datatable?
I have a webpage with a gridview on it which is bound to a table in an Access database. So I now drop a dropdownlist on the webpage and when the Choose a Data Source popup appears if I select my Access data source there is nothing in the select a data field for display and select a data field for value fields on this popup. So it appears I have to create another Access data source. But why if I already have an Access data source on the same database? What am I doing wrong?
I am attempting to insert into two tables at once, but it's inserting blank values into the first table, and then correctly inserting the values into the second table. here is my codebehind, I can post the rest of my code if needed.
[code]...
Even when I comment out the second insert command, the first one still inserts null values.
I executed the following sql command, and got error "Operation must use an updateable query.".

The database is access 2003. The tables are T1 (code (key), n) and T2 (code(key),num). Why do I get this error and how do I solve it? EDIT: Found solution somewhere else.
I'm working on a portal, and I need to check users conection on the ldap.
And if users are members of a special group then it works.
I've exactly used this link to make it works : http://msdn.microsoft.com/en-us/library/ff649227.aspx (almost work)
My point is : my ldap path seems good, no error anymore, when I log with my username and password.But when I querry it, it returns null, but I'm sure my user is in the group :
// Bind to the native AdsObject to force authentication. Object obj = entry.NativeObject; DirectorySearcher search = new DirectorySearcher(entry); search.Filter = "(SAMAccountName=" + username + ")"; search.PropertiesToLoad.Add("cn"); SearchResult result = search.FindOne(); if(null == result) { return false; }
I'm a normal user, i test with my account. I'm a member of the group that I'm looking for.
I wish you are having a wonderful day Today I encounter a problem which I am unable to solver yet. have a e-mail subscription area and I am using accessdatasource for that. Also I am inserting the e-mail adress into database with AccessDataSource InsertCommand in aspx page not in codebehind. What I want is that;I want it to first check for the textbox-email value if it exists already or not ! Then if exists, I want to make "LabelOutPut.Text = "Already Exists !"" But if not exists, I want to do on button click that; "AccessDataSource1.Insert() and LabelOutPut.Text = "Subscribed !"
I'm new with programming. I have a GridView that have the specific user data. When the user log in I retrieve the data for that specific user. All I need is; How do I make the gridview get the data of the logged user using a datatable that has a query. Just bind it with the datatable.This is some code that other programmer made, I continue his work.
M was creating web page. Then next day when i starts my project again, everything was running properly, but now in all design page the tool of AccessdataSource is not showing in Design page. Though its working but it is not showing in design page. it shows in other system. So due to its invisibility , some times i create four-five datasoure in one page. Same problem also happens in sqldatasource and all other datasource.
I have a shopping website, I want to save all the user information (e.g templates, color preferences, shopping cart data, previous page, order number etc..) in SQL server.
For this either I can create my own functionality which will log everything to some sql database table and later that table can be used to show filtered reports to the admin.
Or I can use asp.net's built-in personalization concept. But in case I am using the personalization, can I/admin fetch the presonalization data of another user for reporting purpose?
Also, is personalization is the right approach to fulfull my requirements?
I need to log every user-action taken on a database using the username of the person logged into my ASP.net application as the identifier in the log. What is the easiest way to do this? I guess that for every method call to my data access layer I need to log the parameters of that call and the username and then call a new "log event" method that writes the details of the call to a table. Am I on the right track?
