I have a program that uses a database for all of its information. The program is just an easier way to understand all of the information.The user uses 1 of 4 search options (FName, LName, MemberID or Startdate). Depending on what they search for depends on which members are displayed in a data grid view.
Upon selecting the desiered member from the data grid view, information about them is then displayed. This information has been split up over 3 tabs called member information, Attendence and payment history.
That all works great. So I now go to the Attendence Tab and wish to update this members attendence by selecting a date from the date time picker, and select the Add attendence button.This also works fine, the attendence is update but the attendence data grid view is not updated automatically.
I have to select the member from the first data grid view to run the code to refresh the members information.So I thought, call the PopulateAttendenceHistory Private sub again and have it update the data grid view... but it still doesnt work.
I have a DetailsView Control but need help with binding, updating and inserting hookup. My code below does not bind and open my DetailsView as I expect it to (either in Edit or insert mode when my page loads.[code]
View 1 RepliesI have students who will be enrolled into a course. The student grid view has many columns like client_no, student_name, date_of_birth, address, etc. There are over 100000 students so I will need to filter the student grid view to find the correct student to enroll in the course. Once they are found, the user selects them and somehow moves them to the enrolled grid view. If a student drops out then they would be removed from the enrolled grid view.This process needs to be easy to understand and use. Are there any examples available or other suggestions on how to do this?

There is a "how do I video" on how to properly control updates, inserts and deletes in multi-user applications on forms that edit master-detail related data. [URL] Massi worked through the process using Order (OrderID is PK) as the master table and Order Detail (OrderDetaiID is PK) as a related table in dataGridView. The dataGridView automatically generate orderDetailID whenever the mouse enters in a new row. I am doing a similar form, but placing order form and orderDetail form in two separate tabs in a tabcontrol, and also using Details view for both tables. When I click "new" button in BindingNavigator, the orderID is automatically generated. If I use dataGridView for my orderDetail tab, then the orderDetailID is automatically generated when the mouse enters. This allow me to insert/update tables correctly. However I need the Details View for my orderDetail form too. How do I get a orderDetailID automatically generated when user insert a new order and have the mouse click on OrderDtail tab?

View 1 RepliesI had to add another table into my database and now I need to go back and update a page that allows inserts into more than one table. I didn't write this page, so I'm trying to clean everything up, but there are some parts that I don't really understand. Now I have broken the page and it only inserts into one table. The very first one that I insert into.ProductName: goes into the Product table.Description: goes into the Picklist table as Data.....it also is supposed to generate an insert into the marketing table based on the PicklistID which is an identity column. The marketing table tells the Picklist table that it is looking for a description. [code]
Like I said before, only the insert that goes into the Product table works. Before I added the Picklist table and tried to reconnect everything, this entire page worked. The code was a lot sloppier and didn't have parameters, so that could also be where I messed up since I am still trying to learn how to use them. I have gotten everything to INSERT except for the INSERT to the Marketing table.
"Deleting rows from multiple tables in SQL 2005". I need to delete all the rows in the multiple rows where it's the same UserId. My Delete command below:
Delete From tableA
From tableA INNER JOIN

tableC ON tableA.UserId = tableC.UserId INNER JOIN
tableD ON tableA.UserId = tableD.UserId
Where (tableA.UserId = @UserId) AND (tableB.UserId = @UserId) AND (tableC.UserId = @UserId) AND (tableD.UserId = @UserId)

View 3 RepliesI am very new to vb. I have to create a registration form based on the a complainant form and offender form. Complainant form fills out, take the complainant_ID and parse it to registration form to load. Now when the registration form loads, it has registration_Id and complainant_ID, fills out necessary info and add an offender from the offender form and pass back the offender_ID to the registration form..now on this registration form, we have registration_ID, complainant_ID, and offender_ID..complainant and offender can have more than one registration..
Table structures:
Complainant table(complaint_ID, last, first)
Offender table(offender_ID, last, first)
Registration table(registration_ID, complainant_ID, offender_ID, type, desc)
What I have done so far:
Using separate dataset for each form. Complainant/Offender/Registration form load and save fine. But I do not know how to bind these Ids together so they stay in sync.. What I mean, when I add new complainant, take the complainant_Id, parse it to registration to create a new registration for that particular complainant, and also add an offender to that newly created registration, and pass offender_ID back to registration form. I am using visual studio 5 and sql express..

Using; - vb2008 Express, data on ACCESS 2003, objective; - to update a separate table not on the original query.From what i have gathered i need to add a second table adapter to make the changes to a related field in another table. Since i already have the 1st table adapter the second does not appear as easy as the second (dragn the data set over).
So i suppose i need to create the second table adapters programmatically? [URL]..I see that because they are not nested they need to each be declared.. right? If so that is where my issue lies. I'm having a problem with how to declare them both now that there must be two.
I would like to know how to select multiple records from a gridview, (ie checkboxes in itemtemplate) and process SQL statements on the records.

View 7 RepliesI am almost there but for some reason I don't find the answer to my issue. Here it goes. In my application I have a form which displays a data grid view with some info I get through XML from a web server. The data grid view have as first column a Check Box colum. The second column have the information I get into a variable (from cells), one by one, to pass it to the sub with the XML command.
What I want to do is to be able to select all the rows and send the cell info of the second row (only for the selected rows) to my sub which will execute once then send the second cell info and execute the sub and so on until all the loop is complete. Currently my code works only if I delete one row at a time (sending the XML code will delete the info in the web server and update the datagridview which in return will remove the item).

when the user clicks on the add button another form launches, which enables the user to add student info such as name, address, course, start date and end date, this information is then written to class when the ok button on that form is clicked, and then displays the data on the initial form in data grid. the user can add multiple entries and they are all displayed on the intial form and a the data grid is populatedwhen any of the rows in the displayed grid is selected, and the update button is clicked then the same form launches as the previous one and but this time its in the update mode and pre populates the form with the inital values.

I have a webpage with a form that is used to edit some object. This object contains a Collection of other objects defined like this: Public Overridable Property Employees As List(Of Employee)
On a form I can delete an employee, add a new one or modify existing one. When I click save new values are sent to the server. On a server I check if the user exists. If exists then I modify its values, if it does not exist then I add it. All employees that exist on the server and were not sent are marked as deleted (State changed to EntityState.Deleted). I try to use the following code (dbCollection = database entities, newCollection = collection sent from the form):
[Code]...
This code does not work, because changing to EntityState.Deleted removes the object from collection, and for each loop breaks, since the collection is modified...I know that I can overcome this problem by using a for loop or adding objects to delete to some other list first, but I hope maybe there is a pattern that would make my code nicer.
