I have a form called studentForm which has a studentCombobox, studentTextbox and a studentDatagridView
In the constructor of the studentForm I need to bind studentCombobox to the StudentbindingSource of the main form and to bind studentDataGridView to appropriate binding source in the mainForm.So that this datagrid view displays all the bookings for the studentID currently selected in studentComboBox
studentComboBox.DataSource = MainForm.StudentBindingSource
studentComboBox.DisplayMember = "StudentID"
studentDataGridView.DataSource = MainForm.StudentDataSet
studentDataGridView.DataMember = "Names "
This is the code I wrote in the constructor

I have a combobox on a form. It works but I want to filter it with a constant value. I don't want to change the query in the dataset because that would affect other programs. So I click on the little arrow on the combobox in the form design view and then click on Add Query and make my new query which I preview and it's okay. The problem is I can't find any way to make the combobox reference the new query. In the properties for the combobox the Data Source is just the binding source. How do I specify a specific query?

I have 2 tables:tblcode and tbltransaction tblCode with 2 fields:Code and Description with data like
Code Description
A test1
B test2
C test3
and tbltransaction with 4 fields:transactionID,UniqueID,Code,Value with data liketransactionID and UniqueID are the primary keys)
transactionID UniqueID Code Value
120 1 A 0
120 1 B 1
I want to write a query that outputs:
transactionID UniqueID test1 test2 test3
120 1 0 1 0
so because tblcode has 3 fields I have 3 columns which are test1, test2 and test3(the descriptions of Code A,B and C) i tried to use pivots but it didn't work for me since I don't know in advance the number of rows in tblcode?

I want to Bind a BindingNavigator to a table using OLEDB or any other method (excluding the automatic stuff for increased complexity of my CW). I bound the Data Grid to the data using the following code
Try
Dim DA As OleDb.OleDbDataAdapter = New OleDb.OleDbDataAdapter("SELECT Question.Question_ID, Question.Question_no, Question.Question FROM Question INNER JOIN Quiz ON Quiz.Quiz_ID = Question.Quiz_ID WHERE Question.Quiz_ID =" & GetID(combQuiz_Title.SelectedItem), myConnection.GetConnection)
[code]....
Then I created my own delete and save commands. But I dont how to do the same using BindingNavigator

I would like to bind a DataGridView to the results of a query generated as text at runtime.How can I send a query as text to Microsoft Access and bind the results to the DataGridView?When the user clicks the button (ok_btn), I want the contents of the textbox (query_txt.Text) sent to Microsoft Access, then I want the results of the query shown in my DataGridView (results_grid).
Simple one-row queries are fine for now: (SELECT "a";, SELECT "a", "b";, SELECT now();)
NOTE: C# accepted, VB.NET preferred

I have the following overloaded functions I use to fill a combobox.The first function works the way I want it to except for the fact that I pass a combobox in. I wanted to create a simpler function, thus my second attempt.For some reason the line:tempCombobox.DataSource = tempTable does not bind the data table to the tempCombobox. What am I doing wrong?

I am trying to bind data from a text box on my form to a field in my database table. First of all I have created a DataSet, BindingSource and Table Adapter in the forms Design view, but I am having from there. Under the properties of each text box I have set the DataBindings (Text) to the field in the table under the forms instance and DataSet rather than the Projects Data Sources. I am very rusty at Visual Studio 2005 and that is all I have to work with.

So in this gridview, there is a column for status and I want to have a drop down list with Pass, Pending, Fail appear when the edit button is clicked. These values are already in a table, so I need to somehow bind from this table to each ddl for every row.Here is the column from the gridview. As you can see, I would like to just have a label showing when not in edit mode, and a ddl when the edit button is pressed
<asp:TemplateField HeaderText="During Production Status" SortExpression="DuringProductionStatus">
<EditItemTemplate>

First I have 2 tables, for example Customer and Orders, and in the database there is a foreign key relation between both. For clarity Orders have a foreign key field to the primary key of Customers, thus Customer is the parent and Orders is the child table of the relation. My application is a Windows Form application, and I add a dataset to the project, in which I drop the 2 tables, and the relations between the 2 tables is automatic added. Now I will om a form loop through the Orders table (witch is the Child table) and show in a textbox some fields of the Orders table and also the Name field of the related record of the customers table. Regarding binding a textbox fo a Orders field I do it this way,
Dim myDs As New DataSet1
Dim myAdpCustomer As New DataSet1TableAdapters.CustomerTableAdapter
Dim myAdpOrders As New DataSet1TableAdapters.OrdersTableAdapter
myAdpCustomer.Fill(myDs.Customers)
myAdpOrders.Fill(myDs.Orders)
Dim myBindingSource As New BindingSource
myBindingSource.DataSource = myDs.Orders
myBindingNavigator.BindingSource = myBindingSource
TextBox1.DataBindings.Add("Text", myBindingSource, myDs.Orders.OrderIDColumn.ColumnName)
But now I can't find how to bind a textbox to a field of the Customers table witch is the Parent table of the relation.

I'm currently developing an application with a reasonably complex DataGridView that allows the user to build the lines of a sales document: Quantitiy, Description, Price, etc with some additional fields to help calculate price based on cost or discount i'm sure you get the jist - all this means we're not just diplaying data but adding and manipulating it - It also means there's mainly decimal fields, nit just simple text fields
Now, i'm new to VB.net, so i've perhaps done things a bit backwards during my learning curve, namely designing and coding my DGV before creating the underlying database table and binding to it - so as i'm sure you can image there's a bit recoding to do to allow for the fact that it's now bound to a datasource.
I'd got the DGV working just how a wanted it to, but now that i've bound it to a datasource i'm hiting multiple problems with: Formating the appearance of figures in the DGV Problems with blank fields while enering data (before the i try to save the data back to the database) How the DGV is functioning - it seems to behave differently when adding lines to a new sales document than it does when adding lines to an existing sales document
And given that when saving edits to an existing line i need to provide a valid update command i'm begining to think that it might be easier to scrap the databinding altogether and just Select, Add and Edit the database with code rather than binding the DGV in the IDE
I've read various threads about avoiding databinding due to it's limitations, but i've also read that it's far better in later versions of Visual Studio and .net. and i'm using VS2010
I'd just like some advise as to whether my gut feeling is right or whether i should persevere with databinding the DGV. i've noticed some quirks of databinding while working with other controls such as text and combo boxes, but i've overcome these and the result seems to be easier than coding the data transfer manually.
But i'm really struggling with databinding the DGV and the fact that i'm dtatbinding to a seperate table to the rest of the controls is leaning me away from databinding
