I've been programming for a while now and I have a Datagridview which is databound. It pulls up a list of my line items and that works fine. So I have:
OrderID, OrderType, OrderNumber, OrderDescription
Anyhow... these fields all come from the OrderDetails table. I have another table, AllOrders, where one OrderID can have multiple OrderNumbers.
What I need to do is:
1.) The OrderNumber column should be a dropdown list of all OrderNumbers from the AllOrders table where the OrderID matches.
2.) This column should also let users manually type in a value and it saves it to the list.
3.) When the user clicks a save button on the form I need to be able to reference the values from each row to save the selected value to the OrderDetails table.
I thought this would be something rather simple... and I've been pulling my hair out for days. Sometimes I can get the dropdown to load the OrderNumbers correctly, but I can't add one. I can get a ComboBox cell where I can add a value to the list, but I can't load the existing OrderNumbers, etc.

I have a Windows Forms DataGrid currently filled with text.What I want to do is have a ComboBox appear in a cell when the user enters it.After the user has chosen their item from the ComboBox list I want the ComboBox to be removed leaving just their selection as text in the DataGrid, when they leave the cell.

As part of a user interface I'm designing, I'd like the user to encounter the following: when the user wants to edit a value in a cell, the cell in the DataGridView is replaced by a DataGridViewComboBoxCell. This is working now, however, when the user enters the cell (edit cell) the edit cursor stays there, and the combobox won't show. When the user leaves the cell, the Combobox shows, and after again entering the cell and clicking on the combobox, the dropdown finally shows. So 6 clicks are necessary, and I'd like to reduce this to a maximum of two clicks.
Using VB.Net on Visual Studio 2008, with .net 3.5
This is my code:
Public Class Functions:
Public Sub ComboBox(ByVal source As System.Windows.Forms.BindingSource, ByVal MainView As System.Windows.Forms.DataGridView, ByVal valuemember As String, ByVal displaymember As String, ByVal row As Integer, ByVal column As Integer)
[Code]....

I am using vb.net 2010 and winforms and DataGridView. The DataGridView has a DataGridViewComboBox column. When I show the form with the DGV it shows this and empty grid but the column that contains the ComboBox shows the first item on the dropdown list. How can I have the ComboBox display nothing until it is clicked on and selected?

We have a lot of PDF documents and would like to save information filled in by the user in SQL database and then pre-populate the answers in multiple PDFs for printing. We'd also want user to digitally sign the pdf and store the signature in database. Ideally I'd like to create VB project with form that users would fill in and then information should "flow" into existing PDF. Then later I'd setup some reports based on user-filled information. We probably will purchase Adobe LifeCycle software to use with PDF.

I have created a function to create a string to populate a y axis with data:
Function talktosql() As Double
Dim ConnString As String = "Data Source=MARK-WORKMSSMLBIZ;Initial Catalog=Yahoo_data;Integrated Security=True"
Dim SQLString As String = "SELECT [RDSA.L] FROM yahoo_data.dbo.XLON"
Dim SqlDataAdapter1 As New SqlDataAdapter(SQLString, ConnString)
[code]....
so it should for example come out like this:
Dim yValues As Double() = {55.62, 45.54, 73.45, 9.73, 88.42, 45.9, 63.6, 85.1, 67.2, 23.6}
I cannot seem to get the data from the function into the right format to populate "yvalues".(the msgbox that I put in at the end in the first code renders the result "0")

I have a dropdownlist that I want to populate with a specific value and specific text. I'm not using a datasource but I am manually making a connection and retrieving data in code. How can I populate this dropdownlist? If I read the data with a datareader and increment an array I only get either the value or the text. This is what I have so far, but it is completely wrong:
//connection string etc goes here
Dbcmd2.CommandText = "select dept,deptname from table"
Dim dr As SqlClient.SqlDataReader[code]....
How can I get this to work without having to create a class object for Department? Is there anyway or should I create the class object?

<Visual Studio 2008 / VB.NET /SQL 2008>. I have a form that populates data when Load event occurs. The problem is it looks like a slow motion movie when the form is loaded since there some quite amount data is populated. This is happen because I put a coding to populate data on Form Load event. Is there anyway that I can prevent the slowing down of form load event? I guess best thing is load form completely and trigger populating data.

I am trying to populate a treeview with data from and xml document.
The loading of xml is no problem i have done that a million times over, the problem seems to be able to fill the treeview with content. My problem is this: I have a treeview with this in it:
-Race
|-HQ
|-TROOP
|-ETC...
now... the program loads all units from xml. so when it encounters for instance a unit with a "<class>" tag containing HQ, how do i make it put it in the HQ node? I cant make it put new nodes into existing ones, only into new ones....

I have a simple access database that a log record gets written to a few times an hour.
I'm trying to make a DataGridView that shows that data as it arrives.
My "Solution" is simple;
when a user clicks the view -> read from the database (fill the datatable) -> update the view.
Not what I dreamed of, but functional, if totally sub-optimal.
However, my "solution" is a dud, using fill draws every single record from the database, even if there are already 599 on screen.
Really, I just want fill the datatable once, and add new records as they arrive (or on click if needs be).
Bonus point if you can also explain another way (that isn't called so often) to hide the ID column, and change the header of column 1 (named DateTimeStamp) to TimeStamp.
Public Class FormMain
Shared dataAdapter As OleDbDataAdapter
Shared logTable As New DataTable("log")
