I would like to bind different queries for a long set of columns in datagridview that has been set already during the formload, e.g:

I am struggling to understand fully, I need to bind data from an access database to a datagridview. (the DB simply holds a list of product with their stock code, description etc) I need to bind this datagridview to a products collection without using a dataset to bind to the datagridview. I really don't understand this fully.

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
How can we databind a datagridview to some of the My.Settings (user scoped) properties so the user can edit the values? This must be to a datagridview. I know we can bind to My.Settings in a form with textboxes and so on, but in this case we just want it as list of editable strings in a datagridview.
Of course some My.Settings entries can have different datatypes which complicates matters but generally we're only working with strings and booleans. Also, let's assume the user understands that he must enter the string "true" to set a boolean to true. No checkbox column needed. Here's what we are using (and it works), just looking for a better, leaner way: [Code]
I have a datagridview who's datasource is a BindingSource. The problem that I need to resolve is that the DGV has 6 columns, 5 of which come from the same database table, while the other column comes from another database table. Is there anyway of configuring the BindingSource that will make it contain all 6 columns?
The same grid in Part 1 works in the way that when a user selects a row, textboxes and comboboxes are populated with the DGV Row of data in order for the data to be modified. When the user makes any changes, this modified data needs to update the DGV row or BindingSource. How do I associate the changed values back to the BindingSource or the DGV?

I have combobox in a form. The combobox is bound to a table and displays the list of values as expected. What I want to do is also bind the combox to another field in a different table similar to the way the datagridview with combobox works. That is the dgv is bound to the combobox column but the dgv's bound value sets/reflects the value selected by the combobox. I can't figure out if this is possible with a standalone combobox.

know it is possible to have bounded and unbounded columns in a datagridview.Is it also possible to have bounded and unbounded rows?I knows its unorthodox, but I want to have two rows in my datagrid per item in my object list One row is bounded to the properties of each item; below that I want an unboundedrow of checkboxes for each property But since when binding the datagridview sets the rowcount equal to the list count, I'm not sure its possible.

I'd like to partition my search results (which is in a DataTable) into groups of say 100 so the user navigates through them a chunk at a time.I thought I could bind an array of DataRows to a DataGridView as the DataSource but it just does not work. This is the code I tried
