Bind An IEnumarable Collection To A Datagrid (items Of Variable Contents)?
Aug 11, 2011While working with an excel file (.xlsx), the data I get from it is an IEnumerable(of Dictionary). When I bind this to my datagrid, I get the problem that I only see 2 columnsI've been tracing this problem and discovered that in the first row in the excel, there are only 2 values (cell C and D). I think the binding to datagrid looks at this first row to create its headers. This results in my datagrid only showing columns C and D.

.net - OleDbDataAdapter Fill Datable?
Apr 30, 2012filling an OleDbDataAdapter.I have:
Dim cmd As OleDbCommand = New OleDbCommand(myQuery), myConnection)
Dim da As OleDbDataAdapter = New OleDbDataAdapter()
Dim dtDonnees As DataTable = New DataTable()
da.Fill(dtDonnees)
Filling takes too much time.For 20 lines it takes 20 seconds.And for 130 000 it takes a little more (but not 130 000 sec).But 20 seconds is too much anyway.
Question part 2: can I skip fill?I mean, after filling the datatable, I do a for each row of datatable and cast into an entities:
Dim returnList As New List(Of myObject)(dtDonnees.Rows.Count)
For Each rowDonnee As DataRow In dtDonnees.Rows
returnList.Add(New myObject(rowDonnee))'set every data of the row into my new object
Next
Can I pass each row of OleDbDataAdapter?

DataGridView To Bind Or Not To Bind?
Sep 2, 2010I'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
