I am using VB.Net 2003 with an Access 2000 database. The program contains three options for the content of a DataGrid, each from a different table. I have finished programming the DataGrid which loads as the default when the program starts.When I run the program the DataDrid appears, but it is empty, except for a small box with a "+" in it. I click the + and the table name appears, I click the table name and the DataGrid is populated exactly as I wanted it.
What I am trying to do basically is open an access query in a datagrid view and then be able to make changes to the datagrid and then save it back to the database.When I try to save:
I have a materials library that I am adding into a database, the library has a number of columns, the one I am concerened with here is the Item Code column.
All Item codes start with 'M' and then have an integer after them (M1, M2, M3.....M9999 etc) What I want to do is to auto generate the next available item code when a new line is added.
The next available code should be based on the last value in the 'Item Code' Datagrid View column but I don't know how to do this.
I have tried getting the next available code from the database but this doesnt work as I want it to. [code...]
I have been coding in Visual Basic with Excel for a while and am now getting into using databases within the code. I have been looking everywhere trying to find how one can code for the datagrid width. I have figured out the individual columns but I want to code for the entire grid width. I am trying to code the datagrid to be the exact total of all of the columns eliminating the horizontal scrollbar and then next I will eliminate the vertical scrollbar for any account that has less than five records.
1. how could I control the colum size for every field in the grid?
2. How do I clear the grid? Have done i SQL filer that shows the resault in the grid, but when I select i new one it does add on that query. datagrid.clear() work one time, then I got an Error and this does not work
dg1.DataBindings.Clear() dg1.Update()
So do you have some examples in data in datagrid or tutorial links on it.
of code to transfer from a datagridview to Excel.I used to convert to adodb and do it that way, but I'm trying to get away from activex.o... I made the following method: It takes about 45 seconds to run. It also locks out my application's gui thread for that time period and it would be nice to also run this as a seperate thread...Can this go any faster? The background colors are important to the person I'm doing this for
Public Shared Sub toExcel(ByRef DGV As DataGridView, ByVal Name As String, ByVal lastSaved As String) Dim rowNo1 As Integer
Been trying to get my code for a datagrid with my owntemplates to work but I'm about fed up with it now butI still want the control over what I can do with the data.I'll give you all the code I've been working with.I would like to keep the concept of what I have been doingthe same if that makes any sense, I like just using classesand code behind.If I turn AutoGenerateColumns to false I do fill the grid with the data.Otherwise I'm not filling it with the data, just the text from the labels.Also the TextBox doesn't show either.

I'm working in VB.Net w/ WPF and I need to create a DataGrid at run-time (in the code-behind) with the text in each grid cell able to wrap. I've found a lot of examples showing how to do this in the XML but I can't find anything explaining how this is done in the code-behind. I'm stuck trying to figure out how the DataGridTemplateColumn, CellTemplate, and DataTemplate all work together.
I am trying to rewrite some code and I am trying to determine if I am writing it correctly. My goal is to make sure that the old code and my new code produce the same results(i.e. are logically equivalent). Are the 2 code blocks below equivalent?

My question is how can I create an event that would catch an enter key when I am editing it. Like I would type a note and hit enter key when I finish. Because columns of the datagrid does not have events like other controls or datagrid itself. What I need is something like this:
Private Sub ColumnNote_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles ColumnNote.KeyPress End Sub
