DataGrid From VB6 To .NET?
Jun 10, 2008
I have converted a VB6 app to .NET using VB 2008 Express Edition, as recommended in the VS 2008. Actually just opened VBP project using this software and followed the wizard's instructions. The app has a form containing the ADODC control and AxMSDataGridLib.AxDataGrid. The DataSource property of the Grid is set to ADODC. (Actual data comes into UI from some DLL.)When I start debugging the converted app I immediately receive following error:Error -2147467259: [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified.Same error happens when I try to set the ADODC object to the DataGrid.DataSource programmatically (in run time).The VB6 version of same app runs without any problem.

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:
Me.BindingSource.EndEdit()
Me.TableAdapter.Update(DataSet)
It says that update is not a member of the tableadapter... Why is that?

I have a datagrid who's ItemsSource is a strongly typed IEnumerable object In this datagrid, I have a checkbox column, a price column, a part name column, and a 'total selling for' column. On checking the checkbox I need to update the total selling for column with the value in the price column. This part I have working, however, how can I get the checkbox to remain checked when this happens?
Private Sub UpdateSellFor(sender As System.Object, e As System.Windows.RoutedEventArgs)
Dim _CB As CheckBox = DirectCast(sender, CheckBox)
Dim _ID As Integer = _CB.Tag
Dim _PP = DirectCast(DG_PartsToSelect.CurrentItem, PartTyping).PartPrice

I have a datagrid which I am using LINQ to fill, I then add some custom columns and fill them in programmatically - if the users clicks on the column header to re-sort, all the data in the added columns disappears. I am obviously missing something very basic here but can't seem to see the forest for the trees. I also have a couple of other questions about how I am doing things:

I decided to rewrite my project. Hit another snag. How do I write the contents from a datagrid to a file and back into the datagrid again later? (Actually, I've done the writing ok - but for the life of me can't get the data back into a blank datagrid.
Here's what I done so far:

I have on my form two datagridviews that correspond to the same table. They are both databound. They have been created automatically through dragging them from the datasources windows.One is datagridview and the other datagridview1. When ever I navigate through a datagrid the corresponding row on the other grid changes as well. I do not want this. Also I want to be able to fill and use each datagrid indepentent from each other. To fill a datagridview on load I use this code
Me.AllServicesTableAdapter.workstation(Me.Database2DataSet.AllServices)This code does not let me choose which datagrid to fill.

I have a search form on that will be pulling search template queries from a table in the underlying (an Access db on a share). The search form has a calendar control for filtering by date range, a listbox containing the names of the search templates, a second listbox which lists the fields in the selected template, and then some controls which show/hide themselves depending on which field is selected so that the user can pick a field and enter it's unique criteria in the appropriate control for filtering. Below these controls is a DataGrid, which will obviously display the results.
The problem is how to dynamically "transform" this DataGrid to display the selected search template. These templates do not represent tables in the underlying; rather they represent preconstructed SQL queries (stored in a table) which are essentially SELECT queries with joins and no WHERE clause (so they are the results of multiple tables joined together by their keys).
To be honest, I'm having trouble even generating the LINQ queries to represent these template dynamically, but that's not as important, since I can manually translate the SQL queries into LINQ. This is definitely not the preferred method, as the whole point of putting these templates in a table, rather than code, was to allow for future additions without rebuilding/redistributing the application interface.

what are the differences between the WPF Datagrid included in the .NET Framework 4.0 versus the Datagrid included in the out-of-band WPF Toolkit? I understand that the toolkit version was released first, and targets the .NET Framework 3.5 SP1.
I needed a WPF datagrid quick and have utilized the toolkit version in my applications. I'm considering moving the application to .NET 4.0 and am wondering what the pros/cons will be in changing out my existing datagrids for the new ones.

I am just trying to put an item into a datagrid from another datagrid.
So I got code like this which takes the right item but puts it into the wrong place. It is suppose to put it into Rows(0).Cells.Item(3) but it puts it into item(2) as it caunts from 0 to 3. If i try to put it into Rows(0).Cells.Item(4) I get an error - indexOutofRange.
DataGridCLI.Rows(0).Cells.Item(3).Value = datagridorder.Rows(0).Cells.Item(2).Value

I have a checkbox in a datagrid in my form, the user can only select one checkbox at a time, if more than one is selected the other checkbox will be unselected leaving only one selected. This part works okay, however if I click on another combo box or datagrid on the form it forces the selection to be removed from my checkbox, I can't figure out what is causing this, has anyone had any similiar problems??

I have a SP that is building a table and the results from that table on the fly. So when I apply it to a datgrid, there are no columns to select, because they won't be created until the program is running.
Is there a way to display the data after the program is running?
