I have two data tables. the second related to the first. Using a datagridview for the first table I am able to enter and save data ok. if I run the code twice in a row the data is still there. When I edit the data in the related table in it's own datagirdview the data is there and displays correctly, but on running the code a second time the related data is lost. In both cellendedit events I am using
Me.table.Update(Me.FigsDataSet.table)
Me.Validate()
I am trying to click on certain rows in a datagridview and have the information in the rows sent to a textbox. It does not append each row to the textbox though, which is what I want it to do. it just replaces it with the row I click on. What's wrong with my code. I have tried cell click too.

Is there something like VBA's ScreenUpdating=Off in VB.Net? I mean, I want to manage the underlying data and wish it would not reflect on the screen until the end.
View 7 RepliesI am retrieving data from my database using a TableAdapter. I was wondering if there is some way I can tell (or be informed) that the data has changed and I therefore need to do another Fill? That way I can just Fill on demand rather than every time the user requests to see the information and I am forced to do a Fill before showing the data because I don't know if is current or not. For the record I am using an ODBC connection string to access a Pervasive PSQL database
EDIT I was thinking I could check the last write time of the MKD file to check if this has changed but this doesn't seem to be reliable as it is not written to until the connection is closed. Does anyone know the circumstances when this is written?
I have an object databound to a WinForm. One property, BOLNumber is bound to a textbox on the form. When you change the value in the form, the underlying BOLNumber property is changed. But the property setter does some "formatting" to the value. I want to BOLNumber textbox to reflect the changes to the value made in the property setter immediately upon the textbox losing focus. I tried implementing the INotifyPropertyChanged interface, but I am either doing something wrong or misunderstanding something it would seem. How do I get the databound control to reflect the changes to the underlying data source?
Public Event PropertyChanged As PropertyChangedEventHandler _
Implements INotifyPropertyChanged.PropertyChanged
Public Property BOLNumber As String

Is it possible to have a Textbox on a form that when the user inputs data, ( during Runtime )that data remains in the Textbox for good and the Textbox then becomes read only ? Is it also possible to make it so that the CD with the programme on, is in the PC when the programme is being used. Perhaps writing the Textbox data back onto the CD ?

which is supposed to get all the data from my table and set it as the datasource of a DataGridView. You can see where I put in two msgbox's to view how many columns are in the DGV before and after the "update". The first count gives me 22, which is the correct number. After the .DataSource and .DataMember lines are ran, the count jumps to 41 and I have no clue why. All I want to do is clear a dataset, fill it with the new data and set it as the data source of a datagridview. It appears the info is being saved to the table correctly too.

View 1 RepliesI found a sample of how to display data from a table in to a datagrid using VB.
con.Open()
Dim reader As SqlDataReader = _
cmd.ExecuteReader()
DataGrid1.DataSource = (reader.GetSchemaTable())
reader.Close()
But this just displays the details of the table columns. For example row 1 has details about usrID, row 2 usrTel ect rather than the actual data of the table.
