View 1 RepliesUpdating The Current Record On The DataGridView?
Jun 22, 2011Visual basic 2010. I am having a problem with updating on a DataGridView that has me confused.
I have a DataGridView on the first tab page that is displaying data in a DataTable.
On the second tab I am updating the current record on the DataGridView.
The text fields on the second tab are bound to the DataTable in the following manner
rnameTxt.DataBindings.Add(New Binding("Text", TableData, "rname", True))
When I move to the second tab the correct data appears in the text fields.
When I modify a field on the second tab the modified data appears in the DataGridView, on the first tab page. But when I check for changes in the DataTable in the following manner
Dim ModifiedRows As DataTable = TableData.GetChanges() I do not see the modified row - i.e. ModifiedRows = Nothing? Why is the modification not being identified???

Setting Currentcell In A Datagridview?
Oct 2, 2011I am writing an program with multiple tabs. I have a class that reads a database and offers that data and other calculated data as a collection (the class is cEngines containing engine rows). I have another class which is a row (item from the list) of the collection (the class is RowData which is an engine). One of the tabs in the program contains a datagridview which is bound to the cEngines class and another tab contains controls bound to the RowData class. Both tabs have a mechanism for selecting/changing the RowData so that both tabs are syncronised. All of this works.
The RowData class has validation - both simple value checking, or more complicated checking based on other items in the class. A validation failure raises an event.

DB/Reporting :: Bind These Textboxes With Current Datagridview Position?
Apr 10, 2008On one of my forms i have a datagridview binded to an Access database. It displays only first and last names of my customers in a datagridview.What i want to do now is, when i double-click on one of the customers another form will open and display details for this customer (detailed view - textboxes).
What i have accomplished so far is that when i double-click on a customer in datagridview a form opens with details (linked to the same binding source as datagridview). But the problem is that it always opens the first record even if i dobule-click second or third in datagridview.I don't know how to bind these textboxes with current datagridview position?
