I am having problems adding a new row to a datagridview control in my form. I have a simple formwith a textbox, a button and a datagridview. When the user types in an item number and clicks on the button, the system will populate the datagridview with the relevant data from the database.All these works fine but, when the user tries to add another record, the first record added to the datagridview is cleared off the datagridview before the next record is displayed. I would like the datagridview to add all the records without clearing the screen. The datagridview is not bounded to the database.

I have a DataGridView bound to a datatable which comes from an SQL Server database.When the user edits a record my update statement changes the field datetimemodified to reflect the last date and time the record was edited (as stored procedure). The new value for datetimemodified is not brought into my DataGridView.
1) How do I refresh a DataGridView bound to a DataTable? Is there any way to refresh or resync only records that have changed instead of the entire DataTable? (Note: my update statement is working fine. I'm only wondering about refreshing the DataGridView.)
2) Would it be better to change the value of DateTimeModified on the client side so that I can avoid a refresh (assuming that this is the only reason I need to refresh the data)?
I have a form that contains a datagridview, which is working properly. I want the user to locate specific records that are displayed in the grid. To that end, I have a sub that uses the datatable select method to find rows within the defined record set:

As
String[code]......
As far as I know this is working, as no exception is thrown.Is it possible to have the grid display this record if it is found without having to rebuild the grid?
I am trying to find or search record from a datagridview so I could replace it with a new data from a textbox.

I just couldn't figure out how to datagridview works with if else statment.

View 4 RepliesVisual 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???
How can i get the postion of the pointer or record number from a datagridview when a user clicks on a cell in the datagrid.?
