DB - Refreshing data in DataGrid
Posted on 2002-03-19
Hello,
I change a certain field in my MS-Access data-base from the program. Then I click on my "Show Query" button. It shows a new form with DataGrid (which is connected to Data-Envirement). However the data I see is old (not updated). Only if I restart the program I see the changes. How can I refresh the query (I thing I should update a command in the Data-Envirement but I don't know how).
Please check your suggestion before sending it.
Once I get a working answer, I will accept it.
Thanks in advance.
Slava.

Unfortunately, the Refresh method doesn't work when the control's DataSource is a DataEnvironment. Instead, to show the updated recordset changes, first update the DataEnvironment's recordset, then rebind the DataGrid to the DataEnvironment. So, if you have a Refresh button, it's click event might look like this:
DataEnvironment1.rsCommand
Set DataGrid1.DataSource = DataEnvironment1
Now, when you click the Refresh button, the code rebinds the DataEnvironment to the DataGrid and refills the control with the refreshed data.
DataEnvironment1.rsCommand
Set DataGrid1.DataSource = DataEnvironment1
Now, when you click the Refresh button, the code rebinds the DataEnvironment to the DataGrid and refills the control with the refreshed data.
does this answer yor question ?

The DataGrid control is a great way to display multiple data rows in a table-like format. Unfortunately, the control is also plagued with bugs. Some have been fixed by Service Patch 3, but some haven't. For instance, if you connect the DataGrid to a DataEnvironment, then make changes to the underlying recordset and refresh the DataGrid with the Refresh method, the control still doesn't reflect the changes.
