VB.Net: Refresh ListView and DataGridView

Hi Experts,

In a ListView or in DataGridView I fill data from the database, and the query may contain about a few hundred to thousands of records.

But if I make any changes to the values in the ListView or in the DataGridView (the changes are only to a few rows or for a few cells) and to view the changes I always refill the controls by re-querying, which is really inefficient.

Is there any method that I could use to only refresh a particular column or rows or cells, or a collection of them rather than refilling them in the ListView or in the DataGridView.

Thanks in advance.

Sure,

   You have to deal with the CellEndEdit method and each time a cell is changed do a look in the table for the specific index (Id) and if the value is diferent just update thtat value in the listview or datagrid.

Hope this helps

So you have two controls and you make changes in one and want to see the change reflected in another?

Hi CodeCruiser,

I am using a Single datagridview and i make changes to certain cells in the gridview and when i click the save button, is it possible the edited cell to be updated to the database or to the dataset.

Thanks in advance.
