- or - If you want to find more than one record, use the Find Rows method. The following example shows how to return the index of the found row based on the value in a text box control: data View1. In code, use an index value to identify the record to update, and then set the column value by referencing its name.

In that, you will have your code that paints your screen (this causes your screen to be painted correctly when needed). I have a custom method that prints a Data View of the Data Table out on the screen.

The problem I'm having is, i need to call the custom method whenever the Data Table is changed. this is not a standard binding problem, since I need to call a custom method to paint the items on the screen.

I understand what you're saying about the paint methods, but the populate Menu method goes through the view and adds each item to my customised menu. Then, that control should have an event handler for the Paint event, or an override of the On Paint method.

Hi Nicholas, How can I determine when the Data Table is changed ?That way I can right the change to the DB and update the Data View without having to dip the DB every time and essentially avoid reloading a 1000 rows of data because I changed one. Thanks Tim You can use the Get Changes method to create a new Data Set that can be sent into a Data Adapter to perform your update on only the changed rows.Since you've already made the change to the original dataset, you don't need to return everything back from the database.To populate this menu, I iterate through the Data Table by: foreach (Data Row View row in view) The trouble I'm experiencing, is when I add change the datatable in any way, I need to update my ownerdrawnlist control.I'm using a view to sort the datatable alphabetically, and then I want to iterate through the view populating my table.
