Thanks in advance for any assistance.

What event would I use to grab the GridRowInfo when the navigates to a another row? I'm working with the RowsChanged event and it's firing after -each- change to the row when evaluating the NotifyCollectionChangedAction.ItemChanged enum.

Essentially, what I need to do, is if any value in the row changes, I need to get the row and update the database. If I use the RowsChanged event, I potentially would be updating the same record over and over if multiple values are changed for the same record.

Do I need to use a combination of events?
1. RowsChanged - store an instance of the GridViewRow to a local variable
 then
2. RowValidated - commit row information to database?

Is there a more direct way to do what I need to do?

Thanks,

Morgan

Hi Morgan,

You need to subscribe only to the CellValueChanged event, where you can perform the saving logic:

this.radGridView1.CellValueChanged += new GridViewCellEventHandler(radGridView1_CellValueChanged);


private void radGridView1_CellValueChanged(object sender, GridViewCellEventArgs e)
{
    GridViewDataRowInfo row = e.Row as GridViewDataRowInfo;
    GridViewDataColumn col = e.Column as GridViewDataColumn;
 
    // TO DO Your Save operation
}

I hope this helps.

Best wishes,
