Processing of marker lines, interception of events of insertion and deletion of rows

Processing events mark the rows in GroupEdit

To treat check\ uncheck in lines GroupEdit:

• To FlexGrid from GroupEdit.
• Subscribe to the event CellChanged:

 fg.CellChanged-=new RowColEventHandler(fg_CellChanged); 
 fg.CellChanged+=new RowColEventHandler(fg_CellChanged); 

• In the handler to check:

 private void fg_CellChanged(object sender, RowColEventArgs e)
{ 
C1.Win.C1FlexGrid.C1FlexGrid fg = (C1.Win.C1FlexGrid.C1FlexGrid)sender; 
if ((fg.GetData( e.Row,e.Col) is bool)&& (e.Col==1)) 
    { 
         if ((bool)fg.GetData( e.Row,e.Col))  {   MessageBox.Show("Checked!");    }  else   {   MessageBox.Show("UnChecked!");    } 
    }
}

Interception of events of insertion/removal of an object in GroupEditBase

To intercept events from the delete and add object and under certain conditions these events to cancel in GroupEditBase, you can use two ways:

1. You can control the delete button on the toolbar (show, hide)
2. FlexGrid there is an event before deleting, which allows you to return to cancel the deletion
