How to disable a particular row in the GridView

Example Comments

This seems like a bug in RowStateHelper.cs:
public GridView GridView
{
     set { UnSubscribeEvents(value); _GridView = value; SubscribeEvents(value); }
}

Shouldn't it be this:
public GridView GridView
{
     set { UnSubscribeEvents(_GridView); _GridView = value; SubscribeEvents(value); }
}
private void UnSubscribeEvents(GridView view)
{
     if (view != null)
     {
          view.RowCellStyle -= view_RowCellStyle;
          view.ShowingEditor -= view_ShowingEditor;
     }
}

I have a grid and it's showing a list of invoices from the table. If the invoice has been posted then I want the row disabled so a user can't edit it.

I am using vb.net. Can you tell me the steps how to do it? I am new to this grid control.

Thanks

This does not handle the situation where rows above a disabled row are deleted. Say I disable rows 5 thru 10. I can delete the rows above row 5 (rows 1 thru 4). And as I do that, what were rows 5 thu 10 now scroll up and I can now edit them or even delete them.

Yes, you are right, this example doesn't handle this situation. In this example, we just show the main idea how to accomplish this task. To simplify our code, we use a row datasource index to identify rows. If you want to add/delete rows and save their disabled state, I suggest that you use a key field value to identify rows. In this case, this approach will work correctly.
