Hi !
I'm getting a System.ArgumentNullException while instanciating a form that contains a GridView. I made my own research to find out the issue and end up on this: (see attached files)
The stacktrace is refering to the line 488 of my form (see in attached files) which is in the InitializeComponent method.
The error is occuring randomly so I don't have any clue on this...
Thank you!

Hi,
I want to basically have a completely unbound grid with some merged cells in row 0.
So, if I had 3 rows with 3 cols, I would want (Where A1, B1 and C1 etc. represent data):
Row 1: A1, B1 Merged with C1
Row 2: A2, B2, C2
Row 3: A3, B3, C3
And a have a single row on the column headers.
Can someone kindly show me the code for this?
Thanks ... Ed

I am tracking if document is modified by user so that I can append the text "(modified)" to the form's title, and also to prompt the user to save the modified document. My code also changes the document, but this is not a modification that the user should be concerned with. TextChanged event is alas raised in both cases. So I introduced a flag that means "ignore TextChanged event once". If in event handler the flag is set then just reset it. Otherwise update the form's title.
And now I've added default footer with code, in the same place where all other code changes to the document are made. This causes two events to fire, instead of just one. And now my document is marked as modified from the start. I could change the meaning of the introduced flag to mean "ignore TextChanged event twice", but that now just feels like a hack. Is there a "proper" way to track user's changes and not track changes from the code?

hi expers:
when i filtered the gridrows,i dont know the count of the filtered rows.
by the way,i use paged gridview,and i only know how many pages and pagesize
the property 'Childrows' always gives the pagesize of the gridview .
if if count the rows while filtering(the event CustomFiltering). the counts some times go wrong.
best wishes

Hi,
I'm trying to allow additional data on my chart to be panned through via the arrow keys but it appears that keydown and keypress events aren't firing for the cursor keys. Keyup DOES fire on arrow keys at least, but I'd much rather have it happen on keydown. Is there a reason for this behaviour or a workaround/setting I've not noticed?
Thanks
