"ReDim Preserve" will do this for you. For example:

Dim myArray() As Integer = {5, 10, 15}<br />
ReDim Preserve myArray(3)<br />
myArray(3) = 20

See this MSDN article for more information.

Hi,

In my new project(VS2005) i want to create a datagridview and in that view
a new datagridview!
But i don't know where to start

I know i have to use some sort of relationship with the dataset, but i don't know the rest!
I want to display a row With in front of the row a + (Like in Explorer)
which you can expand (-) and see for this new a new datagridview inside the other with the child
rows.
Example :

Row 1 --> Customer, name, ...
Row a --> orderid, item,...
Row b --> orderid, item,...
Row 2 --> customer, name, ...

Does anybody have an example or an article about this

Thanks
A.

How can i override readonly property of Text Box

Public Overrides Property [ReadOnly]() As Boolean -- this doesnt work it says it is not overridable.
Is there any other method except controlling keypress,keyup,keydown events?

Override it to do what exactly? Change the visual look of readonly fields maybe?

If a DataTable is bound to your grid you could use its DataRowChanging/Changed events to validate data.

Just create a new PrintDocument, set the page/printer settings and call Print(). You surely have to handle the PrintPage event (the same as in the preview dialog).
