Passing UserControl as Function/Method Parameter
|

Hi All,
I'm populating a tab control with tab pages dynamically and in turn, each tab page that is created has to have a specific user control added to it.
Now I've managed to do this, no problem, but I'm working on a function that I can call from each menu item I click, to do the job, instead of copying and pasting the same code over and over and over again, only to change one line. So this is what I've got so far:... more »

DataView question
|
| |
I have defined a DataView on a DataTable and set Sort and RowFilter
properties so index is built for the view.
If I add/delete rows from the DataTable, does the DataView index get
rebuilt after each add/delete?
If so, how much does that affect performance?
