As you can see, when i close one of my Winform(on the tabpage), i have to send back data and modify the tab_index. I am able to close both Winform and tabpage, but struggling how to send the data back. I know how to send back data from childForm to parentForm, but the situation here is little different.
You could use a global property on the parent that all controls have access to
new
, it instantiates a new reference. You need to do something like tabControl1.Parent.tab_index--

But it doesn't work, the tab_index is not the right value, its 0 every time before i close the form - qwr qwr 2012-04-04 01:45
