i try to dispose controls in split container using this code.
foreach (Control c in splitContainerMain.Panel2.Controls)
{
c.Dispose();
}
but problem is split container has contains two controls and get count is two. but i try to dispose using this code then one control is dispose successfully but second control can not be disposed.
I don't think that you should be using foreach in this case since the controls collection could be shrinking as items are disposed.
I think you would be much better off as follows:
for (int nI = splitContainerMain.Panel2.Controls.Count - 1; nI >= 0; nI--)
{
splitContainerMain.Panel2.Controls[nI].Dispose();
}
