Please give me any suggestion how to write not null conditions in vb.net?

Solution

You can do it a few ways, you could do:

Value <> Nothing

Or

If Not String.IsNullOrEmpty(JobEventAllDetailsSortnew.Item(value).EventText())

End If

To name a couple of ways.

You should use Value IsNot Nothing to check for not being Nothing.
