OnClientClick requires 2 Clicks how to solve this?

[rprateek]

Protected Sub cmdOk_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles cmdOk.Click
Dim str As String = ""
str = ConcatAirCode()
cmdOk.OnClientClick = "Done('" & str & "','" & strTextId & "')"

End Sub

I did this in code behind because i need to pass two variables in my Js function Done. It works but requires two clicks as it is posting the page on the first click. Any one got the way around it.
