Hi Bikram,
I don't know the settings too..
Try doing it programmatically, by adding new line after a certain character length reached. in Vb.net I used vbcrlf
lets say I have "this is a sample static text" see codes below.
Dim strText As String = "this is a sample static text"
Dim finalText As String = ""
Dim maxLen As Integer = 20
Dim cntLen As Integer = 0
For s = 1 To Len(strText)
finalText = finalText & Mid(strText, s, 1)
If cntLen >= maxLen Then
If Mid(strText, s, 1) = " " Then
cntLen = 0
finalText = finalText & vbCrLf
End If
End If
cntLen = cntLen + 1
Next
Label1.Text = finalText
Good luck
