  Hi akhterr,

  It seems you have posted twice for this subject, and have marked an answer:https://forums.asp.net/t/2158515.aspx.

  I have tested your current behind code along with the front code you provided earlier in above thread. After i removed the comments in your code, everything worked well.

  

  Is there a new problem you are facing with? Please tell.

  Best Regard,

  Yang Shen
