Hi Mike,

Thanks for the quick response. So, do I need to check for the existence for the following:

this.popupPrintFax.Tools["btnPrintReq"].SharedProps.Enabled = false;
this.popupPrintFax.Tools["btnFaxReq"].SharedProps.Enabled = false;
this.popupPrintFax.Tools["btnPrintRes"].SharedProps.Enabled = false;
this.popupPrintFax.Tools["btnFaxRes"].SharedProps.Enabled = false; 

Could you give me a sample Psuedocode for this.

Hi Mike,

I saw the above thread. I am also getting the same error.  Please, find the error trace below. Need your help in this.
