Passing comma "," to a report parameter using URL reporting

Question

I have a simple report, which contains a string parameter.  Everything work fine, except when I pass a string with "," in the parameter value.
I tryed the following url and both of them does not work, I also modify the report to display the pass-in prompt value and the string is cut off after the ","
Example 1:
http://.../crystalreportviewers115/viewrpt.aspx?id=42364&prompt0=ABC&apsauthtype=secEnterprise&apspassword=p1&apsuser=u1&viewer=actx
Output:
ABC shows up and the report run fine.
Example 2:
http://.../crystalreportviewers115/viewrpt.aspx?id=42364&prompt0=AB,C&apsauthtype=secEnterprise&apspassword=p1&apsuser=u1&viewer=actx
Output:
Only AB shows up and the report run with AB as the parameter's value.
Example 3:
http://.../crystalreportviewers115/viewrpt.aspx?id=42364&prompt0=AB%2CC&apsauthtype=secEnterprise&apspassword=p1&apsuser=u1&viewer=actx
Output:
Only AB shows up and the report run with AB as the parameter's value.
How do I pass the "," in the URL

Answer 1

Since you are using viewrpt.aspx (instead of opendocument), you would pass a comma using promptex instead of prompt
so an example url would be:
http://.../crystalreportviewers115/viewrpt.aspx?id=42364&promptex0="AB,C"&apsauthtype=secEnterprise&apspassword=p1&apsuser=u1&viewer=actx
