Hi guys,

When creating SSRS report by using RDP, in my report design there is one parameter called : /<name of the report>_DynamicParameter/

How to utilize it so we can print it in our report ?

If I directly print this, it will only give me somekind of number which I guess it is the recid.

In my RDP, I'm using this,Query(), and if I put the query to string variable I can see the query, should I just look at the string and parse it when they found /where/ select. But what if someone join the datasource during runtime, I think my code will break.

So may I know whether there is better way of doing it, to utilize the /<name of the report>_DynamicParameter/, instead of write code in RDP class to /manually/ get the range ? I mean, when run time, we don't either whether the user will join to other table or not.

Thanks,

Trying to parse the query string wouldn't be a good approach. There is a much easier way: utilize Query* classes, e.g. you can list data sources in a query, get ranges and their values etc., all as normal object-oriented code. Printing dynamic parameters will give you some idea. Note that the blog post covers query ranges, if you need query filters, you'll find code in a comment below the article.

Instead of parsing the parameter value in your RDP code, use expressions directly within your report to access and format the parameter.
You can access the dynamic parameter using the Parameters! collection and its name, for example: Parameters!<_report_name>_DynamicParameter.Value.
Within the expression, you can then use various functions like Format() or ToString() to convert the raw value into a more user-friendly format for printing.

No, DynamicParameter.Value, won't give you anything useful.
