If you already set up the query as SSRS parameter but the DynamicParameter didnot show out, then you can try the step by step in here.
1. Open your VS Project that where you design the report layout.
2. In the VS, Expand the Datasets > Your Dataset > Parameters, check there have DynamicsParameter or not.
3. If there did not have the dynamicparemeter, then you should check the query declaration in your DP class. And restore the report or delete original Dataset to recreate another one in VS until you can see the dyamicparameter.
4. After you check there have dynamicsparameter below the parameter, click your dataset, set the property "Dynamic Filters" to "True".
Now, try to run your Report Again. It should be show out the DynamicParameter now!
