How to group parameter values in SSRS - reporting-services

I currently have a few parameters set up in my SSRS report, but one is kinda giving me a bit of a headache.
I currently have a parameter called PARAM_ONE which is populated by a Dataset that I have. The value is populated the Id field of my Dataset and the label is the TextValue field of my Dataset.
I have another parameter called PARAM_TWO which is populated by a Dataset that is filtered based off of what is selected from PARAM_ONE. Again the Parameter value is populated by the Id field of this Dataset and the label is the TextValue.
My issue is that this Parameter shows duplicate fields because of the way that the data is set up. There are multiple values that go to the corresponding data I am trying to display. I would like to set it up to group all of my PARAM_TWO data that way duplicates are not showing, but I still need that first dataset relationship to map the data.
I hope this makes sense, and someone can help. If I am not making sense and need to clear anything up I would be more than happy to, just let me know.

I was able to figure out the solution to my issue thanks to the help of #user3340627.
In my dataset I created a query that looked something like this:
SELECT DISTINCT Id, TextValue FROM MyTable
WHERE SecondId = #PARAM_One
This created a parameter in the Parameters tab called #PARAM_ONE. I was then able to map my report parameter to the query parameter and run it with no issues.

SSRS New page per selected Parameter

I have a report which uses 3 datasets and on the report a am using Multiple Tables and Textboxes and expressions. When I run the report I have to select a Parameter which in this example is 'City'.
I want a new page for each City (parameter) , I have read to use page breaks and grouping but I selected a List from the toolbox and put that on top of my report, selected 2 'Cities' and expected it to return 2 pages but it returned 49 pages (majority blank)
I want a separate page per city how can I achieve this?
Thanks
If I understand you correctly (it difficult to be sure if you don't post your current design) then you would be better using subreports.
I'm assuming Cities are in a table in your database and each have a unique ID. If you only have the names then you can use CityName inplace of CityID and it will still work.
Create a new report.
Create new dataset (say dsSelectedCities and the set dataset query to something like ...
SELECT CityID, CityName FROM myCitiesTable WHERE CityID IN (#CityParameter)
This will automatically generate a report parameter called #CityParameter. Set the available values etc just the way you did in your original report, so if you need to add another dataset for this then do so. In this example I've assumed labels will be CityName and Values will be CityID. Whatever goes into the Values is what will be passed to our subreport.
Now add a table to you report, it only needs to be one column wide and one row long so just remove any other rows and columns just make sure you leave the detail row and not the header.
Set the dataset for the table to be dsSelectedCities
Make this remaining cell with wide enough to accommodate your subreport (which will be the report you originally wrote).
In the cell, insert a subreport
Set the subreport properties to point to your original report and set the parameter to the CityID field.
This table will act as a loop, for each record found in dsSelectedCities it will give us one row. As each row will have a single CityID we are passing that to the subreport, the subreport in turn just shows one City.
Set the page break option on the details group to break between instances.
You will probably have to modify your original report to accept a single CityID, it depends on how it was designed but hopefully this should get you going.
If this is unclear then post your current report design including all the details about parameters and I'll update the answer.

Display selected values of multi-value parameter in tablix rows

I am designing a report for SSRS. I want the user requesting the report to be able to specify, when they generate the report, from a pre-defined selection some values which should be displayed in a tablix on the report.
I have therefore created a multi-value parameter and populated the Available Values with the options I want the user to be able to select from, and, as expected, when the report is generated the user is able to select one or more of these values.
However, what I now want to do is include a tablix in the report, and display a row for every value in the multi-value parameter that the user selected, with the value displayed in the first cell of the row.
If the values were coming from a data table this would obviously be easy. I've also found answers on how to show all of the selected parameter values in a single textbox using the JOIN function, but I don't want to do that.
The only solution I can think of is to replicate the list of available values in the multi-value parameter in a tablix manually, and link the visibility of each row of the tablix to the selected state of the corresponding value in the multi-value parameter, but that's not very elegant and increases the effort involved in maintaining the report definition.
Any ideas on how to do this? I know the selected values from the parameter simply form an array, but I can't see how to bind a tablix to any data that isn't in a dataset, or how to create a dataset from the parameter values.
Considering that a tablix sources from a dataset, I did some experiments to see how to create a low maintenance solution for you.
Option 1: Create a data set with hard-coded options to match your multi-value parameter and select those options WHERE they exist in the parameter.
Example:
SELECT val
FROM (
SELECT 'opt1' as val
UNION SELECT 'opt2'
UNION SELECT 'opt3'
UNION SELECT 'opt4') a
WHERE val IN (#Param)
Thoughts: easier to maintain than visibility on a table, but still two hard-coded places within the report.
Option 2: Create a dataset that selects the multi-value parameter and splits it by each value. This was my first idea, but I ran into some issues with determining how to actually select the multi-value without a syntax error. I came up with a method that creates a deliminated string in the report and than parsed that string back into rows in the dataset:
Step 1) Within the dataset properties, on the parameter tab, join the multiple values together with a JOIN expression
Step 2) Create a simple query which uses the new SQL Server 2016 function string_split. Note that your database compatibility level MUST be 130 or higher to use this function (SQL 2016+). If this isn't your scenario, there are many string split functions that you can find on Stack Overflow to achieve the same thing.
Fun problem!

Add filter option on each column of the data displayed in SSRS

I am generating a table in SSRS based on the selection made by the user on two filters: Filter1 and Filter2 (say). The table so displayed has 10 columns and I wish to add filter option listing all available values for that column for all 10 columns.
Basically, I am trying to replicate the Excel functionality of filtering down data on each and every column.
Please note that I tried creating a new data set and a parameter taking all distinct values for a particular variable. However, I am still not able to get the desired results by filter the tablix on that parameter
Is there a way I can do that?
You'd need to make a new dataset that is a smaller version of your main dataset. It would need to return all potential values for the column(s) you want to filter in a single column to be used in a parameter.
Without seeing the design of the report or the dataset itself it's quite hard to be more specific.

SSRS dynamic data retrieval from another dataset

I want to get data(dynamic) according to the data in another dataset and put the result in textbox of the different dataset.
Right now, the data I get is static and I tried to use many expressions but no avail.
Problem lies in editing textbox expression. Since I am getting data from different dataset, it always ask me to have dataset aggregate function in my expression. If I specified the dataset from where I am getting the data, then, I cannot make it dynamic - and I get the undesired result.
And another way out that I attempted is merging the data sets into one rather than having multiples and use it only but this was unsuccessful.
How can I make it work to get the result that I want:
By the way, the textbox and the tables are in different scope. I have tried to combine them in one scope too.
Getting data from another dataset requires an aggregate function because it can't tell what data you want from that dataset so it forces you to aggregate it so it can return a specific value rather than an entire list of values.
I think what you are after is the Lookup function. Lookup allows you to look up a value from another dataset based on a value in the table's dataset. To give a simplistic example, let's say your table was of employees and you had a department id on that table and another dataset called "Departments" which had an id and a name. You could look up the department's name using the following expression:
=Lookup(Fields!DeptId.Value, Fields!Id.Value, Fields!Name.Value, "Departments")
This uses the current table's dataset's DeptId field to look up the Departments dataset by the Id field and return the Name field.
=Lookup(First(ReportItems!EmpID.Value),Fields!EmpID.Value,Fields!Dept.Value,"dataset_which_u_retrieve_the_data_from")
Problem solved!By using reportItems instead of Fields because I am retrieving one data only,not the whole field.
Thanks guys for helping me out.

Passing distinct Multiple Parameters in SSRS

I'm in a peculiar situation here. I have a report which takes #ProjectID as a parameter and shows all the info related to that project.
Now I have to pass multiple project ids separately as parameters to the report and each report(ProjectID) should show in a distinct page.
I did research on Multivalues parameters but could not find a way to accomplish this. Any advice is much appreciated.
Create the #ProjectId parameter as multivalue
In your SQL query use the multivalue parameter using IN eg. WHERE ProjectId IN (#ProjectId)
Add a table group, grouping on ProjectId field. In the group settings enable "Page break at end"
