I have a report in SSRS which is generated for around 50-60 items.

Say, the report shows Country name on one scale and their population on another.
When the graph is generated, it shows around 100 countries.
If I want to see population of only UK, US, India and China. Then I Should have an option to select the countries of my choice.

Having one dropdown and allowing them to select only one country at a time is simple.

I have no idea on how I can have a checkbox in dropdown to allow multiple selections.

TIA.

    You’ll want to search for Multi-valued Parameters. If you open the properties of the parameter there will be an option something like “Allow multiple values”. Reporting services will handle the UI with checkboxes.

    One important thing to know about multi-valued parameters is how to use them in your query. Suppose your parameter @CountryId is being filled with this query:

    SELECT CountryId, -- This will be the value for the parameter
       CountryName, -- The label for the parameter
FROM   Country

    If you set this parameter to allow multiple-values, reporting services will generate the multi-select UI for you. When executing any subsequent query that uses the parameter, before sending the query to your SQL server it will replace the parameter with a comma-seperated list of CountryId values. So this query:

    SELECT  *
FROM    MyDataTable
WHERE   MyDataTable.CountryId IN (@CountryID)

    Will be sent to SQL server as something like this, supposing there are 3 countries selected:

    SELECT  *
FROM    MyDataTable
WHERE   MyDataTable.CountryId IN (1001,1002,1003)
