Some SSRS controls, such as charts, that reference NoDataMessage property have by default the “No Data Available” caption to handle instances whereby an empty result set is returned.

When SQL Server Reporting Services (SSRS) successfully renders a given report control (i.e., Table, Matrix, List, etc.), the result set can either be empty (which means no data returned) or actually show data. In cases whereby an empty result set is returned, SSRS controls, such as tables and charts, use NoDataMessage and NoRowsMessage properties to inform report users of no data.

Fortunately, some SSRS controls, such as charts, that reference NoDataMessage property have by default the “No Data Available” caption to handle instances whereby an empty result set is returned. To illustrate this point – I have an SSRS dataset in my report that sources HumanResources.vEmployee object from the AdventureWorks2012 Sample Database. I have also created another dataset that will be used to populate report country parameter.

report main dataset

SQL

SELECT
    [BusinessEntityID]
    ,[FirstName]
    ,[LastName]
    ,[JobTitle]
    ,[PhoneNumberType]
    ,[City]
    ,[StateProvinceName]
    ,[CountryRegionName]
FROM [AdventureWorks2012].[HumanResources].[vEmployee]

country parameter dataset

SQL

SELECT 'Australia' Country
UNION
SELECT 'Canada'
UNION
SELECT 'Germany'
UNION
SELECT 'France'
UNION
SELECT 'United Kingdom'
UNION
SELECT 'United States'
UNION
SELECT 'South Africa'

NoDataMessage Property

I have used aforementioned datasets to add a vertical bar chart in the report that shows a number of Adventure Works employees by country of origin. By default, the report looks as follows:

Default Report View With All Countries Selected

As shown in the above chart, United States has the most number of employees working for Adventure Works. The following images show the report filtered by France and later by South Africa. Whilst a single French employee is found, there are no South African employees and thus the “No Data Available” message is shown.

Report Filtered by France

Report Filtered by South Africa – No Data Available

NoRowsMessage Property

Unlike controls that reference NoDataMessage property, SSRS controls that handle empty result sets using the NoRowsMessage property – do not have a default caption. To illustrate this point, we again use the dataset that determine the number of Adventure Works employees by country of origin, however, instead of a using a chart control, we will display result into a table.

Table Based Off All Countries

Again, when we filter the report by France – we are able to find the single French employee.

Table Filtered by France

Table filtered by South Africa

When the report is filtered by South Africa, as shown below, no data is found – however, unlike the chart control, the “No Data Available” caption is not shown in the table. We could fix this by editing the value of NoRowsMessage property. This is done by:
