in my table i have hidden some rows where ever the null values are there . so if i write the expression for calculating number of rows [ RowNumber("Table") ], the row number which are hidden are also taken into consideration and serial number is not in the sequence

What I have tried:

RowNumber("Table")
CountRows("DataSet")
Count(Field!FieldName.value,"Datasetanem')
RowNumber(Nothing)

That is correct because the number of rows remains constant regardless of whether rows are visible or not.

Please, read this: RowNumber Function (Report Builder and SSRS) - SQL Server Reporting Services (SSRS) | Microsoft Docs[^]
The most important is:

Quote:
RowNumber returns a running value of the count of rows within the specified scope, just as RunningValue[^] returns the running value of an aggregate function. When you specify a scope, you specify when to reset the row count to 1.

So, the only way to achieve this, is to group rows by non-nullable values. Or use the trick from: reporting services - SSRS Row Number within table excluding hidden rows - Stack Overflow[^]
