How to show distinct rows of the column of the dataset and number of distinct rows of that colum

suppose i have aDataset with 11 rows. field1 with 5 rows of aaa, 6 rows of "bbb"

I want's some thing like

field1 rowcount
aaa 5
bbb 6

Have a table and map it to the dataset. Insert a group (say table_Group1) to the table with the grouping column being "Fields!field1.Value". In the group header row of your table, use Fields!field1.Value and CountDistinct(FIelds!field1.Value, "table_Group1") to get your desired values.
