I have a datagridview1 where I load it with a sql statement and I used datagridview1.datasource =nothing then clear and clearselection This will clear the datagridview1  I repopulate the datagridview comes up with 2 records for every 1 record if I run it a third time the datagridview comes up 3 times for that 1 record is there a way to just havethe datagridview just load data once I assume the dataset is not being destroyed. That's another thing if a user selects a certain team that dataset I cannot change. How do I release a dataset and repopulate it

Do you reinitialize the datatable/dataset as well? Add following before your .Fill method call

YourDataTableName = New DataTable

or

YourDataSetName = New DataSet
