I have a combobox and a gridview. whenever an item from the combobox is selected , the gridview should be populated with related records.
My question is how can we refresh the datagridview with new data and remove the old one.
Right now when i click on combobox item A , the gridview displays item A records.
Then when i select combobox item B, the gridview displays Item A and B records.
I only want item B records to be displayed
