I am using V Studio 2005, VB. In my application, I am asking the user to enter an ID and click on Search button. Now, when the user enter an ID for the first time, all the columns and rows appear fine in the DataGridView. When the user enters an ID second time (or third, etc), I want to erase the previous contents of the DataGridView and display the new values. For this, I am using .Clear() method of DataGridView which isn't giving me what I want. It is simply clearing the "previous values" and not deleting the "row".
