Make the binding method in user control UsrCtrl public and call it from selectedIndexChange event of dropdown in the main page.

In UsrCtrl 

public void BindMyGrid(string selectedValue)
{
     //Bind grid here
}

In aspx Main.aspx

protected void ddl_SelectedIndexChanged(object source, EventArgs e)
{
   UsrCtrl.BindMyGrid(ddl.SelectedValue);

}
